Identify a Failing Disk
Disk Smart test errors are reported by device ID (e.g. /dev/sdw), rather than the serial number. To find the serial number associated with a particular device ID, run the following one-liner with $dev substituted for the device to find:
TODO
Get Serial Number from part-uuid
ls -l /dev/disk/by-partuuid
Will return lines for each partition device and its mapping to a /dev/sd Linux block device.
From there, run smartctl -a <block device> | grep Serial where <block device> is like /dev/sdw.
Or, as a one-liner with $DISK_UUID set to the UUID to find:
ls -l /dev/disk/by-partuuid | grep $DISK_UUID | cut -d' ' -f 11 | xargs basename | sed 's/^/\/dev\//' | xargs sudo smartctl -a | grep Serial | tr -s ' ' | cut -d' ' -f 3
It might be possible to pull the part UUID from the zpool status command directly. An exercise for the reader.
Offline and wipe the failing disk
- Match the disk name (e.g.
/dev/sdw) to the UUID (e.g.13846695584571018356). Uselsblk --fsfor this. - Offline the disk:
zpool offline $pool $disk_id - Wipe the disk:
wipefs $disklabel(where$disklabelis like/dev/sdw) - Run
lsblk --fsagain to verify the wipe worked. If not, you'll need to run a full dd wipe withdd if=/dev/zero of=$disklabel bs=1M. This will take a long time as it writes zeroes across the entire drive. - Physically remove the disk.
Replace Disk in Pool
Once the failed disk has been identified and physically replaced, you should know the old drive's UUID (via zpool status) and the new drive's device name (via lsblk and deduction)
Once the new drive is in place and you know its ID (e.g. /dev/sdw), run the following to begin the resilver process:
zpool replace <pool> <part-uuid to be replace> <device id of new drive>
E.g. zpool replace Media d50abb30-81fd-49c6-b22e-43fcee2022fe /dev/sdx
This will begin a new resilver operation. Good luck!
