The backup operation fails with the following error:
~# vzabackup localhost -e 2343 Starting backup operation for node 'vz.example.com'... * Operation with the Container examplect.com is started * Operation with the Container examplect.com is finished with errors: Master is not accessible. Backup operation for node 'vz.example.com' failed: Master is not accessible Backup failed
The node is a slave in PVA group and the PVA master server is not accessible.
Check if the node is master or slave using the command "vzagroup list":
~# vzagroup list Connecting to local host... Resolving host's group role... host is a slave in vzgroup, which master node address is 192.168.34.12
Check if the master node is accessible from the local server with
~# ping 192.168.34.12 ~# telnet 192.168.34.12 4534
Ensure that connections are not blocked on all ports needed for PVA MN and slave nodes.
Make sure there is no discrepancy in major versions of PVA Agent and PVA Management Node. To check the version that is currently installed:
~# rpm -q pva-release
