Oops, I meant SHA256. My mind just maps SHA-SHA1, totally forgetting that ZFS

In general, yes. But it is complaining about corrupted data, which can
be due to another failure.
Any suggestions on how to discover what that failure might be?

A snapshot is a picture of the storage at a point in time so
everything depends on the applications using the storage. If you're
running a db with lots of cache it's probably a good idea to stop the
service or force a flush to disk before taking the snapshot to ensure
the integrity of the
If you're concerned about someone reading the charge level of a Flash cell to
infer the value of the cell before being erased, then overwrite with random
data twice before issuing TRIM (remapping in an SSD probably makes this
ineffective).

This probably the best answer right now. It will be even better when they get a

possible.

ZFS will not lose data during a snapshot.

Yes, all ZFS data will be committed to disk and then
Hi,
(Main questions at bottom of post)
I recently discovered the joys of ZFS. I have a home file server for
backups+media, also hosting some virtual machine (over LAN).
I was wondering if I could get some feedback as to whether I have set things up
properly.

The advantage of TRIM, even in high end SSDs, is that it allows you to

- The SSD cannot know which blocks are currently not in use.
It does know that blocks in its spare pool are not in use.
