The host use UIT's CT1600 and UIT's 2000E IP-SAN storage (single LUN 10TB)
last time the switch got a power failure during the data backup (the iSCSI connection is lost)
after the iSCSI reconneted, the filesystem was unable to use.
So I try use fsck.gfs2 to fix the filesystem problem.but there is a error message and I got no idea with this error.
[root@Toureg ~]# fsck.gfs2 /dev/sdc
Initializing fsck
The system master directory seems to be destroyed.
Okay to rebuild it? (y/n)y
Trying to rebuild the master directory.

I had attached the host dmesg wish the data can come back.
the OS is RHEL 6.0 and I also tried CentOS 5.7 SL 6.1 the results are the same . only centos 5.4 will got different error messages
I guess it depends on what version of the gfs2-utils used.
btw:
gfs2_tool version
gfs2_tool master (built Nov 10 2011 21:26:03)
