[SOLVED] Error creating datastore on NFS mount

Solved! I hope it can help someone else.

So this is my infrstructure and what happened:

PBS 2.2_1 mounting datastores with Nfs protocol
Nas Qnap QutsHero sharing folders with Nfs protocol
Power interruption caused by a blackout
After the reboot the PBS can't mount the Nfs datastores so I had to interrupt the Nfs sharing service on the nas side after few seconds reactivate it and reboot the PBS. Now the shared Datastores was mounted but not accessible/with content unreadable and gives a 'permission denied' error and 'os error 2' during the backup process but I could see the remaining capacity on Datastores.
After a long investigation between the permissions and folder owners (I also gave permissions to read/write to the root and admin group on every shared folders but this NOT solved the problem).
Searching somethging wrong in the Syslog in PBS i found this issue with a missing file *.blob in a snaphot folder (I got more than 100 snapshot folders).
Looking for this specific one i found it empty and it was dated to the day after the blackout, so i looked for all the folders with this date and the blackout date between my snaphots folders on the nas and deleted all of them. After that everithing seems to work perfectly fine.

Also thanks to Chris for his time and support
