Hello all
I have a home freenas backup/plex box that I first set up in Aug 2015 and has been pretty much running without issues so far. I am running the OS on two mirrored USB drives.
A few days back I noticed an email from the box which said that one of the boot drives had some unrecoverable errors.
I ran
and see the following output
[root@bazinga ~]# zpool status -x
pool: freenas-boot
state: ONLINE
status: One or more devices has experienced an unrecoverable error. An
attempt was made to correct the error. Applications are unaffected.
action: Determine if the device needs to be replaced, and clear the errors
using 'zpool clear' or replace the device with 'zpool replace'.

errors: No known data errors
the second USB boot drive seems to show 17 checksum errors and the status remains online. Has been this way for a few days now and has not degraded or increased the count of checksum errors.
So Part 1 of my question is do i need to replace/resilver the usb boot drive with the errors?
Part 2 is how should I identify which of the two mirrored usb boot drives has the problem.
