Recover botched drdb gfs2 setup .
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 working and left to for the contractor to do there bit. Two months down the line and a few o...

gfs2 and quotas - system crash
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 /var/log...

DRBD,GFS2 and GNBD without all clustered cman stuff
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 perfect as cat /proc/drbd Server 2: LogVol09, Secondary for /d...

sanlockd, virtlock and GFS2
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 nod...

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

CTDB+GFS2+CMAN. clean_start="0" or clean_start="1"?
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...

GFS2 hangs after one node going down
Hi guys, my goal is to create a reliable virtualization environment using CentOS 6.4 and KVM, I've three nodes and a clustered GFS2. The enviroment is up and working, but I'm worry for the reliability, if I turn the network interface down on one node to simulate a crash (for example on the node "node6.blade"): 1) GFS2 hangs (processes go in D state) until node6.blade get fenced 2) not only node6.blade get fenc...

Local node indexes in a cluster backend with GFS2
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 filesystem at the node, so each node has...

Dovecot tuning for GFS2
Hello, I'm deploing a new email cluster using Dovecot over GFS2. Actually I'm using courier over GFS. Actually I'm testing Dovecot with these parameters: mmap_disable = yes mail_fsync = always mail_nfs_storage = yes mail_nfs_index = yes lock_method = fcntl Are they correct? RedHat GFS support mmap, so is it better to enable it or leave it disabled?...

Corrupted mboxes with v2.2.4, posix_fallocate and GFS2
Hi, on a clustered Dovecot server installation that was recently moved from a shared GPFS filesystem to GFS2, occasional corruptions in the users' INBOXes started appearing, where a new incoming message would be appended directly after a block of NUL bytes, and be scanned by dovecot as being glued to the preceding message. I traced this to the file extension operation performed in mbox_sync_handle_e...

Dovecot imaptest on RHEL4/GFS1, RHEL6/GFS2, NFS and local storage results
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 thank's any help from you. we are interested in using GFS2 or NFS, we believe the problem is the locks, how can we improve this?? best regards, Aliet The results rhel 4.8 x86_64/GFS1 two nodes...
