Help needed in upgrading to 12r5 with existing ZFS pools via ZFS-Plugin by steini84

[OneMeanRabbit]

I tried it initially following the paragraph from the RC1 & RC3 blog posts.  

 

Quote

Pools created with the steini84 plugin can be imported as follows: First create a new pool with the number of slots corresponding to the number of devices in the pool to be imported. 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).

 

That didn't work initially, because I seem to have some ghost user shares in a config file (not showing in UI Shares) with the same names as my zfs pools - nvme & hdd.   I created new pools as above, and had to choose new names.  After adding the new pools of 8 drives (2 raidz1 vdevs) & 1 nvme (raidz0), it changed my pool names.  It couldn't find any data and it had the "Unmountable: Unsupported or no file system" error.  I kinda freaked, and rolled back to 11.  Still couldn't find my data, and then tried

 

zpool import -a

and it worked.  To fix my existing shares/docker mappings, I

zpool export <new pool names> 
zpool import <new pool names> <original pool names>
  

 

Fine, back to "normal" except system was acting funny...ZFS pools wouldn't auto import at boot and weird docker behavior.  Today I tried again, and just simply zpool import <original pool names>, and while it worked initially - I can't get them properly into a new pool.  Still shows "Unmountable: Unsupported or no file system" even though everything else works fine.

 

Questions:

1. Any value to using my zfs pools as unRAID pools vs just keeping them "segregated"?
   1. If there is value, is there anything in my configuration that precludes importing them in as is in the current release?  
   2. How should I set them up with "cache" settings when I don't really require that type of backend mgmt?  System runs fabulously as is, with 2 flash drives as my "fake array", and 2 SSDs as my only pool to host my "appdata" - mainly docker folders, as i was having some crazy pain around how ZFS was creating infinite snapshots of their images.

Please post the diagnostics after a pool import attempt using the GUI.

Forgot to attach this on original, thank you and sorry for having to waste time requesting! 

 

Started looking, I can see mention of my nvme.cfg under shares, but want to remove it completely so I can eventually reuse it when figure this out.  That would be a quick win for me, thank you!

To clarify, I'm on RC5 now - but before starting array, I

zpool import -a

which brought in my hdd & nvme pools.  The status are good and shares NFS/SMB work great.

 

Then I created a pool in the UI called "hdd" which it let me, and I added the 8 drives with raidz & 2 groups of 4 devices.  The pool shows up, but still has the "Unmountable:" error.   However, everything seems to work fine, except that I had to increase permissions for some reason on my appdata/docker folder for a few containers - adminer & nextcloud.

Did you export the pool before attempting to import using the GUI? It can't import a pool that is already online.

[JorgeB]

Yeah, looks like that was the problem, or at least a problem:

 

May 10 12:22:55 tower emhttpd: /usr/sbin/zpool import -d /dev/sde1 2>&1
May 10 12:22:55 tower emhttpd: no pools available to import

Prior to upgrade and reboot, I did export my pools. 

 

After upgrade and reboot and before array start, zpool status = no pools exist.  Now that I'm where I'm at, what should I attempt, if I want to include it in my unRAID pools.  Would love your thoughts on my questions, or any other people's.  Thank you kindly for taking your time helping!

Reboot to clear the logs, don't import the pool manually, try importing the pool with Unraid, post new diags.
