Is there any way to allocate/mark bad the badblocks with XFS so they
won't be used by the filesystem? SCSI drives usually have their own way
to do this internally in the defects list, but AFAIK EIDE drives do not.
Historically, XFS grew up on SCSI drives with the IRIX "fx" utility to
help add blocks to the drive's internal defect list, so I don't know if
there is a really user-friendly, automated way to add bad blocks to an
XFS filesystem on an EIDE drive.
The only way I can see to do it is with xfs_db and xfs_bmap, although
I'm not clear on the procedure.
