I'm trying to expand my zfs pool named myzfs from 3 to 4. After adding a undefined drive of the same size to the 4th slot in the pool and hitting start I get:
Wrong Pool State
myzfs - invalid expansion
Unraid version: Version: 6.12.0-rc6
File system type for pool is:
zfs, raidz, 1 group of 3 devices
Logs show:
May 31 12:15:34 sponge emhttpd: import 30 cache device: (sdb) VMware_Virtual_SATA_Hard_Drive_00000000000000000001

May 31 12:15:34 sponge emhttpd: myzfs: invalid expansion: not multiple of 3
Device count in pool config is greyed out - not changable.
Am I missing something? What is the procedure to expand ZFS from 3 > 4?
Thanks!
