In a perfect world dump would be able to figure out if there's enough space to make the snapshot before attempting it. At the time I was just using it to migrate to a new larger hd on my new laptop and was single user, though I had all filesystems mounted rw. That last bit was probably just laziness on my part. Anyways I read the manpage, tried -L, and it ran out of space and hung my system. Seemed very ugly at the time. Seems to me in many situations when one is using dump/restore one expects (or hopes) that they'll be as robust as possible. I hope that's enough of a report for dump's maintainer to take a quick try at reproducing the problem. I don't have any free cycles and won't have until the Fall :( - --Andrew -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.4 (FreeBSD) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFHg91c8It2CaCdeMwRAkKrAKCBWl6z3SfWPPlqUuvCk2skrLvfVwCfSUtp K3bFIvLc0q0A3ziJLJ0ycFQ= =vG6U -----END PGP SIGNATURE-----
