[SOLVED] 198 Offline_Uncorrectable 0x0030 ...

[soana]

Can somebody explain to me what the error below means? It happens on my parity drive

198 Offline_Uncorrectable  0x0030  200  200  000    Old_age  Offline      -      1

I did search the net but can not find anything to explain what Offline_Uncorrectable means.

 

Also while running parity check I get the following:

Apr 15 10:43:45 Tower kernel: handle_stripe read error: 428512/0, count: 1 (Errors)

What does handle_stripe error mean and should I worry about it? Forgot to mention the above error is on disk_0.

 

Like I said before I did my best to search the net for these two items and could not find an answer, but then I'm new at this RAID stuff and might not know where to look for the answer.

Post a syslog. See here for SMART info: http://en.wikipedia.org/wiki/Self-Monitoring,_Analysis,_and_Reporting_Technology#Known_ATA_S.M.A.R.T._attributes

Thanks for the link.

Should I worry about the drive with the 198 error? Does it need to be replaced? I think I did run preclear for this drive.

The smart history shows this: WD-WMAVU0356959: WARNING - Offline_Uncorrectable it is now 1 (warning threshold is 1)

Attached is the syslog.

The parity drive has some unreadable sectors. Post a SMART report for the parity disk.

Smart report attached.

The drive looks ok. Rebuild parity: Start the array with parity unassigned. Then reassign the parity drive and start the array. Parity will rebuild.

Many thanks dgaschk!
