why the geom name isnot same with gpart show name with same disk ?
how to modify gpart show name to be geom name ?
i just want to use the short name nda0 in gpart command, not diskid/DISK-82VC71X3E6CK .

any one can help me ? thanks.
 
Output of following:
sysctl -a | grep -i label | grep -i geom
ls -l /dev/nda0

In general this is probably "GEOM withering"; something has mounted the device using /dev/diskid/DISK-82VC71X3E6CK which makes the node /dev/nda0 disappear.

That will do it. That implies when the zpool was created the command used the diskid label.
As root if you do "zpool history" you get all the commands ever done to pool; first one should be how it was created.

Now what T-Daemon shows is how you would turn off the diskid labeling; I don't know if that would affect how the zpool gets mounted. If nda0 has your zroot on it, I would be careful about blindly turning off the disk labels.
I've moved things around but my devices were mirrored so it was trivial to detach one device, then reattach using a gpt label, wait for resilver, then repeat with the other device.

A zpool with a single device? Maybe booting into a live image one could do it.
