And that disk (ada2) became unavailable. gpart show does not even list the disk or it's partitions. I am guessing zpool labelclear -f /dev/ada2 destroyed the partition table. Answer to Ricky's question: No I used geom names (ada2p3). I cannot figure out the reason for the GUID mismatch (see console image). Any ideas?
