One drive initially marked as failed, Resync now at 6.3% after 12 hours. What next? ReadyNAS Ultra 4
Decided to do some housekeeping and was deleting files from the Ultra 4 when I checked Frontview and found that one of the drives had been marked as having failed. I immediately shut down the NAS ...
What stats are you seeing on disk 4 - particularly pending sectors, reallocated sectors, and ATA timeouts?
Are stats getting worse for any drive while the resync is proceeding?
Thank you for your quick response!
Here are the stats from Drive 4 (very similar to the others)
SMART Attribute Spin Up Time 0 Start Stop Count 3453 Reallocated Sector Count 0 Power On Hours 45055 Spin Retry Count 0 Power Cycle Count 315 Runtime Bad Block 0 End-to-End Error 0 Reported Uncorrect 0 Command Timeout 3 High Fly Writes 0 Airflow Temperature Cel 31 G-Sense Error Rate 0 Power-Off Retract Count 11 Load Cycle Count 3454 Temperature Celsius 31 Current Pending Sector 0 Offline Uncorrectable 0 UDMA CRC Error Count 0 Head Flying Hours 64265595669968 Total LBAs Written 412058933 Total LBAs Read 3157320595 ATA Error Count 0 No real changes that I see occuring for any of the disks.
Thanks again.
The only possible concern in the stats would be the command timeouts - and if they aren't increasing they aren't happening now.
Completion estimates for resync on the ultra/pro are often way off, but it should be farther along than 6% by now.
I think I'd let it complete if you can stand the poor performance.
You could of course pull drive 4, and the resync would stop. But I'd be more inclined to do that if we were seeing clear evidence that the drive was getting worse - and we aren't.
Ok. I will keep an eye on the SMARt status for the drives and check it again in a few hours. Hopefully the Resync speeds up a bit.
Thanks again for your advice!
