Running 6.8.3,

Disk 1 had an UNMOUNTABLE: No files system problem last week which had to be repaired

Swapped out MOBO and CPU with Supermicro X8DT6-F late last week

Started a parity check April 11th around 17:00 EST which completed today.

This check indicated 19171 errors (Correct errors selected)- have attached the parity check histoy and system log

Also attached diagnostics file


Looking for some insight on what might be happening to my system.


Thinking will run another check tonight

Well I am not having any luck in last few weeks


Second Parity check was about 75% complete with no errors but the server restarted in that last few minutes and booted back up in mess


When it booted it said array not started too many disks.


I shut server down and started again it now states stale config and is missing Disk 7 grrr


Thought things were going good on parity side but guess not


Diagnostic file attached

Well all has been quiet


parity check was completed with no errors.  I did have a lock up after a requested reboot and then my wife pulled my ups cord out but everything seems to be work okay


Have attached diagnostic file for what it is worth


Will also need to look at UPS settings as it caused an unclean shutdown :(


Have syslog server running and backed up my critical files but have no idea what happened :( and if it will return


Really appreciate the help and let me know if there is anyother loging or testing I can do

Only issue I see is a USB device (mounted as /mnt/disks/USB_TOURO) disconnecting without being unmounted first, generating a lot of errors:

Appreciate looking at this


That was done on a reboot and the server was hanging on the os selection screen.  Had to unclean restart then.


Knock on wood everything ran great over night and running 3rd parity check and syslog server is running


Kinda worried but have my critical unreplaceable files backed up now and will continue to do so


On a different note disk 1 was giving out errors with old mobo config but with new setup not 1 hdd error over 2 parity checks.


Guess in monitor mode

Well not sure what the deal is but last 24hours everything is operating perfect.


Maybe calm before the storm but really not sure can do anything else but watch


3rd Parity completed this am with no errors and none of my disks recorded any new errors either


Event: Unraid Parity check
Subject: Notice [TOWER] - Parity check finished (0 errors)
Description: Duration: 22 hours, 14 minutes, 4 seconds. Average speed: 100.0 MB/s
Importance: normal


Going to mark as solved and really appreciate all the help
