Hi all, just to wrap this issue up: as FMA didn't report any other error than the one which led to the degradation of the one mirror, I detached the original drive from the zpool which flagged the mirror vdev as ONLINE (although there was still a cksum error count of 23 on the spare drive).

Hi, today I issued a scrub on one of my zpools and after some time I noticed that one of the vdevs became degraded due to some drive having cksum errors. The spare kicked in and the drive got resilvered, but why does the spare drive now also show almost the same number of cksum errors, as the
