Hello, Everyone!

 

I have 2 Unraid servers. At some point both of them started to disable disks due to errors. My guess that it was somehow connected with the update to Unraid 7.0 (but may be it is just a coincidence).

 

On one server the problem was solved by replacing all of SATA cables to a new ones and updating to Unraid 7.0.1 (again - may be it is just a coincidence).

 

On another server the problem persists. Please refer to the attached screenshot. 

 

The drive marked as 1 is connected via cable, the drive marked as 2 is connected directly to the motherboard (SATA connection the same as in notebooks).

 

At first problems started with drive 1 - the system started parity check, showed some errors and disabled the drive after that.

That hard disk was old, so I simply bought a new one. It worked for some time (1 or 2 weeks) and at some point errors started to show up again (and on the second drive too). I had 2 new spear SSDs, so I've changed both HDDs to totally new SSDs (it was in the beginning of January).  Again they worked for a week or 2, and errors started popping up on the drive 1.

At this point I realized that the problem could be in the cable - so I changed it to a new one. And updated Unraid to 7.0.1. After that the was no errors with drive 1 for a month, but errors started happening with drive 2. Again: drive 2 is connected directly to the motherboad, I cant change a cable there.

 

The attached screenshot is made today: we see errors on both drives. I don't know what to do and I have a feeling that this is a software issue. 

 

Attached: server diagnostics, logs from SSD in drive 2, a screenshot and 2 photos of troublesome server.

 

Please advise.

Looks more like a power/connection issue, replace both cables and try again.

I've changed all cables, changed ports on motherboards. Same problem.

 

Both servers have disabled disks. Please advise.

 

Also, how to enable disabled disks?

GLUK server is still showing constant ATA errors on parity, if you have already replaced both cables, you should try with a different disk, SMART for it also looks kind of strange, very few attributes.

 

Alraminar still looks like a power/connection issue, but again, if you have already replaced both cables try a different SSD.
