• Ubuntu 10.04->10.10 in failed state - how to recover?

  - by Harvey

  I was running Ubuntu 10.04 and attempted to upgrade to 10.10. I have a really slow connection (DSL 128kbits/sec) and copying the upgrade files took about 26 hours. I of course let it run unattended. When I came back, I notice the following 3 dlgs: (1) "Could not install the upgrades The upgrade has aborted. Your system could be in an unusable state. A recovery will run now (dpkg -- configure -a)." (2) "gpk-update-icon Distribution upgrades available maverick 10.10 (stable) [more information] [Do no show this again] [Cancel] [Ok]" (3) "gpk-update-icon Security updates available The following important updates are available for your computer: libwebkit-1.0-2-dbg - Web content engine library for Gtk+ - Debugging symbols libcupsimage2 - Common UNIX Printing System(tm) - Raster image library ..." What is the best response to all of this? I went through something similar in an attempted network upgrade from 8.04 to 10.04 and had to reload the unbootable machine fresh from distribution media (all data was lost). I'd like to avoid that here. I have not yet responded to the dialogs, and want to make sure the system is still bootable and not lose my data this time.

• Orphaned SQL Recordsets/Connections with IIS

  - by Damian

  I have an IIS 6 site running on Windows 2003 Server x86 with MS SQL2005 Enterprise edition running ASP Classic (no choice). The site runs very fast with about 8000 page views per hour. All of my SQL tables are indexed and I have used the profiler to check my queries, the slowest of which is only about 10-15ms. I have autoshrink disabled, autogrow is set to 250mb, database is 2gb with 800mb of free space. My problem is that every now and then the site will slow to a crawl for no reason. Pages that just have a simple 'connect to databse and increment a hit counter' work ok, but more SQL intensive pages that normally execute in about 60ms take 25,000ms to run. This happens for about 30 seconds and then goes away. I was having an issue with orphan recordsets and connections due to the way I was releasing them. I have fixed this up and the issue is much better, but I am still getting them. Is there a way with permon, etc. to track when SQL Server or Windows closes these Orphan connections? At least if I can monitor the issue I will know if I am making progress or if I am even looking at the right things. Is there anything else I might be missing? Thank you!

• Access denied to external USB disk; update access rights fails in Windows 8

  - by gerard

  I use to work with 2 laptops (Windows vista and Windows 7), my work files being on an external usb disk. My oldest laptop broke down, so I bought a new one. I had no option other than take Windows 8. I suspect something changed with access rights, as my external disk suffered some "access denied" problem on Windows. I was prompted (by Windows 8) somehow to fix the access rights, which I tried to do, getting to the properties - security. This process was very slow and ended up saying disk is not ready Additionally, my external usb disk somehow was not recognized anymore. Back to Windows 7, I was warned that my disk needed to be verified, which I did. In this process, some files were lost (most of them I could recover from the folder found00x, but I have some backup anyway). Also, I don't know why, but under Windows 7, all the folder showed with a lock. Then back again to Windows 8. Same problem : access denied to my disk + no way to change access rights as it gets stuck disk is not ready". Now I am pretty sure there is some kind of bug or inconsistency in Windows 8 / Windows 7. I did 2. and 3. a few times. At some point, I also got an access denied in Windows 7. I could restore access rights to the disk to "System" (properties - security - EDIT for full control to group "system". ). But then I still get the same access right pb on Windows 8, and getting stuck in the process to restore full control to "system" -- and "admin" groups. I upgraded Windows8 with the Windows8 updates available. Does not help.

• External Storage for 2TB of backups and 4TB of data RAID level? HW vs Software?

  - by Jerry Mayers

  I have a Mac Mini set up as a media center/file server. Currently I just have a hodgepodge mess of external drives for storage. I'm maxed out, and I have some new laptops on the way with much larger drives and I need to work out a good storage solution for backing them up, as well as storing media on the server. I need around 2 TB of storage for the time machine backups from my various systems and around 2 TB more for media. I would like to build this to handle around 6 TB total so I have some growing room. Since I'm using a Mac Mini as the server I need to use external enclosure(s) that support USB 2 or Firewire 800 (preferred) or gigabit Ethernet. Performance of the system isn't a huge concern since the majority of the access from other computers is done over 802.11N. I plan on using 2TB drives, for the final version, but initially I'll try and use my existing 2 (1TB) drives + some new 2TB drives, and swap the 1TB ones out as I fill up. As to the actual questions: Should I use hardware RAID in some enclosure? Because if the enclosure dies I have to find an identical one to get to my data right? Wouldn't a software RAID be better as I can use any method of connecting the drives to the system? Remember OS X server is my OS. What if I had to reinstall OS X, can I restore the software RAID easily? What RAID version should I use? For the 2TB used for the time machine disk I don't see why I need RAID here, just a single 2TB drive since its already the backup, but for the remaining 4TB it would be the only copy of the data so I should build some redundancy. I had a RAID 5 setup using a cheep RAID PCI card years ago running RAID 5 in a 2 TB array and when a drive died it wanted 48 hours to rebuild. Is this crazy slow for a setup of this size or is this to be expected? Any suggestions as to drive enclosures?

• ACDSee alternatives for batch editing images

  - by Oxwivi

  I am looking for free, preferably open, alternatives to ACDSee for batch editing work. While I can do much of the work well on ACDSee, it's not entirely satisfactory despite having to pay for it. I need at least the following batch editing functions: Resize using either height or width and maintain aspect ration Auto contrast text overlays and occasionally, cropping oh, I make extensive use of renaming features as well Couple of issues with ACDSee are: I always need to highlight the Exposure section or auto contrast will not be done despite it being saved in the preset; and I can't define, move around the cropping box, forcing me to manually crop tons of images. I'm not an advanced, or "power photo-editor". I only require the basic stuff I described to be automated. My personal feature wish list (I'm pretty sure something so niche doesn't exist) would be text overlay based on the image names (images are named as image-1_1, image-1_2 or image-2_c1_1, image-2_c1_2, and text overlay would Image-1 and Image-2 C1 and Image-2 C2). I tried digiKam, but damn that thing is huge. It runs very slowly on my Pentium 4 and 1.5 GB RAM. On top of being a program with over 1 GB of files, the KDE library it uses is always slow regardless of it running on either Windows or Linux.

• configuring lighttpd for large downloads

  - by ahmedre

  i run a web site that hosts pages that are just general scripts (php, etc) and mp3 downloads (some of which are fairly large - up to 200mb). i am running lighttpd on the servers on linux (ubuntu 64). everything is fine, but under high load, the server is not accessible (or very slow - even sshing in takes a while), and i am guessing this is due to a huge number of mp3 downloads at that time. consequently, dns sees the server as down and redirects all the traffic to the other servers, and after a while, it comes back up and things work again. so what's the best way to fix this? ideally, i want the server to continue running (and the web pages - php etc - to always work, but downloads don't always have to work). should i just have 2 web servers running (one for the downloads and one for the php pages), or is it perhaps something i can fix in my lighttpd configuration? here are the snippets from my configuration: server.max-worker = 4 server.max-fds = 2048 server.max-keep-alive-requests = 4 server.max-keep-alive-idle = 4 server.stat-cache-engine = "fam" fastcgi.server = ( ".php" => (( "bin-path" => "/usr/bin/php-cgi", "socket" => "/tmp/php.socket", "max-procs" => 1, "idle-timeout" => 20, "bin-environment" => ( "PHP_FCGI_CHILDREN" => "64", "PHP_FCGI_MAX_REQUESTS" => "1000" ), "bin-copy-environment" => ( "PATH", "SHELL", "USER" ), "broken-scriptfilename" => "enable" )) ) # normal php site $HTTP["host"] =~ "bar.com" { server.document-root = "/usr/local/www/sites/bar.com/" accesslog.filename = "|/usr/sbin/cronolog /var/log/lighttpd/%m/%d/%H/bar.log" } # download site $HTTP["host"] =~ "(download|stream).foo.com" { server.document-root = "/home/audio/" dir-listing.activate = "enable" dir-listing.hide-dotfiles = "enable" evasive.max-conns-per-ip = 1 evasive.silent = "enable" # connection.kbytes-per-second = 256 accesslog.filename = "|/usr/sbin/cronolog /var/log/lighttpd/%m/%d/%H/download.log" }

• GVIM hangs when saving through GVFS' FTP

  - by Lie Ryan

  I loved Gnome's Nautilus and FTP integration and being able to mount a remote FTP directory as a regular bookmark/directory, and double clicking any remote files to open in any unmodified program. I also loved editing text files with GVim. However, if I double clicked file on Nautilus to open a text file in Gvim, then saving a file will take about 10 seconds and GVim will hang for that amount of time. The major irritant is that I cannot continue editing while the text editor is waiting for the write to finish, this delay interrupted my workflow and thought process and saving becomes a painful process. The other problem is that I don't think simply uploading a file should take that much time. I'm aware of GVim's internal FTP support, but they are not as well integrated with Nautilus's FTP. So a few question: Is there a way to make GVim or GVFS to save in background while I continue editing? Why is GVFS so slow? Is there any way to set GVFS to use a single persistent FTP connection instead of creating a new FTP connection each time? I'm on Gentoo Linux x86-64.

• Rate limiting bandwidth per IP

  - by Yohan

  First, I am not that good with computer. I even had problem with Windows PC. Right now I own a restaurant which happened to offer free internet. My ISP has my connection setup using a Ubuntu 11.1 box. IP Address is 192.168.1.16 with netmask 255.255.0.0, dns is 192.168.1.1 and gateway is 192.168.1.1. My problem is that my customers complains all day about slow network. When I received that kind of complain, the first thing came to my mind is to scout my area and find out who is the culprit, and ask him not to waste our bandwidth. Now, it is getting bored scouting people around, and I need to implement to my Linux box to limit bandwidth. I don't care if their provider can't be faster, but I want to limit 70kbit for each person. More annoying are people who use flashget and torrents. Usually they consume the biggest bandwidth. My question, how can I limit that? Please guide me in easy way. I've spent few days reading tc documents but doesn't understand a thing. I am using Ubuntu 11.10 Basically, I want all my customer get 70kbps each, no matter what.

• Alfa AWUSO36H 1W dysfunctional driver

  - by BrainStorm

  I recently purchased an Alfa AWUSO36H 1W wireless USB adapter for my notebook, in order to improve signal strength and quality. I'm currently using Linux Mint 11, and the it uses the RTL8187 driver for this adapter, I'm also using a 4dbi antenna, though I have others. The problem is that this adapter does exactly the opposite of what it should, actually my internal Broadcom BCM4313 adapter works way better than the alfa. Browsing is slow, some network applications don't even work, pings against Google.com on the internal adapter runs smooth, while in the alfa it gets like 25% packets lost or more! I'm less them 50 feet from my AP, the internal adapter gets 44/70 link quality, and the alfa gets around 60/70 (iwconfig output). Also the system always sets alfa power to 20dbm(100mw), then I have to do sudo iw set reg B0 to make it 30dbm(1000mw), but apparently no significant change. I've installed wireless-compat drivers, no change either. And worst of all, in Windows 7 it works way more smoothly for browsing, though I couldn't test it properly there. I hope its a driver problem, even if it's a pain to find/compile Linux drivers for a starter, I prefer it to a hardware problem where I would need to buy another adapter, since I have no money left (except for the cantenna pieces).

• Hard drive degredation from large memory usage and paging files?

  - by Stephen R

  I've had a question(s) regarding computer degradation going through my head for a while and haven't found many good resources for researching it. 1) First off, when is the virtual RAM/paging file on a hard drive used by Windows? Is it used when the RAM is full? Or does it use the Virtual RAM/paging file as intermediate caching between the RAM and actual hard drive space all the time? 2) If I were to run many applications on my computer at the same time and have a bad habit of doing this for the entire lifetime of the computer, does it use more of the virtual RAM/paging file than if I were to have fewer programs running? Just to note, the RAM never fills up on my computer but it is used heavily. 3) By extension of question 2, if the virtual RAM/paging file is used more heavily, would that result in rapid hard drive degradation? I have seen a pattern among all of the computers that I have owned or used in the past 5 years. I am the kind of person to leave my web browser up with 40 tabs among other programs which will eat up 40% of my memory typically. Over time my computer will slow down, browsers start crashing, programs start seizing up or crashing themselves, eventually the computer becomes essentially unusable. I have been trying to rack my mind to come up with a solution other than to purchase a new PC to have it die on me in the next couple years as well. This is the only thought that has come to mind that might have a simple hardware fix...Windows ReadyBoost...Maybe? I'd like to be able to discuss this so I can learn something about all of the above. Thanks.

• 100% CPU load on Ubuntu 10.04.3 LTS 64bit

  - by deadtired

  I have 2 days since I am trying to fix this issue, with no success. The server is a mysql database server. Hardware: DELL Poweredge 1950, 2x Intel Xeon Quad Core E5345 @ 2.33GHz, 16 Gb mem, 2x 146Gb SAS (software RAID1) Software: Ubuntu 10.04.3 LTS, MySQL 5.1.41 Issue: while mysql is not used and runs with no database, everything seems alright. As soon as I install a database, it has the reason to bring all 8 cores in 100% with low memory consumption. So, you can imagine the load average goes high (I saw 212 load average for the first time). The server doesn't become unresponsive, but you can see it's slow while browsing the project installed. Additional info: the database used is not more than 24MB and it was moved from a server with less resources and a lot more larger databases. So it's not the database/project. my.cnf is not a reason also, as I used both default one and the one I use on the same distribution on another server.What is interesting is that mysql doesn't close any process and runs to the limit of the max_connections. Logs are quiet. Nothing there. I switched to this Ubuntu version after I suspected some problems in the newly Ubuntu 11.10 server. This one worked alright for an hour after I made a kernel upgrade to 3.0.1 (it was using the memory also) I tested disk speed and seems alright. Some more output on the running server: dstat -cndymlp -N total -D total 3: htop command: Idea? Did anyone meet the same problem? Any fix you can think of?

• Is 2 GB of RAM better than 2.5 GB?

  - by pibboater

  My laptop has two slots for RAM, and currently has two 512 MB chips, for 1 GB. Windows XP is running terribly slow on it, so I want to upgrade the RAM. I could buy two 1 GB chips to replace both of the current 512 MB chips, to give me 2 GB of RAM. Or, the price is the same to buy one 2 GB chip, to replace just one of the 512 MB chips, and give me 2.5 GB total. The RAM it takes is PC2-4200 533MHz DDR2. What do you think would be better: buying two 1 GB chips so it can take advantage of dual-channel operation, or buying one 2 GB chip to end up with more total RAM but not dual-channel operation? Like I said, price is the same, so performance is the only consideration. I'm not doing anything especially intensive like video or photo editing -- just having multiple Office programs open, playing music, browsers, etc., but currently even opening the first application takes forever. If it matters, the laptop is a Toshiba Qosmio G25-AV513 running Windows XP Media Center SP3. Thanks! Kevin

• Cut (smart edit) .mts (AVCHD Progressive) files un Ubuntu Lucid

  - by pts

  I have a bunch of .mts files containing AVCHD Progressive video recorded by a Panasonic camera, and I need software on Ubuntu Lucid with which I can remove the boring parts, and concatenate the interesting parts, all this without reencoding the video stream. It's OK for me to cut at keyframe boundary. If Avidemux was able to open the files, it would take about 60 hours of work for me to cut the files. (At least that was it last time I tried with similar videos, but of a file format supported by Avidemux.) So I need a fast, powerful and stable video editor, because I don't want that 60 hours of work go up to 240 or even 480 hours just because the tool is too slow or unstable or has a terrible UI. I've tried Avidemux 2.5.5 and 2.5.6, but they crash trying to open such a file, even if I convert the file to .avi first using mencoder -oac copy -ovc copy. mplayer can play the files. I've tried Avidemux 2.6.0, which can open the file, but it cannot jump to the previous or next keyframe etc. (if I make it jump to the next keyframe, and then to the previous keyframe, it doesn't end up at the original keyframe, sometimes displays an error etc.). Also I'm not sure if Avidemux 2.6.x would let me save the result without reencoding. I've tried Kdenlive 0.7.7.1, but playback is very choppy, and it cannot play audio at all (complaining that SDL cannot find the device; but many other programs on the system can play audio). It would be a pain to work with. I've tried converting the .mts file to .mkv using ffmpeg -i input.mts -vcodec copy -sameq -acodec copy -f matroska output.mkv, but that caused too much visible distortions in the video in both mplayer and Avidemux. I've tried converting the .mts file with TsRemux.exe, but Avidemux 2.5.x still can't open that file. Is there another program to cut and concatenate the files? Is there a preprocessor which would create a file (without reencoding the video) on which Avidemux wouldn't crash?

• Modify or disable Windows 8 swipe gestures on touchpad / laptop

  - by Matsemann

  I have an ASUS G75VW laptop with a Synaptic touchpad (/trackpad). When I move my finger from one edge towards the middle (the swipe), Windows 8 will bring up different stuff. This is a problem because the area where I can actually move the mouse with my finger is too small (or, I mostly use the top left of the touchpad). So I often end up doing a swipe and bringing up some menu, or to do the swipe so slow that no menu is appearing but the mouse pointer is also not moving when I move my finger. Quite annoying. When swiping from left edge it earlier swapped apps like crazy. I disabled that, so now it only brings up the same menu as pressing win+tab (or some times the charms bar, I never know which). I could change that by: Win+I - Change PC settings - General - When I swipe from the left edge, switch directly to my most recent app I've tried Mouse settings in Control Panel, driver settings for my touchpad and searching for swipe and gestures on my computer (which was what led me to the setting above) with no luck. How can I disable the swipe gestures, or change what they do? Thanks.

• Why isn't my phone charging with some micro usb cables?

  - by Jacxel

  I ordered 3 microUSB cables over ebay. My phone was at about 50% battery and I wanted to use it as a hot spot for some browsing on my laptop, so I plugged it in, a charging icon appeared on the phone, my laptop showed it as a connected usb device and so I went about my business. About 30 minutes later I checked the phone and to my dismay saw 45% battery. But ahh, I thought, I have been putting the poor little thing under too much pressure, acting as a WiFi hotspot must drain the battery quicker than it can charge via usb, perhaps even using my laptops usb port wouldn't output enough power. Unscathed I continued on and when I was going to bed I plugged the usb cable into a mains adapter and switched everything battery consuming off and content, went to sleep. The next morning I was awoken by my phones alarm which got cut off unexpectedly. I attempted to unlock my phone which showed no more signs of life. Why isn't my phone charging with these new USB cables? For clarity: They transfer data with no problems The phone appears to be charging, showing all the signs and lights it normally would, the cable that came with the phone works as you would expect, so its not a fault with the phone, I think they slow the discharging of the phone, but I could be wrong. Are these just bad quality cables? Is there a way to fix this issue?

• How to Set up MySQL Server to utilize more memory

  - by Cyril Gupta

  Hi there, I have MySQL setup on Windows along with Plesk. The version is 5.0.45 Community. The databases I have on the server are MyISAM as well as InnoDb, but predominantly innodb. I had 8G memory on my server, but MySQL isn't going up more than 1.3G and tweaking the settings isn't helping. I tried to increase the memory allocation for innodb_buffer_pool_size, it works if I set it up to 1G, but if I set 2G, or above the server doesn't come back online! I want mySQL to use at least 5-6 Gigs of the memory I have for performance, but I can't get this to work. Can anyone please help?

• How do you optimize your Outlook Exchange + IMAP setup?

  - by Mike

  My company provides an Outlook/Exchange account we must use for mail/calendar. Like many companies, they unfortunately also provide a ridiculously small mail quota. I got tired of managing and backing up .pst files (since I'm always in my e-mail there is never a good time to back it up), so I started storing my archived mail "in the cloud", using an IMAP server I set up on my Linux box. This has a few drawbacks for me: IMAP (at least the implementation in Outlook) is *very slow*. Furthermore, if I move a large number of messages to the IMAP server, it blocks the entire Outlook client for hours sometimes, which is quite annoying. Can't use exchange over HTTP to do mail without launching a VPN session, because the client-side rules I have which organize my mail fail and disable the rule if the IMAP server can't be reached. If I reply to a message from my IMAP store, I have to specify a SMTP server willing to relay for me in order to send e-mail, unless I always remember to select my Exchange account while composing e-mail. ... but the main advantage of being very easy to back up, with a couple of cron jobs that essentially do an 'rsync'. Short of moving the IMAP server to my local host (which seem like might have the same file locking problems as using a .pst), my options seem limited for solving (1). I'd like to come up with a solution for (2) and (3) though. For problem (2) would it be possible to somehow tell Outlook that the IMAP server is "offline", and have it synchronize my changes during a periodic "send and receive"? If so, I wonder if it would block the Outlook client, like it does in problem (1), and if it would be compatible with the client-only rules I use to sort my mail into folders. I've looked all over the options menu and have not found a way to tell Outlook to not use a certain account for sending mail, which would solve (3). Is anyone else crazy enough to be doing something like this? Any ideas?

• Mongo daemon restarts after replica set issue

  - by Matt Beckman

  We had a recent election in our replica set (2 read nodes; 1 write node) that changed the primary node. Curious as to why this occurred, I started looking through the logs to find out what happened. It appears that mongoNode2 could not communicate with mongoNode3. When both nodes could not communicate, it appears that this caused the services on mongoNode2 and mongoNode3 to restart, eventually resulting in a new primary after the services had been started again. Thu Jun 23 08:27:28 [ReplSetHealthPollTask] DBClientCursor::init call() failed Thu Jun 23 08:27:28 [ReplSetHealthPollTask] replSet info mongoNode3:27017 is down (or \ slow to respond): DBClientBase::findOne: transport error: mongoNode3:27017 query: { \ replSetHeartbeat: "myReplSet", v: 3, pv: 1, checkEmpty: false, from: \ "mongoNode2:27017" } Thu Jun 23 08:27:29 got kill or ctrl c or hup signal 15 (Terminated), will \ terminate after current cmd ends Thu Jun 23 08:27:29 [interruptThread] now exiting Thu Jun 23 08:27:29 dbexit: Is there any reason that the mongo service would restart due to a DBClientCursor::init call() failure? Is this a known bug? It should be noted that mongoNode2 and mongoNode3 are VMs on the same VMware host. MongoNode1 is not on the same host, and it did not have any issues with the service. However, I did not have any other reports of issues with other VMs on the VMware host.

• Copying windows home server backup offsite

  - by Simon

  What ways are there to copy a windows home server backup to an offsite location? I'm talking specifically (and only) about the automated backup of my entire machine, and not the shared network folders. I am 90% working away from home on my laptop which has a 640GB drive so the shared folders are essentially useless to me. I backup every night, but if my house burns down or broken into the I'm in serious serious trouble ! I'm really looking for some alternative way to back up my entire machine - which much not interfere with the reliability or speed by which my WHS backs up my laptop every night. Either a way to 'export' a complete machine backup from the server, or recommendations on non-conflicting software I can backup to a 1TB drive at work are what I'm looking for. Note: I believe that WHS uses its own completely proprietary backup and doesn't use things like any 'backup bit' or 'archive bit'. I just dont want to install some other backup software that will conflict. PS I'm now running Windows 7 and just realized that I should probably check out the backup functionality it gives me. I assume that won't conflict right! Edit: Thanks for the hosted solutions. I'd also appreciate ways to backup to an 'offsite' location that I control - like my office vs. my home. The hosted solutions I think will be too slow or expensive for my needs.

• Creating a bootable USB drive from a distro split over two DVD ISOs

  - by Kev

  I am searching and not finding the right way to do this. Please note, I don't think I'm trying for anything strange here. I just want to make a bootable USB stick of a single OS that happens to be larger than one DVD and happens to be larger than FAT32 will allow for in a single file. On our slow connection I spent a long time downloading CentOS 5.9's two DVD ISOs: CentOS-5.9-x86_64-bin-DVD-1of2.iso (4.4 GB) CentOS-5.9-x86_64-bin-DVD-2of2.iso (718 MB) I have a USB stick that I want to somehow get these two ISOs on. Since the first one is 4.4 GB, I can't use ISO2USB because it insists on FAT32. I cannot find an alternative that lets you specify more than one ISO image--of the same distro, I'm not trying for some fancy multi-boot thing--to put on the same stick. I guess I should have downloaded the CD ISOs, but I thought I was "saving time" because then I wouldn't have as many files to run through the md5 checker. There's no IMG file of the whole thing (only a net install version, which I don't want--I want to pre-download everything) otherwise I would've gone for that. So, given that I have these two DVD ISOs, how can I get them on a stick that will boot and make use of both of them properly to install CentOS somewhere? Again, I don't think this is anything out of the ordinary, yet I can't find software/docs that seem to support this. Am I stuck re-downloading everything in CD-sized ISOs just to do this? I found this, but it doesn't run on Windows. I am using Windows to prepare the stick.

• Large, high performance object or key/value store for HTTP serving on Linux

  - by Tommy

  I have a service that serves images to end users at a very high rate using plain HTTP. The images vary between 4 and 64kbytes, and there are 1.300.000.000 of them in total. The dataset is about 30TiB in size and changes (new objects, updates, deletes) make out less than 1% of the requests. The number of requests pr. second vary from 240 to 9000 and is dispersed pretty much all over, with few objects being especially "hot". As of now, these images are files on a ext3 filesystem distributed read only across a large amount of mid range servers. This poses several problems: Using a fileysystem is very inefficient since the metadata size is large, the inode/dentry cache is volatile on linux and some daemons tend to stat()/readdir() it's way through the directory structure, which in my case becomes very expensive. Updating the dataset is very time consuming and requires remounting between set A and B. The only reasonable handling is operating on the block device for backup, copying, etc. What I would like is a deamon that: speaks HTTP (get, put, delete and perhaps update) stores data it in an efficient structure. The index should remain in memory, and considering the amount of objects, the overhead must be small. The software should be able to handle massive connections with slow (if any) time needed to ramp up. Index should be read in memory at startup. Statistics would be nice, but not mandatory. I have experimented a bit with riak, redis, mongodb, kyoto and varnish with persistent storage, but I haven't had the chance to dig in really deep yet.

• Spreadsheet application that can handle big data OS X

  - by Peter

  I've been working with Excel for quite a while for some statistical analysis that I do regularly. The size of the data that I'm working with has gotten much larger as of late, however. The layout of the databases in question is quite simple, usually just three rows which includes a UNIX timestamp, and EST value, a proprietary numeric value and finally an average of the rows that have a timestamp +/- 1000 that row's timestamp (little AVERAGEIFS() formula). That formula and the EST conversion are the only formulas in the sheet. I'm beginning to work with files with 500,000+ rows. Running the average formula down the entire row takes forever. The end result is the production of print-worthy graphs. I'm looking for either a UNIX CL utility or separate spreadsheet/database application that can handle this amount of data without melting my CPU or making me wait an hour. Is there anything out there? TL;DR: Simple excel sheet with over half a million rows is getting too slow to work with. OS X alternatives?

• Does migrating 2 domain controllers between 2 datacentre requires both virtual machines to be shut down at the same time?

  - by Imagineer

  I was attempting to migrate 2 virtual machines that are domain controllers between 2 datacentres running ESX 3.5 and ESX 4.1. I was advised to shut down both domain controller at the same time during the migration process. This is to avoid USN Rollback and other replication issues. The following are the steps that I was planning to perform: 1. Shutdown both DC. 2. Copy both VMs files across to new datacentre using Veeam FastSCP (connection to both vCentre through IP address instead of hostname) 3. Power them up at new datacentre. 4. Configure Network interface/DNS/DHCP for both DCs in new datacentre I have tried to use Veeam FastSCP rather than VMware Standalone Converter is because its copying rather than converting. Someone also suggested that I use backup and restore app like Veeam backup and replication software. Sounds like a simple job, but after shutting down both DCs, the transfer rate using FastSCP is so slow registering only 1KB/s as oppose to the normal 1MB/s (or more). When that attempt to transfer failed, I tried to cold clone both DCs resulted in the both ESX hosts get disconnected. I have tried troubleshooting by referring to this - VMware KB - Diagnosing an ESX Server that is Disconnected or Not Responding in VirtualCenter It seems that the DNS being down is the caused of all unusual occurrence. The moment I powered up the DCs via VMware console command, the ESX host were able to connect to the vCentre again. How can I avoid such a pitfall again? Am I doing it correctly? Any help would be greatly appreciated! Thank you.

• Can MySQL use multiple data directories on different physical storage devices

  - by sirlark

  I am running MySQL with its data dir on a 128Gb SSD. I am dealing with large datasets (~20Gb) that are loaded and processed weekly, each stored in a separate DB for the purposes of time point comparisons. Putting all the data into a single database in unfeasible because the performance on such large databases is already a problem. However, I cannot keep more than 6 datasets on the SSD at a time. Right now I am manually dumping the oldest to much larger 2Tb spinning disk every week, and dropping the database to make space for the new one. But if I need one of the 'archived' databases (a semi regular occurrence) I have to drop a current one (after dumping), reload it, do what I need to, then reverse the results. Is there a way to configure MySQL to use multiple data directories, say one on the SSD and one on the 2Tb spinning disk, and 'merge' them transparently? If I could do this, then archiving would no longer mean "moved out of the database entirely", but instead would mean "moved onto the slow physical device". The time taken to do my queries on a spinning disk would be less than that taken to completely dump, drop, load, drop, reload two entire databases, so this is a win. I thought of using something like unionfs but I can't think of a way to control which database gets stored on which physical drive, because it works by merging on a directory level (from what I understand) so I'm still stuck with using multiple directories. Any help appreciated, thanks in advance

• UW-IMAP server, high load for one user

  - by Bruce Garlock

  We have been experiencing a very strange anomaly, with one specific user with our UW-IMAP server. We have about 75 users using the server, and one particular user, who is in about the middle as far as used storage keeps having issues with slow speed. Most of our users all use Thunderbird 2, or Thunderbird 3. Mostly 2, because of the performance issues we have had with 3. This user was on 3, and I downgraded him to 2. The performance has gotten better, but according to the imapd processes on the server, his username is using the most CPU % and CPU time. I've already done all the usual T/S'ing: Started profile from scratch, compacted folders, re-indexed, newer faster computer, etc.. Still, this users' imapd process is always using the most CPU on the server. For troubleshooting, we setup another user which has more usage, folders, etc.. than he does, but we don't see the users process taking up most of the CPU with the imapd process. So, it almost sounds like a particular email may be the culprit, but how can we find it, if thats the problem? This has been going on for a while, and he is a management person, so his patience is about to end. Does anyone have any ideas?
