Hello There,

 

I recently upgraded my Unraid system from 6.11.5 to 6.12.3 and now I'm encountering issues with my pre-existing ZFS pool.

 

I followed the steps posted here:

 

Next assign all the devices to the new pool. Upon array Start the pool should be recognized, though certain zpool topologies may not be recognized (please report).

 

I tried to make a new pool with my zfs devices in several different ways, i tried "filesystem auto" and "filesystem zfs" in different configurations.

Unraid tells in every tried configuration: "Unmountable: Unsupported or no file system"

 

After I got my hearbeat back to normal I tried to import the ZFS pool using the command "zfs import ...".

Now the zpool shows up in the ZFS Master Plugin and i can access my data, but all discs are "unassigned devices".

 

I have a raidz2 with 5 hdd and a sdd as a cache disc.

I do not think that is how zfs in 6.12 is supposed to work.

So maybe this is one of the currently not recognized topologies?

 

Any insights or suggestions would be greatly appreciated. Thank you!

 

Kind regards

Max

main problem solved, new problem not part of original post

You pool has a cache vdev, so that device needs to be assigned with the rest of the pool:

 

export the pool first

create a new pool with 6 slots

assign the disks first then the NVMe device in the last slot

leave the pool filesystem set to auto

start array

Thanks JorgeB! I was missing the export before starting the array. The zpool show now up!

I can not access my data anymore, because the mountpoint changed. i have to figure out how to configure this that it works like before.
