I have been running into some problems with my instance recently. I noticed the parity drive had been disabled, i ran a SMART test and the drive seemed to be in a good state, so I rebuilt the parity using the same drive after verifying the SATA cables were all properly connected (which I assumed to be the problem).

 

This has worked okay for a couple of hours, but just now one of my data disks got disabled after a couple of read/write errors. Since this is the second time within a day, I am somewhat hesitant to just simply re-build the data disk.

 

I already ordered a new set of SATA cables, but maybe there is something more to it that I'm not seeing?

 

I can't run a SMART test at the moment since the device has dropped offline, but I have not shut the system down to check the cables once more.

 

Smartctl open device: /dev/sde failed: No such device

This means the device dropped offline, it's usually a power/connection issue.
