Convert ZFS RAID0 to mirror and vice versa
·1 min
ZFS makes it so easy to convert striping to mirroring or vice versa:
# Assume "foo" already existed and "bar" is new
zpool attach spinning-rust /dev/disk/by-id/foo /dev/disk/by-id/bar
zpool detach spinning-rust /dev/disk/by-id/bar
No need to initialize the drives or anything - just pass the raw disks.
