Charlie - ZFS Bitrot
- 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!
