Hi - I'm trying this process - adding a drive to a ZFS raidz pool. Am getting the following error...
cannot attach /dev/sdf1 to raidz1-0: can only attach to mirrors and top-level disks
This was a clean build on Unraid 7.0.1 just after release.
I thought this error was due to the previous ZFS 2.3 in ability to expand raidz and it was fixed as per the guide you linked in this thread. Am I doing something wrong?
