[Ocfs2-users] ocfs volumes corrupt?

[Kendall, Kim]

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?
