Got an email last night saying my pool was degraded and a hot spare was put into service. Apparently da13 was dropped for unknown reason and I re-seated it this morning. Here is now what the pool looks like
Now with the dropped disk back online FreeNAS is still trying to resilver the pool, is this what it suppose to do?
Here is the SMART of da13, nothing abnormal but I think another burn-in is due when resilvering is complete.
Update: Resliver finished, da13 was directly put back into service, so badblock was not run. Instead a scrub and SMART long test was performed, no errors. Will keep watching but looks like false alarm now.
Code:
root@freenas:~ # zpool status Z2
pool: Z2
state: ONLINE
status: One or more devices is currently being resilvered. The pool will
continue to function, possibly in a degraded state.
action: Wait for the resilver to complete.
