Hi, since I am new to Unraid I jumped straight into running ZFS that I setup ona late rc build and now 6.12

 

So I have set up a small zpool with 4 drivers as well as a standalone zfs drive for "disk1" and a single cache drive, created shares and exported with SMB, and I also installed docker and it all worked.

 

But today something odd happened and now in the web GUI on the "Main" page all my ZFS disks show as "Unmountable: Unsupported or no file system" and it wants me to format all the drivers.

However, all the zfs pool are infact online and I can access all the data, I can stopp and start the "array" and it goes back to this state.

 

 

 

I can scrub the pools and it also fine, and yes, there is no problems accesing to docker contains or the SMB shares.

 

Exempel status:

          md1p1     ONLINE       0     0     0

In the log file from when starting the array I get lines like these :

 

Jun 16 19:19:17 gen8 emhttpd: mounting /mnt/mainpool

Jun 16 19:19:18 gen8 emhttpd: shcmd (144136): /usr/sbin/zfs mount -a

 

And if I check with lsblk I can see that the "cannot import 'diskuuid' actually match with already mounted diskuuid's  because yes they are  already mounted and working:

So it seams like the zfs pools, samba, docker etc all works but the  "array" and GUI status is out of sync ?

Any ideals on how to resync it so to say ?

 

That suggests the pools were already online before array start, you need to export them, then start array, Unraid need to do the importing, if it's not that please post the diagnostics.

Wow, that successfully resolved the issue!

 

Performing a stop of the "array", then an export of my three pools and restarting the "array" again. 

Everything is back to normal now. 

 

I appreciate your speedy assistance very much!
