I encounter no problems when starting the jails post-boot. I added logging to /etc/rc.d/jail in a similar manner to the original poste= r, and see this output: ---- mount_nullfs: /jails/pgsql/data: mount_nullfs: /jails/hg/data: Operation not supported by device Operation not supported by device jail: pgsql: /sbin/mount -t nullfs -o rw /data/pgsql /jails/pgsql/data: fai= led jail: hg: /sbin/mount -t nullfs -o rw /data/hg /jails/hg/data: failed jail: support: skipped jail: logic: skipped www-bhs-0: created backup-bhs-0: created ... ---- Here is my jail.conf: ---- # START BLOCK: Araxis jail defaults -- DO NOT EDIT exec.start =3D "/bin/sh /etc/rc"; exec.stop =3D "/bin/sh /etc/rc.shutdown"; exec.clean; mount.devfs; mount.fdescfs; allow.noset_hostname; host =3D new; # temporarily allow during development/testing allow.raw_sockets; # END BLOCK: Araxis jail defaults # START BLOCK: Araxis jail settings for jail www-bhs-0.araxis.net -- DO NOT EDIT www-bhs-0 { mount.fstab =3D "/jails/.fstabs/www-bhs-0"; path =3D "/jails/www-bhs-0"; host.hostname =3D www-bhs-0.araxis.net; ip4.addr =3D "lo1|10.11.11.2/32"; ip6.addr =3D "ix0|2607:5300:60:9b9c::2/64"; } # END BLOCK: Araxis jail settings for jail www-bhs-0.araxis.net # START BLOCK: Araxis jail settings for jail backup-bhs-0.araxis.net -- DO = NOT EDIT backup-bhs-0 { mount.fstab =3D "/jails/.fstabs/backup-bhs-0"; path =3D "/jails/backup-bhs-0"; host.hostname =3D backup-bhs-0.araxis.net; ip4.addr =3D "lo2|10.12.12.8/32"; enforce_statfs =3D 1; allow.mount; allow.mount.zfs; exec.poststart =3D "/sbin/zfs set jailed=3Don zroot/bkup && /sbin/zfs jail ${name} zroot/bkup && jexec ${name} /sbin/zfs mount -a"; exec.prestop =3D "/sbin/zfs unjail ${name} zroot/bkup && /sbin/zfs set jailed=3Doff zroot/bkup"; } # END BLOCK: Araxis jail settings for jail backup-bhs-0.araxis.net # START BLOCK: Araxis jail settings for jail pgsql.araxis.net -- DO NOT EDIT pgsql { mount.fstab =3D "/jails/.fstabs/pgsql"; path =3D "/jails/pgsql"; host.hostname =3D pgsql.araxis.net; ip4.addr =3D "lo2|10.12.12.4/32"; allow.sysvipc; } # END BLOCK: Araxis jail settings for jail pgsql.araxis.net # START BLOCK: Araxis jail settings for jail support.araxis.net -- DO NOT E= DIT support { mount.fstab =3D "/jails/.fstabs/support"; path =3D "/jails/support"; host.hostname =3D support.araxis.net; ip4.addr =3D "lo2|10.12.12.5/32"; depend =3D pgsql; } # END BLOCK: Araxis jail settings for jail support.araxis.net # START BLOCK: Araxis jail settings for jail logic.araxis.com -- DO NOT EDIT logic { mount.fstab =3D "/jails/.fstabs/logic"; path =3D "/jails/logic"; host.hostname =3D logic.araxis.com; ip4.addr =3D "lo2|10.12.12.6/32"; depend =3D pgsql; } # END BLOCK: Araxis jail settings for jail logic.araxis.com # START BLOCK: Araxis jail settings for jail hg.araxis.net -- DO NOT EDIT hg { mount.fstab =3D "/jails/.fstabs/hg"; path =3D "/jails/hg"; host.hostname =3D hg.araxis.net; ip4.addr =3D "lo2|10.12.12.3/32"; } # END BLOCK: Araxis jail settings for jail hg.araxis.net ---- The various fstab files are nearly identical.
