https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D233113 Bug ID: 233113 Summary: bectl activate fails to set canmount=3Dnoauto for old boot environment Product: Base System Version: 12.0-STABLE Hardware: Any OS: Any Status: New Severity: Affects Many People Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: asomers@FreeBSD.org "bectl activate" is supposed to set canmount=3Dauto for the old boot enviro= nment and set the pool's bootfs property to the new boot environment. That's what beadm does. However, bectl fails to clear canmount for the old boot environment. Observed on 12.0-BETA3 Example: somers@threonine /> bectl list BE Active Mountpoint Space Created 12.0-BETA4 NR / 9.45G 2018-11-10 10:09 12.0-BETA3 - - 1.52M 2018-11-08 09:35 12.0-CURRENT-up-20180401_231457 - - 38.0G 2018-04-01 23:13 12.0-CURRENT-up-20180327_233010 - - 13.2G 2018-03-27 23:28 somers@threonine /> zfs list -o name,mountpoint,canmount -r tank/ROOT NAME MOUNTPOINT CANMOUNT tank/ROOT none on tank/ROOT/12.0-BETA3 / noauto tank/ROOT/12.0-BETA4 / on tank/ROOT/12.0-CURRENT-up-20180327_233010 / noauto tank/ROOT/12.0-CURRENT-up-20180401_231457 / noauto somers@threonine /> sudo bectl create test somers@threonine /> sudo bectl activate test successfully activated boot environment test somers@threonine /> zpool get bootfs tank NAME PROPERTY VALUE SOURCE tank bootfs tank/ROOT/test local somers@threonine /> zfs list -o name,mountpoint,canmount -r tank/ROOT NAME MOUNTPOINT CANMOUNT tank/ROOT none on tank/ROOT/12.0-BETA3 / noauto tank/ROOT/12.0-BETA4 / on tank/ROOT/12.0-CURRENT-up-20180327_233010 / noauto tank/ROOT/12.0-CURRENT-up-20180401_231457 / noauto tank/ROOT/test / noauto !!!! 12.0-BETA4 still has CANMOUNT set to on !!!! But beadm has no problem here: somers@threonine /> sudo beadm activate 12.0-BETA4 Activated successfully somers@threonine /> sudo beadm destroy test Are you sure you want to destroy 'test'? This action cannot be undone (y/[n]): y Destroyed successfully somers@threonine /> zfs list -o name,mountpoint,canmount -r tank/ROOT NAME MOUNTPOINT CANMOUNT tank/ROOT none on tank/ROOT/12.0-BETA3 / noauto tank/ROOT/12.0-BETA4 / on tank/ROOT/12.0-CURRENT-up-20180327_233010 / noauto tank/ROOT/12.0-CURRENT-up-20180401_231457 / noauto somers@threonine /> sudo beadm create test Created successfully somers@threonine /> sudo beadm activate test Activated successfully somers@threonine /> zpool get bootfs tank NAME PROPERTY VALUE SOURCE tank bootfs tank/ROOT/test local somers@threonine /> zfs list -o name,mountpoint,canmount -r tank/ROOT NAME MOUNTPOINT CANMOUNT tank/ROOT none on tank/ROOT/12.0-BETA3 / noauto tank/ROOT/12.0-BETA4 / noauto tank/ROOT/12.0-CURRENT-up-20180327_233010 / noauto tank/ROOT/12.0-CURRENT-up-20180401_231457 / noauto tank/ROOT/test / noauto This bug renders the new boot environment unbootable, because two root filesystems get mounted, making devfs invisible. So it's a pretty critical bug. --=20 You are receiving this mail because: You are the assignee for the bug.=
