I thought it might have been just a bad raid5 when I built it after the install so I re-installed it. Same problem
fsck.ext3: Invalid argument while trying to open /dev/md2 /dev/md2: The superblock could not be read or does not describe a correct ext2 filesystem. If the device is valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate superblock: e2fsck -b 8193 <device>
Any ideas? Both md0/md1 boot fine and they are raid1's is there something about raid5 the xen kernel might not like?

This is likely to be the problem!
If you boot to single-user mode and manually "modprobe raid5" to load the raid5 personality, can you see the array?

Adding init=1 to the xen/kernel line only allows it to go so far before it just reboots it self, not far enough for me to even hit I or do anything else.
If I comment out the raid5 /dev/md2 /home in /etc/fstab the xen kernel boots
lsmod | grep raid raid1 24769 2 # modprobe raid5 FATAL: Error inserting raid5 (/lib/modules/2.6.15- 1.1955_FC5hypervisor/kernel/drivers/md/raid5.ko): Unknown symbol in module, or unknown parameter (see dmesg)
# dmesg | grep raid5 raid5: automatically using best checksumming function: pIII_sse raid5: Unknown symbol xor_block raid5: Unknown symbol xor_block raid5: Unknown symbol xor_block
Should I report a bug on this?

It's probably down to an SSE oops in the raid5 module. I'm not seeing it on x86_64 but it seems still there on i386.
Should I report a bug on this?
