I would like to know what will happen to the Luns that belong to the SG ..in my opinion they will remain in the SG as unassigned Luns ..or is there a possibility that the lUns will move back to the storage.

• Is there a system monitoring tool that lets me write complex queries against the data?

  - by benhsu

• How can I record system sounds (apps) in Audacity?

  - by Alex

  Or another similar program? All I want to do is record the sounds coming from say firefox, or any other app, for use as samples in music. I need to do this in both windows and linux (ubuntu 9.10). I have looked through the preferences of audacity but didn't find anything that let me select the system sound. Perhaps I overlooked it, because I was able to do this with earlier versions of audacity.

• Managing hosts and iptables in scalable architecture

  - by hakunin

  Let's say I have a load balancer in front of 3 app servers. Let's say I also have these services available at certain IPs: Postgres server Redis server ElasticSearch server Memcached server 1 Memcached server 2 Memcached server 3 So that's 6 nodes at 6 different IP addresses. Naturally, every one of my 3 app servers needs to talk to these 6 servers above. Then, to make it a bit funkier, I also have 3 worker servers. And each worker also talks to the above 6 servers, but thankfully workers and apps never need to talk to each other. Now's the kicker. Everything is on Digital Ocean VPS. What that means is: you have no private network, no private IPs. You only have separate, random IP address on each machine. You can't mask them or anything. So in order to build a secure environment I would have to configure some iptables. For example: Open app servers be accessed by load balancer server Open redis, ES, PG, and each memcached servers to be accessed by each app's IP and each worker's IP This means that every time I add an app or worker I have to also reconfigure iptables in those above 6 servers to welcome the new app or worker. Is there a way to simplify this type of setup? I was thinking — what if there was a gateway machine between apps/workers and the above 6 machines. This way all the interaction would always happen via the gateway server, and when I add a new app or worker I wouldn't need to teach the 6 servers to let it in. If I went this route, then I'd hope a small 512mb server could handle that perhaps, and there wouldn't be almost any overhead. Or would there? Please help with best way to handle this situation. I would appreciate an answer as concrete as possible. I don't think this is too specific, because this general architecture is very common, and Digital Ocean is becoming increasingly popular. A concrete solution here would be much appreciated by many.

• Automatic backup software?

  - by Mehrdad

  Every backup software I've seen (even the ones that claim "continuous" protection) only backs up files periodically -- say, every 5 minutes. What I'm looking for is true continuous backup software, i.e. software that can transparently back up files immediately before they are written to, so that I can be certain I have all the versions of a file that ever existed. Is there any software that does this?

• Can all notebooks record from the sound card?

  - by Stefan Walter

  Is it possible that a modern notebook (say built in the last 5 years) contains a (onboard) sound card that it is not possible to record from? I've always assumed that this is a very basic capability, but since I can't get it to work, I would like to check that before I put any more effort into it. In case it matters, my notebook is an ASUS UL50VT, I'm trying with Sound Recorder and Audacity under Ubuntu, but I am, at this point, not asking for "Try that"-support or software recommendations.

• Is there a way to make Notepad++ auto-complete words on {TAB} instead of {ENTER}?

  - by Andrew Cheong

  Is there a way to make Notepad++ auto-complete words on Tab instead of Enter? Currently, if want to type, say, frame, then Enter to begin a new line, instead the Enter will select the first auto-complete suggestion, like frameElement:      I do want the auto-complete feature, but I'd rather have a key like Tab do the actual selection, because Enter is frequently purposed toward starting a new line, whereas Tab is rarely used to indent after a word (since indenting is usually done at the start of lines), and so perhaps would be better repurposed toward auto-completion.

• Single click to accept meeting invite in Outlook 2010

  - by EMP

  In Outlook 2003 when I received a meeting invite I could click the Accept button once to accept it. In Outlook 2010 I have to click Accept, then click "Send the response now", which is completely useless - what else do I need to say other than "yes, I'll be there"? How do I restore the old behaviour so that a I can accept with a single click? (Declining is different, of course - I might want to edit the message then.)

• Firewall - Preventing Content Theft & Rogue Crawlers

  - by drodecker

  Our websites are being crawled by content thieves on a regular basis. We obviously want to let through the nice bots and legitimate user activity, but block questionable activity. We have tried IP blocking at our firewall, but this becomes to manage the block lists. Also, we have used IIS-handlers, however that complicates our web applications. Is anyone familiar with network appliances, firewalls or application services (say for IIS) that can reduce or eliminate the content scrapers?

• Setting Keyboard Shortcuts in Ubuntu

  - by joemangrove

  Is it possible to do the following in Ubuntu? If so can someone point me in the right direction. Say you want to set a keyboard shortcut to do the following: For examples sake, set Alt+F to open Firefox and maximize it, but only if Firefox is not already running. If it is running and not maximized, then maximize the most recently touched Firefox window. If it is maximized, then minimize Firefox. Thanks, Joe

• What's the reason to break HDD to few partitions for MDADM+LVM2?

  - by archer

  I'm using 2 HDDs each 1TB in size. I'm going to create MDADM+LVM2 over them. Initially I though about this partition layout: /dev/sda1 - 1Gb (boot) /dev/sda2 - 500Gb (md0) /dev/sda3 - 499Gb (md1) /dev/sdb1 - 1Gb (boot) /dev/sdb2 - 500Gb (md0) /dev/sdb3 - 499Gb (md1) md0 is going to be raid0 and md1 is going to be raid1 however, I found some info that this would be better to break each drive to more partitions (lets say 10 partitions 100Gb in size each). What's the reason of doing that?

• stdout and stderr of script doesn't get redirected when executed by cron

  - by gletscher

  Hi, when I execute ./script &>> log.txt I get a nice logfile, but if I have the same command executed by cron, lets say the crontab looks like this: * * * * * '/home/user/script &>> /home/user/log.txt' the log.txt will just be empty, I tried " and ' and ` and no ticks to enclose the command, any idea why the streams won't get written into the file?

• Lazy linux backup system?

  - by Alex

  Ok, so I want to say Time Machine, but that's note exactly what I'm looking for. I want to set up a system that will regularly (hourly?) back up the /home directory of our machine. time Machine style things are naturally preferable since they save space by only saving the changes, but honestly, this is important enough that I can suffer some waste. Any ideas?

• I want to press a key combination in OpenBox and have a terminal appear below my resized Chromium window

  - by Erik

  This is one of those things that looks like it might have a simple solution but is rather time consuming once you start investigating PyTile, Xnee and the likes. I know, I should just use a tiling window manager etc., but I suppose it can be done in OpenBox, and I am just hoping somebody already has a working solution. Ok, so I want to press a key combination while I am in an OpenBox session (Lubuntu LXDE to be more precise) and have my terminal appear below my then resized Chromium window (say ~60% Chromium and ~40% Terminal).

• What tools exist for monitoring the CPU and memory utilization of Firefox?

  - by vfclists

  Firefox appears to using too much memory and cpu even when it is idle What tools exist for monitoring the CPU and memory utilization of Firefox? I am thinking of an equivalent of Sysinternals Process Explorer for Firefox or something like top or htop, on a page, script and addon basis. More technically oriented, something I can see and hand over to the script designers or Mozilla and say "see what this doing to my browsing experience!!"

• Multiple [Stand-alone] zip files creation?

  - by im_chc

  How can I automatically zip a group of files into multiple zip files (say, 2mb in size for each file), and that each zip file is a stand-alone zip file? (i.e. not mult-volume zip files, that you can't lost any one of the files, otherwise you can't unzip) Is there any tools available to do so? Actually I just need to group the files into many groups, 2mb each etc, zipped or not zipped doesn't matter thx!

• Trying to grok Linux quotas, where is the data stored?

  - by CarpeNoctem

  So all the tutorials and documentation for the Linux quota system has left me confused. For each filesystem with quotas enabled/on where is the actual quota information stored? Is it filesystem metadata or is it in a file? Say user foo creates a new file on /home. How does the kernel determine whether user foo is below their hard limit? Does the kernel have to tally up quota information on that filesystem each time or is it in the superblock or somewhere else? As far as I understand, the kernel consults the aquota.user file for the actual rules, but where is the current quota usage data stored? Can this be viewed with any tools outside repquota and the like? TIA!! Update: Thanks for the help. I had already read that mini-HOWTO. I am pretty clear on the usage of the user space tools. What I was unclear on is whether the usage data was ALSO in the file that stored per-user limits and you answered this with a yes. From what I can tell, rc.sysinit runs quotacheck and quotaon on startup. The quotacheck program analyzes the filesystem, updates the aquota.* files. It then makes use of quota.h and the quotactl() syscall to inform the kernel of quota info. From this point forward the kernel hashes that information and increments/decrements quota stats as changes occur. Upon shutdown, the init.d/halt script runs the quotaoff command RIGHT before the filesystems are unmounted. The quotaoff command does not appear to update the aquota.* files with the information the kernel has in memory. I say this because the {a,c,m}times for the aquota.user file are only updated upon a reboot of the system or by manual running the quotacheck command. It appears - as far as I can tell - that the kernel just drops it's up-to-date usage data on the floor at shutdown. This information is never used to update the aquota.* files. They are updated during startup by quotacheck(rc.sysinit). Seems silly to me since that updated info had already been collected by the kernel. So...in conclusion I am still not entirely clear on the methods. ;)

• windows 7: Can I make it automatically download updates during one period and install them in anothe

  - by askvictor

  When Windows 7 is configured to automatically update at a certain time (say Friday 5pm), is that also when it tries to download updates, or does it pull in the updates throughout the week, and only installs them at the update time? UPDATE: So I actually want the machines to download during one set of times (9am-3pm Mon-Fri), but install during another set of times (e.g. 5pm Friday). Is there a way to achieve this?

• Difference between Content Protection and DRM

  - by BlueGene

  In this recent post about criticism regarding built-in DRM in Intels SandyBridge processors, Intel denies that there's any DRM in Sandybridge processors but goes on to say that Intel created Intel insider, an extra layer of content protection. Think of it as an armoured truck carrying the movie from the Internet to your display, it keeps the data safe from pirates, but still lets you enjoy your legally acquired movie in the best possible quality I'm confused now. So far I was thinking DRM is content protection. Can someone shed light on this?

• How much memory do I need for innodb buffer pool?

  - by Shirko

  I read here that You need buffer pool a bit (say 10%) larger than your data (total size of Innodb TableSpaces) On the other hand I've read elswher that innodb_buffer_pool_size must be up to %80 of the memory. So I'm really confused how should I choose the best size for the pool. My database size is about 6GB and my total memory 64GB. Also I'm wondering if I increase the buffer pool size, I should shrink the number of maximum connections to make room for extra buffer, or these parameters are independent. Thanks
