Hi,<br>
<br>
We just had failed OCFS2 file system, which was not fixed by running
fsck.ocfs2. It was still possible to read from it, so I have setup new
RAID10 formated using OCFS2 and copied all files to it. However,
because we have 1.7 milion files, it took a lot of time to copy 'em.
Original OCFS2 was created on top of RAID10 and with DRBD between.
However, DRBD copy didn't help much because it was corrupted too.<br>
<br>
Does anyone have suggestion on how to setup real-time, or near
real-time, hot space backup, which would have independent copy all
files. In case primary OCFS2 becomes unavailable or corrupted, this hot
spare copy would be used without much delay. We would just change iSCSI
initiators to use it as target, and cluster would be back up.<br>
<br>
In old days, we use small program called lsyncd. It detects changes
in file system, and does rsync of changed files/directories to remote
location. Is there any more advanced program/solution I can use with
OCFS2? Running rsync with number of files we have is too slow and can
be used only for daily backups.<br>
<br>
Thanks,<br>
Nikola<br>
