Kernel = 2.6.27.10
Parted = 1.8.8.git.2008.03.24-11.1
Can anyone help explain the problem here?
After a reboot:
p34:~# mount /dev/sda1 /r1
mount: you must specify the filesystem type
(from dmesg)
[ 75.325551] XFS: bad magic number
[ 75.325557] XFS: SB validate failed
p34:~# xfs_repair -n /dev/sda1
Phase 1 - find and verify superblock...
bad primary superblock - bad magic number !!!
attempting to find secondary superblock...

So I re-did what I did before the reboot, this time though I removed the
old partition and created a new one just as I did before.

Is this normal? Now everything is fine etc, how come this information is
not kept across reboots? Are partitions broken > 10T?

How come the information is 'lost' after a reboot?
I have done this same process with ext3 and no issues when the partition is
less than 6TiB, am I hitting some kind of bug here with parted or XFS?
Justin.
