Today our production database stopped working because
of ocfs2 1.4.1 bug..du -sch and df -h was showing different size on location
where archive logs are..so after searching on google, i realize we hit a bug with ocfs2
1.4.1. Here is the solution of fixing this problem;
first of all u need to umount ocfs2 partition using below command line;
umount /oradata1 (location where partition as ocfs2 is mounted)
then u need to run ;
/sbin/fsck.ocfs2
-fy /dev/sda1
it could take a
while to finish; u can break the operation while fixing..wont effect any
datafiles or system files on this partition...in case of losing any datafiles, better taking a fresh backup before running fsck.ocfs2.
