similar to: Dovecot error on rhel 6.1 using GFS2(bug)

We have done some benchmarking tests using dovecot 2.0.12 to find the best shared filesystem for hosting many users, here I share with you the results, notice the bad perfomance of all the shared filesystems against the local storage. Is there any specific optimization/tunning on dovecot for use GFS2 on rhel6??, we have configured the director to make the user mailbox persistent in a node, we will

Hi, all this days I'm testing a dovecot setup using lvs, director and a cluster email backend with two nodes using rhel5 and gfs2. In the two nodes of the email backend I configured mail location this way: mail_location = sdbox:/var/vmail/%d/%3n/%n/sdbox:INDEX=/var/indexes/%d/%3n/%n /var/vmail is shared clustered filesystem with GFS2 shared by node1 and node2 /var/indexes is a local

Hello list, we continue our tests using Dovecot on a RHEL 6.1 Cluster Backend with GFS2, also we are using dovecot as a Director for user node persistence, everything was ok until we started stress testing the solution with imaptest, we had many deadlocks, cluster filesystems corruptions and hangs, specially in index filesystem, we have configured the backend as if they were on a NFS like setup

Today I will try Dovecot Director for a setup using a Cluster Backend with GFS2 on rhel5, my question is if is Director stable for use in production for large sites, I know is mainly designed for NFS but I believe it will do the job also for a cluster filesystem like GFS2 and should solve the mail persistence problem with a node and locking issues. I plan to add a layer behind a load balancer to

Hi to all in the list, we are trying to do some tests lab for a large scale mail system having this requirements: - Scale to maybe 1million users(Only for testing). - Server side filters. - User quotas. - High concurrency. - High performance and High Availability. We plan to test this using RHEL5 and maybe RHEL6. As a storage we are going to use an HP EVA 8400 FC(8 GB/s) We defined this

Centos CSGFS is at this time really outdated compared to current rh updates and fixes, is the centos team still giving support to this version???. Best regards

Hi people, I know I saw this at some point in the list but can't find it, I need a script wich monitor the health of the email backend and if a node fails remove it from the director server, once is up again add it, I plan tu run the script at the load balancer, if you have some let me know.. thank's in advance

Hi, I'm trying to put in place a KVM cluster (using clvm and gfs2), but I'm running into some issues with either sanlock or virtlockd. All virtual machines are handled via the cluster (in /etc/cluser/cluster.conf) but I want some kind of locking to be in place as extra security measurement. Sanlock ======= At first I tried sanlock, but it seems if one node goes down unexpectedly,

Just that, wich is the recommended quota backend for sdbox in terms of performance and flexibility running a setup of virtual users with ldap??... thank's in advance...

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

Ok, I'm experiencing slowness serving SAN-based GFS2 filesystems (of a specific SAN configuration). Here's my layout: I have a server cluster. OS= RHEL 5.4 (both nodes...) kernel= 2.6.18-194.11.3.el5 Samba= samba-3.0.33-3.14.el5 *On this cluster are 6 GFS2 Clustered filesystems. *4 of these volumes belong to one huge LUN (1.8 TB), spanning 8 disks. The other 2 remaining volumes are 1

I have tried sending this before, but it did not appear to get through. Hello, When using gfs2 with quotas on a SAN that is providing storage to two clustered systems running CentOS6.5, one of the systems can crash. This crash appears to be caused when a user tries to add something to a SAN disk when they have exceeded their quota on that disk. Sometimes a stack trace is produced in

libguestfs 1.6 will be the basis for RHEL 6.1. If you are using RHEL 6.0, thanks for supporting Red Hat, and if you want to try out the new version, then I have built some packages here: http://people.redhat.com/~rjones/rhel6.1-libguestfs-preview/ These are built on RHEL 6.0 and should install directly on top of RHEL 6.0. Some highlights: - Based on the upstream stable 1.6 branch. - Much

Hello, I will create a Xen cluster and using GFS2 (with conga, ...) to create a new Xen cluster. I know that GFS2 is prod ready since RHEL 5.3. Do you know whent Centos 5.3 will be ready ? Can I install my GFS2 FS with centos 5.2 and then "simply" upgrade to 5.3 without reinstallation ? Tx

Hi, I'm trying to get more performance out of my DRBD cluster with gfs2. It seems that our gfs2 implementation is quit slow.
