Hi,

 

So I just got my first ever hard drive failure. I got an alert saying one of my drives had errors. Took a look at the array and saw one drive was emulated. I checked the logs and found this:

Jan 26 19:27:37 MELCHIOR kernel: md: disk2 read error, sector=10903897736
Jan 26 19:27:38 MELCHIOR kernel: md: disk2 write error, sector=10903897736

 

This is what the Disk Logs says:

Dec 28 13:36:30 MELCHIOR kernel: mdcmd (3): import 2 sde 64 11718885324 0 WDC_WD120EMFZ-11A6JA0_9RJ64SWL
Dec 28 13:36:30 MELCHIOR kernel: md: import disk2: (sde) WDC_WD120EMFZ-11A6JA0_9RJ64SWL size: 11718885324
Dec 28 13:36:30 MELCHIOR emhttpd: read SMART /dev/sde
Jan 26 19:09:51 MELCHIOR kernel: sd 8:0:0:0: [sde] Synchronizing SCSI cache
Jan 26 19:09:51 MELCHIOR kernel: sd 8:0:0:0: [sde] Synchronize Cache(10) failed: Result: hostbyte=0x01 driverbyte=0x00

 

I can't seem to be able to start a SMART self test.

Its a chucked WD 12TB, running about 1,5 years. I'm rocking version 6.9.2 with 2 parity drives. The drive itself is pretty full, 94%. I've got a spare 12TB lying around. Should I start preclearing it an replace the failed drive? Or can i check something else first?

 

regards,

attach diagnostics to your NEXT post in this thread.

So, turns out my kid opened the hotswap bay whilst playing. I popped it back in, but unraid couldn't find the disk. I was able to add it as a "new" one. I'ts currently rebuilding onto the same old disk. This can't be right no?

Once a disk is disabled (which it would be if removed with Unraid running) it has to be rebuilt to get it back into use.

Not quite sure what you then did - did you follow the procedure documented here?

Yeah, kind of.

Ok, then everything checks out as it should be, nothing to worry about (except finding a new spot for my server, my little toddler is fascinated by flashing lights).

I expected to just pop it back in and continue with my day. Thanks for the quick help and info!
