I had a perfectly ruing system but I had a fan go bad and was making noise so I went to replace it and when I got it back up and running it seemed fine but then later two drives showed up as missing. I went through yesterday and reseated every PCIe device unplugged every cable and made sure to that where replugged tightly at all connections. Turned it back on and everything looked great as I started rebuilding one of the two missing drives. When I went to bed last night it looked great and was rebuilding the drive with ~ 10 hours left. When I checked on it this morning the two parity drives are spun down with errors and one array drive is spun down with errors. The drive being rebuilt was still going and being rebuilt but at ~ 6 MB/s. I am really lost now and I'm not sure what to do or steps to take. I will attach all the system logs, diagnostics, and screenshots. I am going to stop the array.

Thanks in advance for any help,

Chris

Please post the diagnostics

I am sorry about that I thought I did.

Diagnostics come as a zip file, next time, please post that.

Errors on parity2 are not logged as a disk problem, and the disk dropped offline and then reconnected again, suggesting more of a power/connection issue. Check replace cables, especially any power splitters.

I will do that now should I restart and try again? As far as rebuilding?

Starting the array will restart the rebuild for disk2, for disk1 you would need to assign a new disk.

I am going to work on this when I can. My wife's,father fell from a scaffolding a while back and is now a quadriplegic. My wife got a call earlier from the doctor wanting to meet with the family and it's not good. I just wanted to let you know that I am grateful for the help and will work on your suggestion as I can . I didn't want you to think that you provided the help and I blew you off afterwards.

I had a break for a bit and got the power cables inspected and tightened up. I also noticed a switch on my power supply that I think is some kind of Eco Switch that I turned off. I'm confused by why disk 1 & 2 say they are "unmountable: wrong or no file system" and it gives me the option to format the two drives just above where it says "Data Rebuild in Progress". So I hope they are okay and are rebuilding. I am going to add the screenshots of the main page.

Thank you for the help you provided so far.

Disks 1 and 2 are not mounting; cancel the rebuild (unless it's close to completion) and check filesystem on both

It's at 21% running between 100 MB/ sec to 200 MB/ sec. showing 1 day and 2 hours left. Go ahead and stop parity rebuild and do the file system check and repair?

OK I'm sorry but I went ahead and restarted in maintenance mode for xfs but at the bottom where the check button should be there is no button for check. The is only the sync button. The two drives 1 & 2 both now show xfs (see the screenshot). Should I start the sync and if so should I only rebuild one disk at a time?

Again thanks for your help!

You need to click on the disk first to check the check filesystem button.

Okay did that on disc 1. and got:

"Phase 1 - find and verify superblock... bad primary superblock - bad CRC in superblock !!! attempting to find secondary superblock... .found candidate secondary superblock... verified secondary superblock... would write modified primary superblock Primary superblock would have been modified. Cannot proceed further in no_modify mode. Exiting now.

I have the fix button is that Okay to hit?

yep

Thanks. Disk 1 says "File system corruption fixed." Should I run check again to verify? If not I will move on to Drive 2. Assuming that goes the same do I start the array back as normal?

Move on to disk2, assuming it's also fixed, then start the array normally

Okay everything looks good as it is data rebuild is running. Right now it's at 235 MB/ sec and hover at 14 Hours. If nothing happens I will lets you know when it completes and marked as completed. I don't have the extra money until Wednesday but I am setting a reminder to send you something then. As I said thank you. Now I am going to take what I have learned and use it fixing similar issues on a backup Unraid system that I started after this one went down.

Hey have you seen others having the warnings tray go white to where it can't be read?

I sorry that it's off topic.

Yep, it's a known issue with the dark theme for some users.

Thanks. I obviously can make it out it just requires me to admit to be old and putting on some reading glasses.

Back on topic my servers data rebuild is at 80 % and 5 hours. Everything is looking good.
