Y'know, I didn't get any error message that the mirror failed, but the df showed the volume at 103% and the used space wasn't equal to the source volume, so I assumed that the mirror had failed due to lack of space. Now you are saying that it might have been only cosmetic - that just the df information was wrong, but the data was copied in full. Maybe, but how am I to know? We are at 5.3.6R2 by the way.

I would agree with the previous mail. Snap list on the destination volume will show the snapshots that have made it to the destination. The snapshot name has a numeric suffix. That number is bumped up each update. So take a look at the snap list on the source and the dates on those snapshots. The snap list on the destination should have the same snapshots and the date on the newest snapshot is the last time they were updated.
