Carbon copy cloner, which had been doing a clone of the xsan volume nightly started to complain that there were multiple dries with the same unique identifier as the source. After looking I find that diskutil list shows multiple instances of the volume. I've restarted the backup system and unmounted and mounted the xsan volume but only went from two phantoms to 3. I haven't been able to shutdown the entire fabric yet because I haven't been able to schedule downtime for the server.
Anyone seen this before? Any tricks to resolving this?
Here is a portion of the diskutil output:
/dev/disk3
#: TYPE NAME SIZE IDENTIFIER
0: Apple_Xsan_Component *2.0 TB disk3
/dev/disk4
#: TYPE NAME SIZE IDENTIFIER
0: Apple_Xsan_Component *18.0 TB disk4
/dev/disk5
#: TYPE NAME SIZE IDENTIFIER
0: Apple_Xsan_Component *18.0 TB disk5
/dev/disk6
#: TYPE NAME SIZE IDENTIFIER
0: Apple_Xsan MyVolume *36.0 TB disk6
/dev/disk7
#: TYPE NAME SIZE IDENTIFIER
0: Apple_Xsan MyVolume *36.0 TB disk7
/dev/disk8
#: TYPE NAME SIZE IDENTIFIER
0: Apple_Xsan MyVolume *36.0 TB disk8
