I have two hard disks in my drawer which still contain data. I haven't used them for some years now. Initially they were running in a RAID-1 setup using gmirror. Before I put them in the drawer I used one of those disks individually for some time (i.e. without having the second one running in the gmirror, or lets say I was using the gmirror intentionally as DEGRADED).
Question(s): How can I find out which disk contains the most recent data (without looking at the data itself)? Is there anything within the gmirror metadata to distinguish? How will gmirror act in case I attach both disks to a system again? The manpage writes something about a priority value which depends on the order the disks were labeled during initialization.
