Hi all,
I've got an interesting (I think) thing happening with my storage pool
(tank, 8x1.5TB RAID-Z2)...namely that I seem to gain free-space
without deleting files. I noticed this happening awhile ago, so I set
up a cron script that ran every night and does:
pfexec ls -alR /tank
Huh, I don't actually ever recall enabling that. Perhaps that is
connected to the message I started getting every minute recently in
the kernel buffer,

Argh, yes, lots of snapshots sitting around...apparently time-slider

cleaning out the snapshots!

Where would that log be located? Tried poking around in /var/svc/log

useful, they don't seem to have logged the auto-deletion of

Interesting, I didn't realize that Soracle was working on/had a
solution somewhat in place for 4K-drives. I wonder what will happen
