https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D275870 Bug ID: 275870 Summary: [unionfs] [zfs] kernel panic on umount Product: Base System Version: 14.0-RELEASE Hardware: Any OS: Any Status: New Severity: Affects Many People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: karlo98.m@gmail.com If you do a ZFS rollback which removes a unionfs mountpoint and umount mountpoint after that, 14.0 kernel will panic. In 13.0 it works fine - it is unmounted even though the directory was rolled back. I provide a small script that reproduces the problem: #!/bin/sh zfs create zroot/var/repro zfs snapshot zroot/var/repro@clean cd /var/repro mkdir a b mount_unionfs a b zfs rollback zroot/var/repro@clean umount /var/repro/b --=20 You are receiving this mail because: You are the assignee for the bug.=
