Re: RAID creation resync behaviors

Hannes,

quoted

It doesn't help me obtain the information I need to make a decision in
mdadm as whether to overwrite all or compare+write when resyncing a RAID
array.

What you actually want is the COMPARE AND WRITE SCSI command

Actually, I think what Jes needs is a MISCOMPARE AND WRITE command :)
