Re: [zfs-discuss] ZFS pool replace single disk with raidz
To: ZFS Developers. I know we hate them but an "Are you sure?" may have helped here, and may be a quicker fix than waiting for 4852783 (just thinking out loud here). Could the zfs command have worked out c5d0 was a single disk and attaching it to the pool would have been dumb? Ryan Hirsch wrote: I have a zpool named rtank.

It already does this, and has for some time. # zpool create zwimming raidz /dev/ramdisk/rd1 /dev/ramdisk/rd2 /dev/ ramdisk/rd3 # zpool add zwimming /dev/ramdisk/rd4 invalid vdev specification use '-f' to override the following errors: mismatched replication level: pool uses raidz and new vdev is disk Which basically prompts someone to add the -f See also the first great debate on zfs-discuss. -- richard Ryan Hirsch wrote: I have a zpool named rtank.
