Parity Disk showed as New

Recommended Posts

I'm running identical hardware to the 20 drive Tower from Raj. I haven't added the controller cards yet so I have all 6 drives connected to the motherboard.

The drives are Seagate Barracuda Greens 2TB, all were successfully precleared before being added to the array.

I rebooted the server after I got the error and the syslog reset and only has entries since after the reboot so I don't think that will be much help.

It is rebuilding the parity on the same original parity disk right now.

I just wonder if moving and deleting folders from one share to another as well as reassigning the disks to the shares might have screwed things up.

Actually it looks like I may have a problem with the parity disk.

Now I get this error when trying to run the short smart test from unmenu

 

smartctl -t short -d ata /dev/sda 2>&1

smartctl 5.39.1 2010-01-28 r3054 [i486-slackware-linux-gnu] (local build)

Smartctl: Device Read Identity Failed (not an ATA/ATAPI device)

 

A mandatory SMART command failed: exiting. To continue, add one or more '-T permissive' options.

 

 

HELP!

I am back where I started, Parity disk showing as new and rebuilding again.

Appears to be having issues with disk 4 as well.

Could this be part of the problem?

Nope that is normal.  Check all the power and data cable connections. Your drives are either dying or you have a power connection problem.
