[Ocfs2-users] Faster backup (rsync)

  Hello,   I have 3 servers setup in following way: Two servers (server1 and server2) are connected using DRBD, which is used as volume for shared storage. This shared storage is formated using OCFS2. Server1 has RAID10, while server2 has RAID1 under DRBD. All three servers are acc

  Hello,   I'm running 3 server cluster based on DRBD/iSCSI/OCFS2 technologies. Two servers are connected using DRBD. One of these two servers is set to be iSCSI target, while all three servers access shared storage as iSCSI initiators. Shared storage uses OCFS2. For cluster communication pri

t oops or panic. Maybe it's too early to conclude that this BUG was finally fixed by this kernel, but error would usually manifest once every 7 days on one of 3 servers we have in cluster.   Hopefully this will help OCFS2 users on Centos5.5 that might have similar problem as we did.   Best Regar

[Ocfs2-users] Upgrading from OCFS2 1.4 to 1.6

  Hi all,   Do I need to run any upgrade (conversion) on OCFS2 1.4 file system after nodes have been updated to OCFS2 1.6? I see that it works without any conversion, but I'm not sure if new 1.6 features are available without some conversion?   Thanks,   Nikola __

[Ocfs2-users] OCFS2 and CLVM

  Hello,   I installed OCFS2 today on CentOS5.5 and the first impressions on performance are very good. Initially I used GFS2 on the cluster with 3 nodes. Since RedHat cluster is installed, I use CLVM. One of logical volumes created using CLVM is formated using OCFS2 and it works well for now
