Hi,

I am facing a problem when my servers get power cycled by force. When they come up, almost everytime when xfs filesystems are being mounted, I get a system panic.

It looks like what's described here:

https://bugzilla.redhat.com/show_bug.cgi?id=657166

But I am running RHEL 6.2 and 6.3 (2.6.32-279.el6.x86_64)

This is what my fstab entrys look like:

LABEL=/brick1 /brick1 xfs sunit=256,swidth=3328,noatime,nodiratime,logbufs=8,largeio,quota 0 0


# xfs_info /brick1
meta-data=/dev/sdb isize=256 agcount=24, agsize=268435200 blks
         =                       sectsz=512   attr=2
data     =                       bsize=4096   blocks=6347161600, imaxpct=5
         =                       sunit=32     swidth=416 blks
naming   =version 2              bsize=4096   ascii-ci=0
log      =internal               bsize=4096   blocks=521728, version=2
         =                       sectsz=512   sunit=8 blks, lazy-count=1
realtime =none                   extsz=4096   blocks=0, rtextents=0


Even if I go to single user mode and try to mount (via the fstab entry), I get the panic. But I can mount it without any option by doing "mount /dev/sdb /brick1".

Is there any workaround to this?

Thanks,
...
