I'm running XFS on Mandrake 10.0 (2.6.3 kernel).
Please repdoruce with a current kernel. MD in early 2.6 kernels has

I took this opportunity to install Mandrake 10.1 which uses a 2.6.8 kernel.
I told the installer to reformat /dev/md0 but not to reformat /dev/md1
(/home).
NOTE: I did _not_ recreate any partitions or raidsets, and the installer
detected the raid partitions just fine.
During the following system boot, mounting md1 fails with a bunch of
messages in dmesg:

/home appears to be mounted according to /etc/mtab and 'mount', but I
get an I/O error when I try and ls /home.
If I unmount /home, then remount it I get the following in dmesg:

Ending XFS recovery on filesystem: md1 (dev: md1)
The filesystem appears to be mounted and I can see files/directories in
/home as I expect to see.
Doing 'find /home' gives the following in dmesg, although it appears to
complete the command:

What should I be doing now?
Is it safe to copy data off of this partition (should I mount read-only
to be safe?)
Regards,
Mark.
