smartd error [ATA error count increased]

I got a mail to root, (same error in syslog)

The following warning/error was logged by the smartd daemon:

Device: /dev/bus/0 [megaraid_disk_12] [SAT], ATA error count increased from 0 to 9

Device info: ST13000NM0005-2A1201, S/N:ZVJ2GZSP, WWN:5-000c50-0b3bg13c3, FW:SN02, 12.0 TB

After running two tests on it,

$ smartctl -l selftest /dev/bus/0 -d megaraid,12

/dev/bus/0 [megaraid_disk_12] [SAT]: Device open changed type from 'megaraid,12' to 'sat+megaraid,12'

Can you please help in understanding and getting the failed disk if any. Thanks


Yes, this 10 Tb disk, with serial no. ZVJ2GZSP, is dying. I wonder why initial report said it is 16 Tb.

It already used over 9000 sectors in reserved area:

5 Reallocated_Sector_Ct   0x0033   098   098   010    Pre-fail  Always       -       9208

I think you can remove it safely, because all storage on this RAID controller is redundant (RAID1 or RAID 10) and all is Optimal. You have to set this disk to Offline. Once disk is set offline one of GHS (global hot spares) should get up and replace this disk in its array.

This disk is in the enclosure bay no. 9 (remember, these are 0-based, so it is 10th one). However, to be certain, you might use locate function of your enclosure.

For details see controller manual.
