[Linux-cluster] Problems with gfs_grow

Hello all,

I tried to expand my gfs filesystem from 1,5TB to 2TB. I added the new 500G
disk to volume manager etc, and finally run gfs_grow. The command finished
without warnings, but a few seconds after that my cluster crashed with
"Kernel Panic - not syncing. Fatal exception". When I got the cluster up
again and executed gfs_fsck on the filesystem I get this error:

sh-3.1# gfs_fsck -v /dev/xxx-vg/xxx-lv
Initializing fsck
Initializing lists...
Initializing special inodes...
Validating Resource Group index.
Level 1 check.
5167 resource groups found.
Setting block ranges...
Can't seek to last block in file system: 4738147774
Unable to determine the boundaries of the file system.
Freeing buffers.

What could be the problem?



Info on the system:

CentOS 5.1

sh-3.1# rpm -qa |grep gfs
