Hello, I have 3 servers setup in following way:
Here finally comes my question. Do you think it's safe to mount OCFS2 in this way, since changes will happen from other nodes which will not be in cluster with backup process? Read-only mount, if possible, would prevent changes to go from backup process to live nodes. However, I assume file system might become corrupted for backup side? Is there flush method of some kind that I can initiate on all three servers or iSCSI target, before making snapshot on server2 and mounting OCFS2 in read-only and/or local mode? Does anyone have suggestion on how to make efficient backups of many files? DRBD is nice backup feature, but corruption in file system is distributed to both drives. Having separate file system copy is safe, even when it's not real-time. Did anyone try using lscynd with OCFS2? Lsync2 monitors changes in file system using inotify and transfers only changed folder to backup server using rsync. I was reading that inotify works with delay with OCFS2 when changes happen on remote node. However, few seconds delay is not problem for me. Thanks, Nikola |
