I have not much time lately to >> look at this problem, but would like to get additional data points. As the submitter of 100365, I still don't think that snapshots on amd64 are working correctly. When I (still) run the code attached to the PR, I still see a problem -- the problem is that sometimes the filesystem is busy and mksnap_ffs "errors out" and doesn't create a snapshot. I spent a little bit of time looking at mksnap_ffs to see if I could get it to retry the snapshot if the filesystem is busy to no avail. I've given up on my automated script to do a backup and just generate (and fsck by hand) a snapshot until I get a working one.... Thanks, -SR -- Stephen J. Roznowski (sjr@comcast.net)
