Hi All
I noticed from discussions on this forum that @Arwen is using ZFS on her linux laptop, so I decided to give ZFS on linux a shot for my home desktop PC. So far so good, but what about interoperability with FreeNAS ZFS.
Since ZFS is coming from two development streams (FreeBSD/Linux Debian/Ubuntu) am I likely to run into problems if I want to send/receive ZFS snapshots (for backup/restore)? Does anyone have experience doing this? Am I likely to corrupt a pool doing this?
Maybe someone familiar with the process/politics of the upstream development could comment on the likelihood of long term compatibility?
I've included some details of my current ZFS implementations below. Any guidance, suggestions or references on the web would be most helpful.
