May 9, 20233 yr Hey Guys, been a silent reader for a long time now. Thanks for all the Support! But Today, I need some help from the swarm After Upgrading to Unraid 6.12.0-rc5 i decided to completely redesign my Disklayout. So i bought some new 18 TB drives, set up a ZFS (Encrypted) pool and copied stuff over. Everything went fine and was running smothly. Array now contains only 1 single USB-Drive. Today my new NVMe Cachedrives arrived. So I installed them and tried to set up my chache pool. After doing that i also added my "old" 10TB WD RED drives as a new vdisk to the ZFS-Pool. I did that via command line because it seemed like the GUI can't handle such Things at the Moment. No we are whre my Problems began. Array refused to come up, always telling me something "Unmountable Filesystem" (also for the ZFS-Pool but this was accessible anyway). After some digging around I tried to Reset the Array config ( Tools -> New Config ) I only ticked "Array" but it resettet everything. And now thinks are totally f*cked up. ( see Screenshot ). I reassigned all Drives as they where, but no real luck. I could the ZFS Pool get up an running again (via zpool import), but the GUI is completly mad. Is there anything I could do to get things back to normal State (in GUI)? My ZFS-Pool is mounted and accessible for the Moment, but I wouldnt be brave enough for a reboot... Maybe anyone can help? I haven't got enough Storage to evacuate and start from scratch again ... Thank you verry much!

May 10, 20233 yr Author Yes, raidz1-1 are the 4 WD RED 10 TB drives. I couldn't add them via GUI. Got a Message regarding different Sizes
May 10, 20233 yr Community Expert Yes, but now you must re-import the pool, though not sure it will work since you added the whole devices instead of partition #1, but it should still work since 2 partitions should have been created, see below how to re-import the pool: https://forums.unraid.net/topic/46802-faq-for-unraid-v6/?do=findComment&comment=1256329 :
May 10, 20233 yr Author I tried it, but got the following Message.... In the second Image you can see the Partionlayout of raidz1-1 disks. There are 2 Partions, as you mentioned Edited May 10, 20233 yr by Thorsten Peters add Image

Not sure a pool with an encrypted vdev and an unencrypted one will work.
May 10, 20233 yr Author Ok you are right, I did it wrong. Followed the Instruction carefully now. But I think you are right, die 4 10TB Disks Dev1, Dev2, Dev3, Dev4 are not encrypted. When I add them, i cannot start the Array anymore. It's complaining about wrong encryption key. So i removed the 4 10TB drives again from pool, did a Reboot and the pool/array is coming back online. Shouldnt it be possible to encrypt the 10TB Drives one by one manually (allways allow the Pool to resilver between actions) ?

This is something I never tried since I don't use encryption, but you'd need to encrypt the devices first then add them to the pool already as encrypted, a resilver won't change that.
May 10, 20233 yr Author Ok, so I'll order another 18TB Disk -> backing up all my Data and set the ZFS-Thing up completely from scratch? Is it possible to add 18 and 10TB drives to the same Pool in the first place? If not, how do i encrypt the drives before adding them?
May 10, 20233 yr Community Expert Solution 6 minutes ago, Thorsten Peters said: Is it possible to add 18 and 10TB drives to the same Pool in the first place? Yes, but due to a known issue you first need create the pool with the 10TB devices, then expand with the 18TB disks, at the moment you cannot expand a pool using smaller devices, though that's perfectly valid.

OK, thank you verry much for your Support! One last question... There is no way to remove raidz1-1 from the ZFS-Pool ?
May 10, 20233 yr Community Expert Nope, you can only remove an existing vdev if the top vdevs are mirrors.
May 10, 20233 yr Author Damn, so I f*cked up in every single way.... Thank you verry much! Have a nice day
