Hello list I've installed cluster suite with 8 physical nodes, these are connected to a SAN using CLVM and AOE protocol. The cluster suite runs on the physical nodes/servers, in dom0. If I have to use GFS, where do I install this? What is the right approach to using GFS with Xen. I see 2 options: 1. I install GFS inside each domU (unprivileged domain, the actual VM). 2. I install GFS on

Hello All, We are using Dovecot 1.1.3 to serve IMAP on a pair of clustered Postfix servers which share a fiber array via the GFS clustered filesystem. This all works very well for the most part, with the exception that certain operations are so inefficient on GFS that they generate significant I/O load and hurt performance. We are using the Maildir format on disk. We're also using

Hi all, If you have had experience hosting GFS/GFS2 on CentOS machines could you share you general impression on it? Was it realiable? Fast? Any issues or concerns? Also, how feasible is it to start it on just one machine and then grow it out if necessary? Thanks. Boris.

I am doing research on getting an operational GFS setup on 3 servers I have centos 4.4/64 built on. I can of course upgrade the to 4.5, but is it smarter to try centos 5 for this or can I get away with getting this working on 4.4/4.5? (basically trying to eliminate the need to visit the colo.) -krb

Hello list, I want to use shared volumes between severall vm''s and defenetly don''t want to use NFS or Samba! So i have three options: 1. simulated(software-) iscsi 2. GFS 3. OCFS2 What do you suggest and why? Kind regards, Florian ********************************************************************************************** IMPORTANT: The contents of this email and any

Hi David, Also consider using the mount option to specify backup server via 'backupvolfile-server=server2:server3' (you can define more but I don't thing replica volumes greater that 3 are usefull (maybe in some special cases). In such way, when the primary is lost, your client can reach a backup one without disruption. P.S.: Client may 'hang' - if the primary server got

Hi Is there any way to re-export an nfs mounted directory?

Hi, I have configured two machines for testing gfs filesystems. They are attached to a iscsi device and centos versions are: CentOS release 5.4 (Final) Linux node1.fib.upc.es 2.6.18-164.el5 #1 SMP Thu Sep 3 03:33:56 EDT 2009 i686 i686 i386 GNU/Linux The problem is if I try to mount a gfs partition it hangs.

Hi list, I setup on 2 Xen Dom0s drbd/gfs a logical volume, this works as primary/primary so both DomUs will be able to write on them at the same time. But I dont know how to mount them from my domUs, I can see them with fdisk -l. The partition is /dev/xvdb1 SHould I install gfs on domUs and mount them on each as gfs partitions? [root@p3x0501 ~]# fdisk -l Disk /dev/xvda: 5368 MB, 5368709120

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, Sorry for repeating same mail ,while composing that mail i mistakenly typed the send button.I am facing problem with my gfs and below is the running setup. My setup Two node Cluster[only to create shared gfs file system] with manual fencing running on centos 4 update 5 for oracle apps. Shared gfs partition are mounted on both the node[active-active] Whenever i type df -h command it

On CentOS 5, the current centosplus kernel doesn't want to play with the kmod-gfs package (because kmod-gfs wants the stock kernel): # yum install kmod-gfs gives me: Transaction Check Error: package kernel-2.6.18-8.1.14.el5.centos.plus (which is newer than kernel-2.6.18-8.1.14.el5) is already installed Should it work, or is there a separate centosplus build that I've not

Hey All, I have a cluster setup and exporting gfs storage everything is working ok(as far as I know anyway). But instead of mounting the gfs storage I want the xen guest to be installed on the shared gfs storage. But with my current setup when I install the domU on the gfs storage it changes it to ext3. Is it possible this way or does the domU have to be on an ext file system?

Are the RPMs for the latest GFS kernel module GFS-kernel-2.6.9-72.2.0.8 to be used with the version 2.6.9-55.0.9.EL available ? I tried to compile the Source RPMs available from the Red Hat site but the modules can't be loaded because of invalid module format arising from version magic issues. The syslog shows: node0 kernel: gfs: version magic '2.6.9-55.0.9.ELsmp SMP 686 REGPARM

Hi all, Since I've got no reply on redhat cluster list, I'm trying here ... I'm testing a rhcs4 cluster with gfs. I noticed some poor performance while tarring data from a gfs volume to a local disk from both nodes at the same time, so I deceided to have a closer look. Here are the bonnie++ results: http://jure.pecar.org/gfs/ I don't know what to think of these ... but I doubt

Hello there! I made Debian, Xen 2.0 and CLUSTER/GFS work together :). I wrote this little tutorial to help you setup yours. Any feedback is welcome, except comments about W3C validation of my code :p Note that I am talking about compiling CLUSTER with your XEN kernel, I don''t explain how to setup a working cluster. You can find how to setup those in official RedHat docs. You will see,

Hi guys, I'm looking at the possibility of running a pair of servers with Dovecot LDA/imap/pop3 using internal drives with DRBD and GFS (or other clustered FS) for the mail storage and ext3 for the root drive. I'm currently using maildrop for delivery and Dovecot imap/pop3 with the stores over NFS. I'm looking for better performance but still keeping the HA element I have now with

This is the 2nd time this has happened to me. There was a kernel release over the weekend to .67.0.15, yet, they did not release the updated GFS to go along with it, so when the machine rebooted, there was no gfs file system in the new running kernel which in turn wreaked havoc on my cluster. I truly wish they would not do that :). I guess I shall have to not allow automatic yum updates from

Hello, I have a storage offering some 11 TB of space. I'd happily use ext3 and NFS export to 4 client machines, but 8 TB seems to be the tested maximum. I'd really like one mount point for the whole 11 TB. Since GFS offers lock_nolock option for local mounting, I'm assuming it's not so out of line to NFS export this GFS mount point. Thoughts and inputs appreciated. --Koji
