lost xfs filesystem on md0

[james rich <james.rich@m.cc.utah.edu>]

Hi folks,
	I've got two old SCSI disks configured in a raid0 setup on
/dev/md0.  I had an unplanned power loss and now I get the following error
message:

scsi0: ERROR on channel 0, id 6, lun 0, CDB: Read (10) 00 00 00 00 38 00
00 08 00 
Info fld=0x3f, Current sd08:21: sense key Medium Error
 I/O error: dev 08:21, sector 31
I/O error in filesystem ("md(9,0)") meta-data dev 0x900 block 0x30:
    xfs_trans_read_buf

The filesystem completes the mount process but no files show up
(/var/spool is gone now :( ).  Does the above error indicate an error with
hardware or with xfs?  In either case, is there some way to recover the
contents of /dev/md0?
