Disk in error state (disk disbl), disc write errors on rebuild.

Featured Replies

I am having issues after restarting my server. Everything was working fine yesterday, but after starting up today I am having issues with one of the discs. I had the system off this morning to try and adjust something inside my PC case that was rattling. I did not unhook any cables or anything. After turning it back on and starting the array one of my discs went into an error state. I did short self test with no errors. I tried to stop the array, remove disc, restart, stop, add disc, restart, rebuild but got a write error when trying to rebuild the array. I then turned off the system to check all the cables even though I hadn't touched anything. All cable connections seem fine. Tried the process again with same results. Short self test again had no issues. Not sure what to try from here except the extended smart test.

 

I have uploaded the log files.

 

Please let me know what to try from here.

Swap both cables with a different disk and try again.

I won't be able to swap cables until later today. If I swap them with another disk and the cables are bad, won't that cause the other disk to enter an error state and then I will be down two discs that need to rebuilt? I imagine you're suggesting to swap them so that we know it's a cable that already works rather than a new untested cable. I do have double parity but it makes me nervous not having any backups left if I have to rebuild two drives.  I'm currently using a SAS breakout cable and I tried one of the extra SATA connections that wasn't being used and had the same issue. I will try a brand new SATA cable when I am home. I may be able to steal a power cable from my fans for testing too. If all that fails I will try swapping with an existing drive.

 

I didn't think it would be a faulty cable since I am always very careful when I open my case, but the extended SMART passed without error so not sure what else it could be.

You can also use new cables if you prefer.

Rebuild has been going for about a day without errors so I am guessing the new cable fixed it. Guess I need to be wary of amazon cables.
