The solution:
given each pool has a seperate IP adress through pacemaker
FDAddresses = {
ip = { addr = XX.XXX.XXX.XXX; port = 9102; }
}
add this to the filedaemon config
and add pacemaker filedaemon resource to zfs pool group
then the syetemd config of the pools filedaemon has to be modified, you
need a new /etc/bareos-POOLNAME folder for each pool
[Unit]
Description=Bareos File Daemon service tank03
Documentation=man:bareos-fd(8)
Requires=network.target nss-lookup.target time-sync.target
After=network-online.target nss-lookup.target remote-fs.target
time-sync.target
[Service]
Type=simple
User=root
Group=bareos
WorkingDirectory=/var/lib/bareos
ExecStart=/usr/sbin/bareos-fd -c /etc/bareos-POOLNAME-f
SuccessExitStatus=0 15
Restart=on-failure
# IOSchedulingClass=idle
[Install]
Alias=bareos-fd-POOLNAME.service
WantedBy=multi-user.target
this setup works great, much better than backing up through NFS and you get
acess to snapshots
