Disk Failure Detected...
I've recently purchased a ReadyNAS Ultra 6 along with 6 2 Tb Seagate ST2000DL003 disks (which are on the HCL). I've set up the NAS in a dual redundancy X-RAID2 configuration and have starting copyi...
Everything has been running fine since the 16th March... until today -- this time disk 5 was reported as failed.
Just like you, the health status was listed as 'dead' (not failed) with 'SMART+' greyed out. I have exactly the same disks ( ST2000DL003-9VT166) and exactly the same firmware (CC32).
I powered down the NAS, pulled the disk out, switched it back on and reinserted the same disk and the disk came back to life and started to resync. It's interesting that you found that even a hot swap of a new drive didn't work... which would (presumably) suggest a problem with the disk interface on the NAS rather than the disks?
Surely I can't have 3 failed disks out of 6? Once the volume has resynced, I'll do another extended disk test, but the first one came back fine after disks 2 and 4 had failed.
What's the official advice here? I can't really send back 3 disks which to all appearances work perfectly well and have no errors (and pass the extended test)... but I don't want to risk having multiple disks 'fail' in this manner and loosing my data. Is there some kind of incompatibility between the CC32 formware and the NAS? What version of the disk / firmware was tested when the disk was put onto the HCL?
Thanks,
Ash.
