Dear list,
I would like to swap out a drive in a RAID6 (4 drives), but ideally
without letting the RAID degrade. I was thinking that it should be
possible to declare the new disk a copy of the old one, let it sync,
then remove the old one and let the new one take over, but MD does
not seem to support that.
If you can stop the array it can be done. Otherwise you will have to
degrade it while replacing
Replacing without degrade:
- stop the raid
- do a dd from old disk to new disk
- replace the disk
- re-start the raid
Cheers,
Rudy
