Hello,

is there any possibility to do Bacula backup jobs only in case a
directory exists/is mounted?

We are using DRBD on a 2 node cluster. Usually the first node is
active and the backup job is running on this node. In case we have to
do a failover we don't have a backup. I created a job for the second
node but now we receive all the time warnings because the filesystem
is only mounted when the second node will be promoted to DRBD-Primary.

In most HA clusters you should have a cluster service IP address (failover) which is pointing to the active node (the node where cluster serice is active). This IP address should failover with your cluster service. In this case you can define a virtual bacula client (at cluster service IP address) which will be responsible for cluster service backup. To assure your virtual bacula client can successfully connect to the bacula service is to define the same bacula client password for both nodes. See simple configuration:

FD:

Node1:

- ip: 10.10.10.10

- passwd: baculapassword

Node2:

- ip: 10.10.10.20

- passwd: baculapassword

Cluster Service:

- ip: 10.10.10.30

DIR:

 

client { name=node1; address=10.10.10.10; password=baculapassword; }

client { name=node2; address=10.10.10.20; password=baculapassword; }

client { name=cluster1; address=10.10.10.30; password=baculapassword; }

I hope this help.

 best regards
