how does geli interact with ZFS?

[Michal-50]

Hello,

I'm using root ZFS on geli encrypted partition (with /boot on UFS usb
dongle). Does adding this extra layer between ZFS and disk can get me
into troubles in case of a system crash?
I mean, does it affects zfs's robustness and features like
Copy-On-Write, checksumming or anything else? Or it can only get as bad
as with plain ZFS and geom_eli has nothing to do with that.

I use ZFS on top of geli encrypted slice for at least a year and never
had problems related to such setup. In my case it's not root
partition (however / is ZFS as well), it's my laptop, so I can't tell
you how does it behave during long uptimes.

GELI will do its work, and ZFS will do its work. Apart from natural
loss of speed, there's no difference in functioning of ZFS on bare
disk or GELI provider.
