Bacula on FreeBSD (Part 3 storage setup)
I finally got the time to continue with my bacula backup setup. See my previous posts about the start of my bacula setup.
Storage setup
I created a new zfs pool “bigpool” with some old harddisks I probably need to replace them with bigger harddisk in the further.
zfs filesystem
First we create a zfs filesystem for our bacula storage.
root@rataplan:~ # zfs create bigpool/bacula
root@rataplan:~ #
delegate to jail
jailed
We want to use the zfs dataset in the bacula jail so we need to delegate the control to the dataset into the bacula jail.
root@rataplan:~ # zfs set jailed=on bigpool/bacula
root@rataplan:~ # zfs jail stafbacula bigpool/bacula
verify
When we logon to the jail we see that the zfs dateset is available.
root@rataplan:~ # ezjail-admin console stafbacula

root@stafbacula:~ # zfs list
no datasets available
root@stafbacula:~ #
make persistent
enable zfs in the jail
When the jail is booted it need to bring the zfs filesystem online. We need to add zfs_enable=YES to the jail rc.conf
root@rataplan:~ # vi /usr/jails/stafbacula/etc/rc.conf
bacula_dir="start"
bacula_dir_enable="yes"
zfs_enable="YES"
update the ezjail configuration
ezjail needs to jail the zfs dataset to the jail when it’s start the jail.
root@rataplan:~ # vi /usr/local/etc/ezjail/stafbacula
We need to add the dataset to the jail’s zfs_datasets. By default a jail isn’t allowed to mount the zfs dataset so need to update jail’s parmeters.
export jail_stafbacula_zfs_datasets="bigpool/bacula"
export jail_stafbacula_parameters="enforce_statfs=0 allow.mount=1 allow.mount.zfs=1 allow.mount.procfs=1 allow.mount.devfs=1"
Restart the jail and verify that the zfs filesystem is available inside the jail
root@rataplan:~ # ezjail-admin restart stafbacula
Stopping jails: stafbacula.
Starting jails: stafbacula.
/etc/rc.d/jail: WARNING: Per-jail configuration via jail_* variables is obsolete. Please consider migrating to /etc/jail.conf.
root@rataplan:~ #
Verify that dataset is mounted
