I usually shutdown my Unraid box every 2 weeks or so but always make sure it is on for 1st of month (monthly parity checks). I hit power button and after normal 30 seconds to 1 min to shutdown, it didn't shutdown. I confirmed by walking away and after 5 minutes it was "still on". It is a closed system (no outside internet and just UNRAID, KODI box, and TV) so I look at it once a month just to check that monthly parity is ok. By the way last year of parity checks have all come back with ZERO errors. I forget how I got it to "turn off" but after reading the "need help, read me first" post I realized I may have lost vital info for you to assist since it said "once you reboot, syslog is lost". 

 

So finally opened up webGUI a few days later (it was off for a few days since I was busy and couldn't work on it) to find red X on parity drive! I read through rest of readme post and have diagnostics file attached for help. Other than turning Unraid box on to see webGUI red X on parity drive and getting diagnostics I haven't touched anything or clicked any buttons until I hear what to do from this forum. 

 

With red X on parity I assume I am going shopping for replacement parity drive?

 

I am total noob and will await further instructions before I go to next step. 

Thank you

Disk looks fine, without the pre-reboot logs more difficult to say but probably a connection issue, suggest replacing the cables to rule them out and re-sync parity:

Wow, didn't expect reply THAT fast. So reading that post we think drive is fine and using "option 2" (rebuild drive onto itself) won't delete any data?

 

Is this process short or long. Meaning ~5 min or more like multiple hours (similar to preclear)? Just so I know and don't do something stupid because I "think it isn't working" but in reality it is doing fine.

 

Question. Is this similar to how I would REPLACE a parity drive? and in short that is what we are doing by unassigning parity, start array, stop array, re-assign parity disk, start array, let it rebuild itself?

 

HERE ARE STEPS TO REBUILD DRIVE ONTO ITSELF (option #2)

--You can re-enable the hard drive and reconstruct it as follows:

--Stop the array.

--Go to the Main page (Devices in version 4.7) and unassign the disk.

--Go to the Main page (Array Operations section) and start the array.

--Stop the array again.

--Go to the Main page (Devices in version 4.7) and re-assign the disk.

--Go to the Main page (Array Operations section) - the system should indicate there is a "new" drive to replace the disabled one. Check the confirmation box and click the Start button to start a reconstruct/rebuild of the disk.

 

Thank you for help

Parity doesn't contain any of your files.

 

The entire parity disk will be rewritten so it will take several hours.

 

Ok, glad I asked and thank you for clarification.
