Those compatibility flags, mirror the pool create options I noted above... With doing a snapshot of bpool, and Send'ing it 'somewhere', even if that was to a flash-drive... Destroying the original bpool, recreate the new bpool, then Receive, the snapshot back to restore it, does fix that with less than 2GB of storage.
That is just one work-around. I've started (manually) making bpool's 3GB on ZFS-On-Root installs, to allow more room for my snapshots... Upgrading Grub2 to 2.12, from 2.12rc and previous, fixes the problem also. There is 3-4 work-around listed in this report that works. ----------------------------------------------------------------------- Sideline Note: Someone (wprince) contacted me via email asking for assistance on their company's production email server being affected by this bug.
