[Linux-cluster] gfs2.fsck bug

[yvette hirth]

hi,

our gfs2 datasets are down; when i try to do a mount i get:

[root at DBT1 ~]# mount -a
/sbin/mount.gfs2: node not a member of the default fence domain
/sbin/mount.gfs2: error mounting lockproto lock_dlm
/sbin/mount.gfs2: node not a member of the default fence domain
/sbin/mount.gfs2: error mounting lockproto lock_dlm
/sbin/mount.gfs2: node not a member of the default fence domain
/sbin/mount.gfs2: error mounting lockproto lock_dlm
/sbin/mount.gfs2: node not a member of the default fence domain
/sbin/mount.gfs2: error mounting lockproto lock_dlm
/sbin/mount.gfs2: node not a member of the default fence domain
/sbin/mount.gfs2: error mounting lockproto lock_dlm
/sbin/mount.gfs2: node not a member of the default fence domain
/sbin/mount.gfs2: error mounting lockproto lock_dlm

our cluster.conf is consistent across all devices (listed below).

so i thought an fsck would fix this, then i get:

[root at DBT1 ~]# fsck.gfs2 -fnp /dev/NEWvg/NEWlvTemp
(snippage)
RG #4909212 (0x4ae89c) free count inconsistent: is 16846 should be 17157
Resource group counts updated
Unlinked block 8639983 (0x83d5ef) bitmap fixed.
RG #8639976 (0x83d5e8) free count inconsistent: is 65411 should be 65412
Inode count inconsistent: is 20 should be 19
Resource group counts updated
Pass5 complete
The statfs file is wrong:

Current statfs values:
blocks:  43324224 (0x2951340)
free:    38433917 (0x24a747d)
dinodes: 21085 (0x525d)

Calculated statfs values:
blocks:  43324224 (0x2951340)
free:    38466752 (0x24af4c0)
dinodes: 21083 (0x525b)
The statfs file was fixed.

gfs2_fsck: bad write: Bad file descriptor on line 44 of file buf.c

i read in https://bugzilla.redhat.com/show_bug.cgi?id=457557 that there 
is some way of fixing this with gfs2_edit - are there docs available?

as we've been having fencing issues, i removed two servers (DBT2/DBT3) 
from the cluster fencing, and they are not active at this time.  would 
this cause the mount issues?

tia for any advice / guidance.
