Multiple drives "unmountable" after a restart.

[chrisscott1985]

I replaced several drives due to failure and age. Parity rebuilt. Re-installed some dockers and rebuilt libraries. Performed a restart and now all 5 array drives are "unmountable". Unriad GUI keeps returning me to the Main tab with the drives listed. Parity drives (and data) appear fine. I'm unable to stop the array at this time. Multple restarts (forced and graceful) have not resolved anything. Side note, the lower left corner keeps switching between "Array Started" and "Array Stopped" without any intervention on my part. I have been trying for days to start the array in Maint Mode, but it won't.. Please help!  Thanks in advance!!  Diagnostics attached.

Don't remember seeing this before, it's attempting to mount the disks twice, and the first attempt is successful, update to latest stable, reboot and post new diags.

Fresh update to the latest stable version. Same issue. Took multiple attempts to download diagnostics due to the GUI kicking back to the main screen.

Diags after array start please, and make sure there's only one browser opened to the GUI.

Array started (finally).  But all array drives are "unmountable".  I performed zfs_repair -L on all array drives but 1 (newest drive).

Same thing is still happening, i.e., the disk being mounted twice, suggest redoing the flash drive, backup the current one first and then redo it and just restore the bare minimum, like the key, super.dat and the pools folder for the assignments, also copy the docker user templates folder, if all works you can then reconfigure the server or try restoring a few config files at a time from the backup to see if you can find the culprit.

What will happen to the data on the drives? Should I change flash drives too?

The data should still be there, the disks mount the first time, but then it's trying to mount them again and if fails, because they are already mounted, you can see the data usage on the diags:

 

Filesystem      Size  Used Avail Use% Mounted on
/dev/md1p1      3.7T  392G  3.3T  11% /mnt/disk1
/dev/md2p1      3.7T  340G  3.4T  10% /mnt/disk2
/dev/md3p1      2.8T  2.6T  210G  93% /mnt/disk3
/dev/md4p1      1.9T   14G  1.9T   1% /mnt/disk4
/dev/md5p1      932G   24G  908G   3% /mnt/disk5

I followed your instructions and after a couple of attempts was able to get things running smoothly. Thank you for all your help!  

 

I'm still not sure what was causing the issue, but there are several plugins that I have not reinstalled.
