The /dev/fss? devices will not allow multiple opens. To dump a snapshot
please use the -x / -X flags. In your example it would be:
dump -L maat-home -b 32 -0eautf /dev/nrst0 -x /var/tmp/maat-home /home
This appears to work properly, however I have no indication that a snapshot was made or even used aside from this:
[16:42:52 EDT] DUMP: Dumping a snapshot of /dev/rld0g (/home) to /dev/nrst0
Is it safe to assume that I don't have to create the snapshot with fssconfig first? And that dump takes care of that for us? It's not really clear in dump(8).
Another thing - fss in general (both via dump and by itself) is considered "experimental" but I haven't had much trouble with this until now. Is this because there has been limited testing? Limited resources to maintain/develop it? Perhaps it's not as stable on ports other than i386.
I consider this a very important feature and would like to see it considered "stable". It would also be good to get rid of some ironic (albeit funny) documentation in the manual, such as:
-x snap-backup
Use a snapshot with snap-backup as backup for this dump. See
fss(4) for more details. Snapshot support is experimental. Be
sure you have a backup before you use it.
... from the dump(8) page.
Thanks for your help. Any further clarifications would be most appreciated.
Louis
