(SOLVED) Parity Check Sync Errors Corrected Sharp Increase

[snuffy47]

Hello

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

 

Thanks

Do that and post new diags if there are more sync errors.

Howdy

 

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

Just shut server down second time and checked all cables and also replaced Disk 7 Sata cable

 

Booted back up and UNRAID returned to normal.  Parity check start over on its own

 

Diag log attached

 

Anythoughts on what is happening would be appreciated.

 

Not touching the damn thing for few hours lol

Server restarting by itself during a check suggests a hardware problem, you can try enabling the syslog server, it might catch something.

[snuffy47]

syslog server setup in server to report back to itself though I need to figure out how to save it to an unassigned devices usb drive incase server doesnt boot

 

so far knock on wood 3rd parity check is going good with no syncerrors and should be done in few hours

 

thanks for help

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

 

 

[snuffy47]

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)

Going to mark as solved and really appreciate all the help
