I created a ZFS pool using 11.2 and put several filesystems on it. Following end of support for 11.2 around Halloween, I built another machine (soho2) with FreeBSD 11.3 RELEASE and created a ZFS pool using 11.3. I replicated the filesystems from soho to soho2, migrated services, and shelved soho. Last month, I put a blank system drive in soho and installed FreeBSD 11.3 RELEASE. I have noted messages about the previously existing ZFS pool: 2020-01-07 19:56:38 toor@soho ~ # zpool status p1 pool: p1 state: ONLINE status: Some supported features are not enabled on the pool. The pool can still be used, but some features are unavailable. action: Enable all features using 'zpool upgrade'. Once this is done, the pool may no longer be accessible by software that does not support the features. See zpool-features(7) for details. scan: scrub repaired 0 in 0 days 02:29:34 with 0 errors on Sun Aug 18 14:59:03 2019 config: NAME STATE READ WRITE CKSUM p1 ONLINE 0 0 0 mirror-0 ONLINE 0 0 0 gpt/p1a.eli ONLINE 0 0 0 gpt/p1b.eli ONLINE 0 0 0 errors: No known data errors One of the drives in soho2 has failed, so I am now trying to replicate the filesystems from soho2 back into soho. Replication works for smaller snapshots, but larger snapshots that take ~10 minutes or more cause a panic and reboot. /var/log/messages from today has some examples: http://holgerdanske.com/pub/dpchrist/issue/freebsd-11.3/20200107-panic/var-log-messages.log How do I troubleshoot this?
