I have a pile of aging Dell MD-1000's laying around that have been replaced by new primary storage. I've been thinking of using them to create some archive/backup storage for my primary ZFS systems.
Unfortunately they do not all contain identical drives. Some of the older MD-1000's have 15x500GB drives, some have all 750's some all 1TB's. Since size and integrity matters here, not speed. I was thinking of creating one large pool containing multiple RAIDZ2's. Each RAIDZ2 would be one MD-1000 and would have 14 drives, reserving one drive per shelf as a spare. The question is: The final pool would have spares of 500GB, 750GB and 1TB. Is ZFS smart enough to pick the right one if a drive fails? If not, is there a way to make this scenario work and still combine all available storage in a single pool?
