I haven't run ZFS + LUKS but I'm running ZFS Native Encryption.

There is an outstanding issue [0] that I've encountered on two separate machines running in this setup. The issue occurs when using ZFS Native Encryption + (NVMe?) SSDs. The issue appears to be snapshots getting corrupted (or maybe failing to create?) occasionally. It happens roughly 1/1000 snapshots in my case. I take a lot of snapshots so this occurs weekly.

I haven't lost any data yet but this issue is annoying because I get spooky alerts from ZFS warning me about "potential data corruption". To clear them I have to manually intervene by deleting the corrupt snapshots, restart the machine, then scrub.

What's most annoying is that this breaks ZFS send/recv until I intervene. send/recv was the whole reason I went with native encryption instead of LUKS in the first place.

Again, no data corruption so far (if you don't count the snapshots that get lost, which I don't, because I have so many of them). Just very annoying and tedious.
