I've been reading through the documentation on ZFS, and was hoping I could get some clarification and make sure I'm reading everything right.
I'm looking to build a NAS box, using sata drives in a double parity configuration (i.e. raidz2). This is mainly for warehousing large video files, so access speed and IOPS aren't terribly critical. I won't immediately need all 15 drives online, so what I would like to do is be able to resize the raid array. Is there any way to resize with ZFS? Or would the only way to do this be to make one raidz2 with 7 drives, and then when I need to expand make another raidz2 in the same pool. Obviously having two virtual devices in the pool means losing 4 drives to parity instead of just two. ie start out with zpool create tank raidz2 c1t1d0 c1t2d0 c1t3d0 c1t4d0 c2t1d0 c2t2d0 c2t3d0 and when i'm ready to expand use zpool add tank raidz2 c2t4d0 c3t1d0 c3t2d0 c3t3d0 c3t4d0 c4t1d0 c4t2d0 c4t3d0 Any and all comments are appreciated.
