Hi all, I've running a CentOS 5 64bit server that hosts VMware Server and uses authentication via Samba/Winbind. The problem is that authentication in the VMware Server web interface does not work because apparently it is a 32bit application and CentOS 5 x86_64 provides only a 64bit version of the pam_winbind.so library. At least that what I conduct from the following message I get in

Hello all, In the network there is already a W2K server serving as DHCP server for the network. Then we want to implement LTSP, so we need to setup another DHCP server, right? Due to unexpected reason (little by little migration of w98 clients to LTSP), we need to keep the W2K server running in that network. Can we then have 2 DHCP server in the same subnet, only serving pre-determine clients

Hi everybody, after upgrading a few CentOS machines from 5.0 to 5.2, and during that upgrading rsync from 3.0.0-1.el5.rf to 3.0.3-1.el5.rf (both from rpmforge) rsync stopped working and bails out with a segfault after some undeterministic time (zero to a few seconds) during a sync. Manually going back to 3.0.2-1.el5.rf seems to work. Has anybody experienced similar problems? I'm not sure if

I am considering building a pair of storage servers that will be using CentOS and GFS to share the storage from a Coraid (SATA+Raid) EtherDrive shelf. Has anyone else tried such a setup? Is GFS stable enough to use in a production environment? There is a build of GFS 6.1 at http://rpm.karan.org/el4/csgfs/. Has anyone used this? Is it stable? Will I run into any problems if I use CentOS 3.5

Hi all, I am using heartbeat and drbd on CentOS 5 (see http://www.centos.org/modules/newbb/viewtopic.php?topic_id=7816&forum=41 for details).. DRBD and heartbeat are working, and now I want to put GNBD on top on this. However, I installed the latest CentOS-plus kernel (2.6.18-8.1.8.el5.centos.plus) but there doesn't appear to be a kmod-gndb for this kernel. Looks like the latest

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Up until now, I have been using drbd for file custers with great success. Yes, it is a PITA, and sometimes you can get annoying sincronization issues (mostly on lab situations). Now I have been considering giving gnbd (with cs/gfs) a try. Do any of you ever crossed this path ? Any comparisons or comments ? TIA, - -- Rodrigo Barbosa "Quid

Hi all, Where i want to arrive: 1) having two storage server replicating partition with DRBD 2) exporting via GNBD from the primary server the drbd with GFS2 3) inporting the GNBD on some nodes and mount it with GFS2 Assuming no logical error are done in the last points logic this is the situation: Server 1: LogVol09, DRDB configured as /dev/drbd0 replicated to Server 2. DRBD seems to work

Hello, As a Virtuozzo users we have majority of our diskspace formatted with -i 1024 -b 1024. Lately I discovered that on CentOS 4.6 ext2online barfs when I try to grow such filesystem. Running it with -v -d, it prints lots of lines like: ext2online v1.1.18 - 2001/03/18 for EXT2FS 0.5b ext2online: 873646830 is a bad size for an ext2 fs! rounding down to 873644033 ... group NNN inode table has

Hi all I tried to run bonnie++ disk stresser in dom-U, who''s disk is backed with non-local (on nfs) loop-back file. The machine rebooted pretty quickly. So, how do I tell what''s barfing? Is it Xen? Is it dom-0 (nfs or loop-back)? I looked in dom-0''s /var/log/messages and didn''t see any obvious record of a dom-0 whoopsie (but is that the right place to look

Hi all, We're looking at deploying a small Xen cluster to run some of our smaller applications. I'm curious to get the lists opinions and advice on what's needed. The plan at the moment is to have two or three servers running as the Xen dom0 hosts and two servers running as storage servers. As we're trying to do this on a small scale, there is no means to hook the

Hi all, I was informed[1] that gfs & rhcs packages are in the works but that there are some problems with the code. What are these problems? Can we do anything to help test / solve them?

Hi all, Man page of tune2fs says that max journal size is 102,400 filesystem blocks, which translates to ~100MB with 1kb blocks or ~400MB with 4kb block. I wonder - why this limitation exists? Now that relatively cheap ssd devices exist (gigabyte iRam) that offer up to 4GB of space, it would be extremely useful to use whole capacity of such device for full data journaling. -- Jure Pe?ar

Hey all, I''m thinking about moving my 2.0.7 install over to 3.0.0 for eventual use in a production environment. Two questions: 1) Do people think 3.0.0 is ready for production - or is it just a testing/unstable playpen? 2) What do I have to change - just the xen-2.0.7.gz for do I have to recompile the dom0/domU kernels too?

Hello, I just noticed that centosplus for c4 provides mysql 5.0.54, while centosplus for c5 does not provide that recent version and so c5 is stuck with mysql 5.0.22. Any particular reason for that or it is just that no one has yet compiled & packaged 5.0.5x for c5? Also, where does 5.0.54 comes from? MySQL site is only at 5.0.45 rpm and 5.0.51 source ... -- Jure Pe?ar

Hello, I seem to recall from my redhat5/6/7 days that certain installation methods used for kickstarting only invoked text mode install. Now I read that graphical install is default in kickstart on el5/6. However, in my test environment (with older HP DL140G3) I only get text mode install up, even if I specify graphical in kickstart file, with both nfs and http install methods. There's no

Hi everybody, as discussed and agreed at the Cluster Summit we need to split our tree to make life easier in the long run (etc. etc.). We need to decide how we want to do it and there are different approaches to that. I was able to think of 3. There might be more and I might not have taken everything into consideration so comments and ideas are welcome. At this point we haven't really

Hi list, I'm configuring microsoft doc|ppt|xls viewers to run under KDE. After a bit of hassle even printig works ok :) Great work, guys.

Hi all, I'm debugging a performance problem for a client. Needless to say, the organisation of their data is such that this problem is really annoying. Here's the situation: Samba 3.0.x PDC in a mixed 9x/nt/xp environment, using acls. When trying to delete a large number of folders from a folder, the 'preparing to delete' stage takes about half hour. It's simple to repeat:
