Re: Removing drives from system

[Kirk Goins <kirkgoins@xxxxxxxxx>]

Roger,

I don't believe you can do what you want to do with a failed raid set. I'm
pretty sure you will need to fix the failed drive/set then you could remove
the drive. I know that is not what you want to do.  The only thing I can
think of doing if you can't buy a drive ( Those drives should be dirt cheap
these days ), is to stop raid on another set, remove a drive from the ASP
and use it to replace the failed drive.

While replacing the failed drive and rebuilding raid can be done
concurrently, stopping raid5 requires a dedicated system.
