Charlie - ZFS Bitrot

Gents,

Thanks so much for the show. I've been a listener since episode #1, and
it has been such a great resource in sharpening my *BSD know-how.

Following in the footsteps of Jupiter Broadcasting's own Chris Fisher,
my wife and I are living full-time in a RV. (And we're throughly
enjoying it for anyone who is curious - its not as bad as you'd think!)

With our new living arrangement, I am slightly more concerned about
physical security than I was previously. It would not take much to break
into an RV and quickly make off with any valuables.

Therefore, I'd like to encrypt all my critical data. Currently, I have a
small file server running ZFS with no disk encryption. Disks are
arranged in a "RAID-10" style configuration (data striped over two
mirrored pairs).

My question to you is this: if I use GELI-encrypted disks as the
foundation for my new pool, what happens if a "flipped bit" or other
corruption condition occurs? Is ZFS on top of GELI just as "safe" from a
data corruption standpoint as ZFS on a raw disk, even though ZFS cannot
"reach down" into the GELI layer?

Thanks for shedding light on this. I hear about encrypted ZFS pools
quite frequently, so I'm assuming its relatively safe, but I want to
make sure I'm not missing anything before I take the plunge.

Keep up the great work!

Charlie
