https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D273772 --- Comment #11 from Marek Zarychta <zarychtam@plan-b.pwste.edu.pl> --- Now both: bhyve host and guest are running FreeBSD stable/14. ZFS pools on = host and guest were upgraded. The report is still valid and the issue is persist= ent. Maybe the transition to mirror (the guest is nested on a ZVOL of pool with= a top-level-vdev that had previously been removed) has something to do with it (see bug 273663). The guest is using host's ZVOL zroot/ZVOL/virtbsd as vtbd= 0. This is how ZFS looks on the host:=20 # zpool status zroot pool: zroot state: ONLINE scan: scrub repaired 0B in 00:11:06 with 0 errors on Fri Jan 26 03:21:55 = 2024 scan warning: skipped blocks that are only referenced by the checkpoint. remove: Removal of vdev 1 copied 15.1G in 0h0m, completed on Fri May 15 20:04:34 2020 119K memory used for removed device mappings checkpoint: created Mon Dec 4 20:10:12 2023, consumes 49.6G config: NAME STATE READ WRITE CKSUM zroot ONLINE 0 0 0 mirror-0 ONLINE 0 0 0 da0p2 ONLINE 0 0 0 da1p2 ONLINE 0 0 0 errors: No known data errors # zpool get all zroot NAME PROPERTY VALUE SOURCE zroot size 476G -
