Support for add disk SCSI
by Luis campo 09 Sep '09

09 Sep '09

Dear Sirs. I have a ML370 G4 server with 2 disk SCSI Ultra 320 of 300 GB in RAID-1 through a controller and operating system CentOS 4.7. My question: CentOS 4.7 could support the expansion of capacity by adding 6 disks SCSI Ultra 320 of 300GB in Raid-1? Thanks for your reply Luis _________________________________________________________________ News, entertainment and everything you care about at Live.com.

SQL Server 2005 and CentOS?
by Rob Kampen 09 Sep '09

09 Sep '09

One of my clients use a software product that is "upgrading" and will shortly utilize micro$oft SQL server 2005. Currently the clients are XP on older machines with the database residing on a Samba / CentOS server and this works very well. Question: Does anyone run SQL server from XP in a virtualbox on CentOS? Any other configuration that works on a linux server? I do not want to have to buy another server grade machine just for this application. Thanks for your insight. Rob

UTC timezone not available in RHEL4
by Michael Dross 09 Sep '09

09 Sep '09

Hi all, I have been using Red Hat for a very long time and run CentOS 4 on some of my production servers. One of the things that has bugged me for a long time is the fact in the Time Zone configuration there is not a selection for UTC or GMT. As a work around I have been linking the /etc/localtime -> /usr/share/zoneinfo/UTC which works, but when Yum auto updates to a new version it resets the timezone back to EST. When this happens it messes up my timings in the crontab. Is there a reason UTC is missing a timezone selection in RHEL4? It is an option in RHEL5. Is there a better way to set the system to UTC then the /etc/localtime -> /usr/share/zoneinfo/UTC work around, and its problems?? Thanks, Mike

iwl4965 causes soft lockups
by Ryan Pugatch 09 Sep '09

09 Sep '09

Hi all, Annoying issue.. my ThinkPad T61 has an iwl4965 wireless card. When I have the wireless switch on, I experience a lot of issues.. system keeps freezing..unfreezing..freezing..etc. Sometimes, a soft lockup is logged to /var/log/messages. psmouse.c also sometimes throws an error saying the mouse lost synchronization. Obviously, this is causing the system to freeze for a sec and throws everything off. This is the case with both iwl4965-firmware ver 228.57.1.21 and 228.57.2.23. Any suggestions? I am not able to use my wifi :( Other info: CentOS 5.3 - 2.6.18-128.7.1.el5 (also happens with 2.6.18-128.el5) x86_64 Thanks in advance for any ideas. Ryan

pwconv with partial /etc/passwd
by Eugene Vilensky 08 Sep '09

08 Sep '09

If shadow passwords are already in use, and new entries are appended to /etc/passwd that include password hashes, is it still possible to use pwconv to generate /etc/shadow entries for just the few newly appended accounts? Regards, Eugene

3Ware 9650SE and XFS problems under Centos 5.3
by . . 08 Sep '09

08 Sep '09

Hello all, Came across my first real "problem" in all the years I've been using Linux today and I'm stumped for an answer. I've recently built a back-up server on top of Centos 5.3 using a 3Ware 9650SE 4 port SATA card and 4 x 1.5TB drives in a RAID 5 array. I went for the 3Ware card as it has driver support already so any kernel updates won't require me to rebuild the drivers each time. My current kernel is 2.6.18-128.2.1.el5 x86_x64. My problems started a few weeks ago with some message issues with the 3Ware card causing it to stop accessing the mounted RAID array. The only way to resolve it was a cold boot of the machine. Then today I log-in to discover the RAIDed partition has been auto un-mounted by XFS itself. So at this point I'm not sure where the problem lies. Is it the card that is faulty/problematic or is it something with the XFS file system? I'll take the XFS problem first as it's the most recent. When I logged in today I found the following in my server logs: Sep 7 21:08:19 backup kernel: XFS internal error XFS_WANT_CORRUPTED_GOTO at line 1561 of file /home/buildsvn/rpmbuild/BUILD/xfs-kmod-0.4/_kmod_build_/xfs_alloc.c.

I went with XFS as all the research I did indicated that it gave the best performance for the millions of small files in the backups we run and doesn't have any many issues with hardlinks as EXT3. - J _________________________________________________________________ Share your memories online with anyone you want. http://www.microsoft.com/middleeast/windows/windowslive/products/photos-sha…

sendmail routing
by Hugh E Cruickshank 08 Sep '09

08 Sep '09

CentOS 4.8, sendmail 8.13 Hi All: I have a couple of questions regarding the routing of outgoing emails. I have spent several hours doing Google searches but I have not come close to what I am looking for. If someone can give me push in the right direction I would greatly appreciate it. We currently have three domain names (two for our development company and one for our production company). We have one mail server in our development office that hosts all three domain names. Actually we just treat the three domain names as aliases of the mail server (via the local-host-names file and I do not see a need to change this. What I would like to do is route (relay?) any outgoing emails that are from emails addresses using only one of those domains to a separate SMPT server. 1. Is this possible? 2. What is it called? 3. Can you provide examples or links to relevant docs? TIA Regards, Hugh -- Hugh E Cruickshank, Forward Software, www.forward-software.com
