I ran into a host of issues after applying the 6.2.2 upgrade, including two unmountable disk issues.  Don't believe it was just a coincidence. 

 

First, after rebooting from the upgrade was my 2TB drive unraid indicated failed, though Smart status and log said it was good.  Attempting to recover it, and have the parity drive rebuild it.  Seemed to work.  After this found an issue with a Mythbuntu VM which I end up scrapping completely, as it was in really really pour status, no X11 interface, multiple xml files corrupt, nothing worked.

 

After a restart of Unraid the same 2TB drive stated it was unmountable along with another 3TB drive.  Going into maintenance mode was able to do a "check -n" and the 2TB drive was able to come back online  ?!?!?!?!?  The -n should have done nothing.

 

Was able to get the 3TB drive online after doing maintenance mode "check -L" 

 

Now I've got at least one share that shows no data yet the disk themselves /mnt/disk1, 2, 3/.....  show the files being present.  Just the share is shows empty.  Not sure how to correct that.

Splitting this. Don't hijack.

I ran into the exact same issue as the OP in the unmountable disk issue faulty disk declared, with SMART stating the drive was good.  But that's neither here or there I guess.  Thanks for the support assistance into /dev/null.

Even if it was the "exact" same (no evidence), it is usually best to keep different users support separate to keep the thread focused. If you are asking for support, post your diagnostics.
