May 12, 201313 yr had a disk come up last night disabled, thinking it could just be a loose cable i shutdown, checked cables and started again. There is currently one write error although last night there were several. the drive is mounted as SDE and passes smart tests without errors. I have attached my syslog. Simple features says no errors are logged on the disk My version is 5-rc12a syslog-2013-05-13.txt.zip
May 12, 201313 yr Author Is it now shown as okay on the Web GUI? Check the SMART status and post it here. It was still shown as disabled after restart but smart said a short test completed with no errors, will have to wait till I get home from work to post smart status
May 12, 201313 yr Is it now shown as okay on the Web GUI? Check the SMART status and post it here. It was still shown as disabled after restart but smart said a short test completed with no errors, will have to wait till I get home from work to post smart status Once disabled a disk will NEVER go back to non-disabled by itself. A write to it failed. It is is why it was disabled. The contents are guaranteed to be incorrect. (because the write to it failed) It MUST be re-constructed, or forced back in if you can deal with the file or file-system corruption. That re-construction has absolutely nothing to do with a failed or passed short or long test. The fact that the disk is responding means it is not completely dead. You might have fixed it when you re-seated the cables. to re-construct the drive, stop the array, temporarily un-assign the failed drive. then start the array with it un-assigned. (unRAID will then forget the model/serial number of the drive and allow it to be used as its own replacement.) Then, stop the array once more, and re-assign the drive, then re-start the array. the failed disk will be re-constructed from parity in combination with all the other drives.
May 12, 201313 yr Interesting trick to force a re-build with the same drive. I've done this exact thing before when a drive wasn't seated well in a hot-swap cage; but I didn't remember removing/replacing it in the array. [it's been a couple years, so my ageing memory apparently just forgot ] In any event, that drive is still working perfectly 2 years later -- so if your problem was indeed just a cable that needed to be reset, you should be fine once the system rebuilds it.
May 13, 201313 yr Author So Is the drive salvageable if I rebuild it? It looks as though it is (to me) but I'll upgrade ut to 3TB if its gonna die Last SMART test result: Completed without errors SMART status: Passed Device Model: ST2000DL003 Serial Number: 5YD59HH6 Firmware Version: CC32 User Capacity: 2,000,398,934,016 bytes Device is: Not in smartctl database [for details use: -P showall] ATA Version is: 8 ATA Standard is: ATA-8-ACS revision 4 Local Time is: Mon May 13 15:25:58 2013 EST SMART support is: Available - device has SMART capability.

May 13, 201313 yr It certainly seems like it is. Do as Joe noted and see if it rebuilds okay. If not, simply replace it with a nice new 3TB drive
May 13, 201313 yr This parameter in the SMART report indicates the drive retracted its heads on unexpectedly losing power over 400 times. 192 Power-Off_Retract_Count 0x0032 100 100 000 Old_age Always - 402 That points to a power supply/power cable/power connection issue.

Good catch Joe - I missed that (it's on the left side in my browser .. I needed to make the window wider!) It's actually amazing how often apparently failing/failed disks can actually be a cable or power issue.
May 13, 201313 yr the psu is only about 1yr oldAge has nothing to do with whether or not it is the issue. Brand new parts can fail.
May 13, 201313 yr Author Yeah, I guess I will have to just wait and see if anything else occurs? I just remembered that this disk was green until I started using Midnight Commander to re-balance my disk usage after installing a new 3TB drive
