I have a 4 node RAC cluster that had all 4 nodes crash. The systems
locked up.
Everytime I tried to bring up a box, it hung. So I commented out all the
ocfs2 volumes from the fstab file and the system booted fine.
I have 3 volumes that were in use at the time and 3 volumes that have
were unmounted. After booting, I see even though no volumes are mounted
(commented out of the fstab), I can see that it THINKS they are!
#mounted.ocfs2 -f
Device FS Nodes
/dev/sde1 ocfs2 appsdb1
/dev/sdf1 ocfs2 appsdb3
/dev/sdg1 ocfs2 appsdb3
/dev/sdh1 ocfs2 Not mounted
/dev/sdi1 ocfs2 Not mounted
/dev/sdj1 ocfs2 Not mounted
I set o2cb and ocfs2 NOT to start on boot up on all 4 nodes and
rebooted. After the reboot it looks like the volumes think they are
still in use by node 0 and 2.
#mounted.ocfs2 -f
Device FS Nodes
/dev/sde1 ocfs2 0
/dev/sdf1 ocfs2 2
/dev/sdg1 ocfs2 2
/dev/sdh1 ocfs2 Not mounted
/dev/sdi1 ocfs2 Not mounted
/dev/sdj1 ocfs2 Not mounted
I started o2cb and fsck.ocfs2 one of the volumes
#fsck.ocfs2 /dev/sde1
Checking OCFS2 filesystem in /dev/sde1:
label: st_dbf1
uuid: 08 dd 84 44 da 6e 4e 7e 80 a0 82 2f fd 80 de c0
number of blocks: 131070208
bytes per block: 4096
number of clusters: 511993
bytes per cluster: 1048576
max slots: 4
/dev/sde1 is clean. It will be checked after 20 additional mounts.
Where should I be looking here?
