[9fans] snapshots

[Christopher Nielsen]

I ran a snap -a on my fileserver before leaving on a
trip, hoping it would be done when I returned. Now
that I have returned, I do not see a fingerprint in
the logs, nor are the disks still spinning. That makes
me think that it didn't complete. Also, I cannot
connect to the fileserver.

If I reboot, will I lose all the data in the fossil
write cache and/or the venti snapshot?

no, fossil is very good at suffering reboots (assuming something has gotten to fossil, but otherwise you wouldn't have a running system, right!?)

try mounting fossil's snapshot and archive again and see if they're alive and well, try connecting to the console (con -l /srv/fscons, if you've followed the wiki instructions closely) -- the vac score may be buffered there still. 9fs dump doesn't show you anything?

I don't think you will loose any data; anyway, is the console
alive? I'm wondering what happen to your machine.

Everything is fine. Somehow, everything rebooted while I
was gone -- probably a power outage. I normally run clog
to capture the fossil console, but it doesn't get restarted
on boot. I have the vac score.

Thanks for the help.
