This is a common problem with old adaptec RAID controllers. Don't do
any IO while it's rebuilding, else it may corrupt data. After rebuild
is complete, the volume will probably be easily repairable.
DON'T DO ANYTHING UNTIL REBUILD IS COMPLETE. Particularly don't try
running xfs_repair.
Afterwards, install the very latest firmware for the controller, go in
"Serial select" utility in BIOS and deactivate Disk write cache (this
is the individual disks write caching). It will (mostly) avoid the
problem in the future.
