similar to: Is Dovecot Director stable for production??

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

Centos CSGFS is at this time really outdated compared to current rh updates and fixes, is the centos team still giving support to this version???.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

Hi list, I've been trying to update my csgfs stuff to 4.7 this week but I notice that current csgfs is built against kernel-2.6.9-78.0.1 and is required as a dependence, right now current kernel is 2.6.9-78.0.5 it would be great if csgfs can be rebuilt or updated to this, so dependences works ok??? Best regards

Hi list, any timeframe for the sync of csgfs in centos 4 with current kernel updates???. Best regards

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 people, I have a setup configured using ldap, I have noticed that after a period of user inactivity if a client open connections to dovecot first attemps fails with this: Nov 16 19:34:43 cl05-02 dovecot: auth: Error: ldap(user at xxx.xx.xx,172.29.13.26): Connection appears to be hanging, reconnecting After the connections to ldap has been restablished everything starts working ok, is this a

I'm having a problem with dovecot ldap connection when ldap server is in another firewall zone, firewall kills the ldap connection after a determined period of inactivity, this is good from the firewall point of view but is bad for dovecot because it never knows the connections has been dropped, this creates longs timeouts in dovecot and finally it reconnects, meanwhile many users fails to

Hi, just to let you know to all the people testing dovecot in a RHEL 6.1 setup where nodes are Active/Active and sharing a GFS2 filesystem that there is a bug on latest rhel6.1 GFS2 kernel modules, and latest updates in 6.0 wich makes dovecot crash a GFS2 filesystem, with a corruption and other related errors, redhat people have posted a fix for the kernel wich is in QA:

Hi all, I want to know whether any other company and production use the ocfs2 ? Thanks. Jensen 2014.8.12

I'm searching for the SRPM corresponding to this installed RPM. % yum list | grep gfs2 gfs2-kmod-debuginfo.x86_64 1.92-1.1.el5_2.2 It is missing from: http://msync.centos.org/centos-5/5/os/SRPMS/ What I need from the SRPM are the patches. I'm working through some issues using the source code, and the patches in the RedHat SRPM

Hi. The short story... Rush job, never done clustered file systems before, vlan didn't support multicast. Thus I ended up with drbd working ok between the two servers but cman / gfs2 not working, resulting in what was meant to be a drbd primary/primary cluster being a primary/secondary cluster until the vlan could be fixed with gfs only mounted on the one server. I got the single server

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

Hi everybody, I have tested CTDB+GFS2+CMAN under Debian. It works good but I do not understand some points. It is possible to run the CTDB defining it under services section in cluster.conf but running it on the second node shuts down the process at the first one. My CTDB configuration implies 2 active-active nodes. Does CTDB care if the node starts with clean_start="0" or
