• Zero-channel RAID for High Performance MySQL Server (IBM ServeRAID 8k) : Any Experience/Recommendati

  - by prs563

  We are getting this IBM rack mount server and it has this IBM ServeRAID8k storage controller with Zero-Channel RAID and 256MB battery backed cache. It can support RAID 10 which we need for our high performance MySQL server which will have 4 x 15000K RPM 300GB SAS HDD. This is mission-critical and we want as much bandwidth and performance. Is this a good card or should we replace with another IBM RAID card? IBM ServeRAID 8k SAS Controller option provides 256 MB of battery backed 533 MHz DDR2 standard power memory in a fixed mounting arrangement. The device attaches directly to IBM planar which can provide full RAID capability. Manufacturer IBM Manufacturer Part # 25R8064 Cost Central Item # 10025907 Product Description IBM ServeRAID 8k SAS - Storage controller (zero-channel RAID) - RAID 0, 1, 5, 6, 10, 1E Device Type Storage controller (zero-channel RAID) - plug-in module Buffer Size 256 MB Supported Devices Disk array (RAID) Max Storage Devices Qty 8 RAID Level RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, RAID 1E Manufacturer Warranty 1 year warranty

• ML 350 additional SATA RAID controller (mirror only)

  - by Nicholas

  I have a Proliant ML350 G8 with two SAS raid arrays currently set up - thereby maxing the default P420i raid controller. I need to set up a large video dump space in addition to this existing set-up (for non backed up, non-critical, temporary storage). I had planned to just add a 2TB SATA disk and plug it into the motherboard. However I it occurred to me the motherboard might have built-in mirror RAID support? Therefore I could use two SATA disks and have some semblance of redundancy. Is this possible? Or would I need to get a cheap raid card? Any recommendations?

• Mozilla Thunderbird 3.0.10: Messages are being sent back to me

  - by punkinette64

  When I send an email and I get a response, more often than not, in the To: is my email address. However, my email address also ends up in the From: column.The reply-from address is nowhere to be found;so I don't have any address with which I can send my reply, as both of them have just my email address. What am I doing wrong here? Is there some set-up in my Tools Options which is incorrect? The set-up in Options is pretty difficult to understand and it doesn't offer any to or reply-from choices. This is critical because I just cannot answer my emails because there is no one I can send a reply to.

• Is a rubber keyboard suitable for heavy use?

  - by Vilx-

  Every keyboard wears out with time, and mine has some age already. The day it fails is coming closer and closer. So I'm slowly starting to look around for a new one. I use the keyboard for gaming and programming, so it gets some pretty solid use. I also tend to eat by the computer, so there's plenty of... uhh... lifeforms down there. Anyway, I was looking at these rubber keyboards. They come pretty cheap (my local computer shop has one for less than $20) and they seem to have some nice properties. They can be easily cleaned, they're quiet, and can be rolled up when needed (plus no worries about spilled drinks). However I'm wondering what their type-ability is. If I can't write on it at a decent speed, the rest of the features don't matter. Not that I'm a fast typer, but being a professional progammer does give a boost to the skill. I couldn't find any reviews on the net so I'm turning to you. Who has used these keyboards and what was your experience? Perhaps there is something else I haven't though of why such a keyboard would not be a good idea?

• Scriptable FTPS client able to send Keep Alive to control port?

  - by schultkl

  We need a FTP client that satisfies the following constraints: Windows Command-line scriptable, so we can automate it...sorry, FileZilla (?) FTPS, as it seems to perform better than SFTP The ability to send KeepAlive commands to the FTPS control port No passwords sent on the command line...sorry, curl Number 4, above, is critical: we have set KeepAlive in some other clients (e.g., CoreFTP LE) but we seem to have some routing equipment in the server environment which drops our connection when transferring a 7GB+ file. We have also set passive mode and "resume transfer" functionality seems currently broken with this secure file transport server...so we need to download the file in one go. What FTPS clients might meet our needs?

• Natively boot Virtualbox Image

  - by isync

  I am faced with a Windows hardware/software problem left over from another person. It's on me to resolve. It's a mission critical setup. The situation is: I've got a physical server machine with: -Disk C:\ (one disk) containing a basic install of Windows Server 2008 R2, formerly Win Vista Pro, now gone. -Disk D:\ (software Raid) containing a VirtualBox disk image of a configured Windows Server 2008 R2 running SQL Server R2 among others. What shall I do now? Migrate all the stuff from the configured VM to the basic but natively installed C:\ Windows Server 2008 R2 (with the possibility of breaking stuff)? Or, Setting up the machine to "natively boot" the VM with the help of bcdedit.exe (something I've read about, what I've never done, what I don't know of if it works, if it hits performance, or if it is stable for production) For me, being old skool, I am in the process of de-virtualising everything (option 1). But I'd be happy if someone suggests I am ok to go down the "natively boot" route.

• Apache /server-status/ gives a 404 not found

  - by kapshure

  I am trying to solve a problem where Apache stats aren't displaying correctly in Munin. I've ran through quite a bit of checks and tests regarding Munin setup, but I think my issue is related to Apache, but my skill set there is lacking. first, system info: monitored server CentOS 5.3 kernel 2.6.18-128.1.1.el5 Apache/2.2.3 "server-status" directive in httpd.conf (i've cross-compared this with another system that i did a successful parallel install of Munin on, correctly showing Apache stats, and the directive below is the same for both) ExtendedStatus On <Location /server-status> SetHandler server-status Order deny,allow Deny from all Allow from 127.0.0.1 </Location> ran lynx http://localhost/server-status got HTTP/1.1 404 taking a look at Apache access_log: 127.0.0.1 - - [13/Oct/2010:07:00:47 -0700] "GET /server-status HTTP/1.0" 404 11237 "-" "Lynx/2.8.5rel.1 libwww-FM/2.14 SSL-MM/1.4.1 OpenSSL/0.9.8e-fips-rhel5" mod_status is also loaded: % grep "mod_status" /etc/httpd/conf/httpd.conf LoadModule status_module modules/mod_status.so iptables is turned off also i did notice that the ownership status on httpd.conf on this system is root.root.. whereas the system that is displaying correctly is apache.www -- not certain that this matters?? its got to be permission issue, but i'm not certain where the permissions are messed up. any thoughts on why the test of server-status is giving me a 404?

• Can I put /tmp and /var/log in a ramdisk on OS X?

  - by kbyrd

  For non-critical Linux systems, I often move things /tmp and /var/log to tmpfs to save on some disk writing. I've been doing this for a year or so and if I ever need the logs across reboots, I just comment out a line in /etc/fstab and then start debugging. In any case, I would like to do the same thing on OS X. I've seen posts on creating a ramdisk for OS X, but I'm looking for a more permanent solution. I always want /tmp and /var/log mounted in a ramdisk, with the ability to turn that off with a bit of cmdline editing in vi if I have to.

• FoxPro 2.6 DOS on Windows 7 64-bit

  - by Rolando

  I support a company that has a very old, mission critical, FoxPro for DOS 2.6 (FPD) application. For variuos reasons the company didn't adapt/migrate their app, which, ironically, has been running even better under Windows XP (and 32-bit Win7) because the OS allowed new features like more reliable networking, distributed printing, email integration. Unfortunately for this company, most new machines now come with a 64-bit version of Windows 7, which is incompatible with their FPD app. I know this time the writing is on the wall: the only long-term solution is to migrate their app. But I wonder if anyone can suggest a temporary alternative path, which doesn't involve either: a) downgrade 64-bit Windows to 32-bit, or b) run the app on a virtualized 32-bit XP Thanks! PS: Happy New Year!!!

• Best way to Duplicate a Laptop's Hard Drive One-to-One

  - by Urda

  I have a Lenovo X61 Tablet computer, with a plain SATA drive inside. I have windows 7 and Ubuntu 9.10 dual booting on the computer. I want to back up both of these OS's, and their special partitions (Windows 7 has one, and of course the Linux Swap). I want a one-to-one backup, all of my mission critical data is already backed up, but I would like to get a snapshot, and store it on a larger file server at home for quick recovery. What is the best approach to do this?

• Virtual box lost files

  - by Paul Lloyd

  I have been running Virtual Box on a Macbook Pro for a year or more, with an old version of Windows XP running on the virtual machine. Recently my Mac battery dies completely and I had left VB / Windows running. When I re-started the Mac, VB would not load. I reinstalled a recent download of VB from a DMG file I had stored. Now VB starts but when I try to start the virtual machine I get the following message, Failed to open a session for the virtual machine Windows XP. Failed to load VMMR0.r0 (VERR_SUPLIB_WRITE_NON_SYS_GROUP). Result Code: NS_ERROR_FAILURE (0x80004005) Component: Console Interface: IConsole {1968b7d3-e3bf-4ceb-99e0-cb7c913317bb} I have been backing up the MAC using Time Machine and have backups going back months. I really need to access the windows files as they have my Accounts and other business critical stuff. Any ideas please, or does anyone know where I can get some support for this combination of hardware / software, apologies I am a novice in this area. Thanks in advance.

• todo manager (gtd): subtasks, php

  - by kusoksna

  Currently I'm using todoist.com as GTD manager. I'm almost satisfied with it. Is there any foss software, that could provide next features? 1. unlimited (at least 5) subtask levels 2. easy way to complete tasks (like in todoist) 3. easy to edit tasks 4. php based (as i want to host it on my server) 5. due dates (including recurring) 6. labels, colors, etc will be good, but not critical PS: i already checked several similar questions, including Which GTD tool/webservice do you recommend? But haven't found suitable software yet.

• How to maintain one file across many production servers (Windows and Linux)

  - by Brien

  My organization wants to centrally manage an Oracle TNSnames file for all of their production servers. When that file changes, they want to be able to push out the changes to all servers that use it with a minimal effort. Approaches that have been considered: Centralized file server (drawback: if the file server or the network connection to the file server goes down, the servers have no access to the critical file) Subversion client on each server (drawback: using a source control tool in production, added complexity) Store an individual copy of the file on each server (drawback: changing the file contents involves making changes on many different servers) Update Can I use DFS to do this?

• fedora13 mouse change -I Beam

  - by tom smith

  hi. sorry to have to ask such a basic question!! i've got fedora 13, trying to figure out how to change the "I Beam" pointer. earlier, i had a "thin" "I Beam" pointer in my gedit/term windows. now, I have a "thicker/shadow" kind of "I Beam" pointer when i move the mouse over the gedit/term windows. obviously, i've made some change, but i can't figure out what I changed, or where this attribute is set. i've checked google/irc, as well as looked through the "system-preferences-appearance" with no luck.. i saw the customize part of the gui, and could resize the "arrow" but nothing for the "I-Beam". this isn't critical, but it is anoying!! any thoughts/pointers would be helpful. thanks

• How can I have APF block script kiddies that mod_security detects?

  In one of the vhosts' error_log I found thousands of lines like these, all from the same IP: [Mon Apr 19 08:15:59 2010] [error] [client 61.147.67.206] mod_security: Access denied with code 403.

There is no way someone hasnt thought of this before...

• Prevent Server Restart after Windows Updates

  - by eidylon

  we have a number of servers in our office, as a small hosting company, and these servers are critical to business, ... web server, mail server, db server, etc. On a semi-regular basis, when the machines get automatic updates, they just automagically reboot themselves in the middle of the night. A number of them have software which must be running on the console session (bad practice, I know, but out of my control). When they reboot themselves, these programs obviously shut down, leaving customers upset and services interrupted. How do you set a Windows Server 2003 R2 machine to NEVER automagically reboot itself after updates? And perhaps, if possible, to instead email someone so that they are aware it needs a pending reboot and can schedule it for the best time? Thanks in advance!

• SBS 2008 DNS issues in BPA

  - by evesirim

  I'm gettng constant Critical Issue events in the Small Business Server Best Practices Analyser & resulting SBS Console reports that begin "The DNS client is not configured to point only to the internal IP address of the server.". When I check the DNS Manager, there are two separate IPs listed, one ***.***.***.2 and the other ***.***.***.28. I have checked online after an ipconfig /all and have found the reason for this to be that the second IP is created by DHCP for RAS & VPN purposes. It seems to cause no conflicts of any detrimental result apart from constantly sending me error messages and alerted reports. Does anyone know of a way that I can change settings somewhere so that Windows accepts this second IP, or at least stops alerting me of its prescence? Perhaps a registry hack of some kind...? Many thanks in advance

• How to manage iowait over cifs?

  - by Silvia

  For backup purposes we have Cifs file Server running that contains encrypted containers for backing up the more sensitive data. The container is mounted with cryptsetup and loop as a local filesystem and the rsync is used for backups. Because the Cifs server is not the fastest machine ever built, running the rsync process results in an iowait on the servers running the backup which in turn drives Nagios into an email frenzy. The question is, how do reduce the iowait on the server? Configuring Nagios to not report seems more like a workaround then a solution. Stretching the backups over different time intervals is already done with little effect and spending money is also not an option because apparently, we are talking about a "non-critical system".

• Deleting large no of files on linux eats up CPU

  - by Sanjay

  I generate more than 50GB of cache files on my RHEL server (and typical file size is 200kb so no of files is huge). When I try to delete these files it takes 8-10 hours. However, the bigger issue is that the system load goes to critical for these 8-10 hours. Is there anyway where I can keep the system load under control during the deletion. I tried using nice -n19 rm -rf * but that doesn't help in system load. P.S. I asked the same question on superuser.com but didn't get a good enough answer so trying here.

• Picasa v.3.6.2 for Mac is suddenly very slow - what are the implications of rebuilding my database?

  - by 3rdparty

  Recently Picasa v3.6.2 for Mac has become very sluggish - mainly noticable for any (non destructive) changes made to photos such as starring an image. This action used to be nearly immediate, but recently I've found it can take 1-3 seconds for Picasa to register the change, and become responsive again. I'm considering rebuilding my Picasa database as per these instructions - however I'm concerned I may lose any pre-existing non-destructive (unsaved) edits, along with Picasa albums that I have created. Curious if anyone has experienced Picasa sluggishness with the latest version and/or what their results have been from rebuilding their database. My last resort is to SuperDuper my drive and then rebuild the database, so I can always restore it if I lose critical data.
