Hi,

Yesterday I reformatted my two XFS pools (bigcache and camcache) to ZFS and then copied my data back onto them. The reason for this was that I wanted to add another disk to each pool.

Now, when I try to create a ZFS pool with two slots and add the two disks, the second disk is ejected when the array starts. It then shows up under unassigned devices with no error message.

The new disks are connected to a new controller with an Asmedia1064 chipset. Could this be the cause of the problem?

i use Unraid 7

Please post the diagnostics after attempting to create the pool.
