Hey everyone, Is anybody aware of a /true/ active/active multi-head and multi-target clustered iSCSI daemon? IE: Server 1: Hostname: host1.test.com IP Address: 10.0.0.1 Server 2: Hostname: host2.test.com IP Address: 10.0.0.2 Then they would utilize a CLVM disk between them, let's call that VG "disk" and then directly map each LUN (1,2,3,4,etc) to LV's named 1,2,3,4,... and

Hello, Currently The CentOS project publishes errata on its CentOS Announce mailing list. In order to import this into a package management system (like Katello on The Foreman), one needs to parse the mailing list and convert it into XML before importing it. This is done to some extent on http://cefs.steve-meier.de/ but some more legwork needs to be done before The Foreman can understand the

OK, so I did an upgrade to PHP 5.3 on one of my servers. I noticed the uninstall of php also removed SquirrelMail and it won't install under PHP 5.3. Has anybody worked this out with a good RPM or repo solution? -- John Hinton 877-777-1407 ext 502 http://www.ew3d.com Comprehensive Online Solutions

I am not sure how to correctly troubleshoot this. I just noticed that my /var/log/xferlog file is huge. There are no files in /etc/logrotate.d/ for xferlog. This is what leads me to believe that it isnot rotating. Or perhaps I do not have it set to rotate. I am not sure. I am running CentOS release 5 (Final). Can someone tell me what I, apparently, do not have configured correctly. Thank

Hey guys, Need an opinion on what to use for file versioning text conf files that get updated by scheduled rsync's etc. Need something that can watch the file, so it doesn't need an explicit checkin, and can be diffed by a web front end. I haven't any preference on backend either. Thanks for any suggestions, jlc

I've updated my kickstart configuration files to work with CentOS 6 and am most of the way there integrating a CentOS 6 system into our LDAP/NIS environment.

Hi all, When I am installing I use kickstart and have a line like: repo --name=Updates --baseurl=http://192.168.1.14/centos/5.6/updates/x86_64/ and that works great for installing the OS. After that the machine reboots and I have it automatically go into additional installations running scripts. These installations do "yum install XXX". However, its no longer using my above repo

Does anybody know why this list is private and password protected? It would be nice to see progress, but it appears that part of the development is completely locked down and not open source. -- Steven Crothers steven.crothers at gmail.com

Hi all, A recent update to CentOS 5.9 has broken my cluster's ability to fence nodes. I have two Dell's which are both fenced via their DRAC6 cards. The current configuration in cluster.conf for the fencing devices is: <fencedevice agent="fence_drac5" cmd_prompt="admin1-&gt;" ipaddr="192.168.251.11" login="fencer" name="ms1-drac"

Hi all, on my nodes I have another cluster manager running that takes care of fencing the node, is it safe to disable ocfs2 self-fencing? Details: I'm using ocfs2 over drbd in master/master aka primary/primary mode. In case of loss of network connectivity I would like to disconnect the drbd device, invalidate it and unmount the filesystem but ocfs2 reboots the node.... Is it possible to

I have a CentOS 5.6 system (recently installed) that, for some reason, has decided to mangle one of its drives, specifically /dev/hde1 ... No errors anywhere, just rebooted the machine over the weekend and it's gone. Up till the reboot, the drive was fine, I was writing to it without a problem. fdisk tells me: ---------- # fdisk -l /dev/hde Disk /dev/hde: 160.0 GB, 160041885696

I have a CentOS-5.6 remote server in a house in Italy, where there are occasional thunder-storms. There was one yesterday, when the electricity went off 3 times, for a second or so on each occasion. My server, an HP MicroServer, came back (re-booted) on 2 of the 3 occasions, but not on the third. I assume that the problem arises because the machine does not close down properly. (Although it is

Hello everyone. I am currently working on setting up new servers for my employer. Basically we want two servers, all of them running several VEs (virtual environments, OpenVZ) which can dynamically take over each others job if necessary. Some services will run concurrently on both servers like apache2 (load balancing), so those need concurrent access to specific data. We had a close look at

Hi, instead of slicing and/or partitioning a drive one can also limit the capacity the drive reports the controller and OS. This is what oem''s do to ensure that drives from different manufacturers and revisions all have the same capacity. Different routes need to be followed for (S)ATA and SCSI/SAS drives, because of different command sets. I''ve no experience with setting the

I have 10 servers in a cluster running Debian Etch with 2.6.26-bpo.2 with a backport of ocfs2-tools-1.4.1-1 I'm using AoE to export the drives from a Debian Lenny server in the cluster. My problem is if I mount the ocfs2 partition on the server that is exporting it via AoE it fences the entire cluster. Looking at the logs exporting the ocfs2 partition doesn't give much information...
