Cluster backup: NFS mount point

gauresh_shinde — Tue, 20 Jun 2023 12:58:33 GMT

Hi All,

We are trying to configure cluster backup. We have 3 node cluster setup.

/DT_Backup is mounted as local partition on one node server and the same has been configured as nfs mount point on the other 2 node servers. But it is not working getting network error.

Need your help

Thanks

The configuration test that is made tried to create a temp file in the directory, read and remove it. The test is done from each cluster node. If there's a network error, it means a node can't perform such an operation. Ensure you've mounted the NFS storage on all nodes properly, and check directory permissions (so `dynatrace` user has access to it), ownership, and the network.

Hi @gauresh_shinde ,

you can check the backup and restore mentioned by Islam Zidan here.

and if you are still facing some errors/issues, I would suggest to open a support ticket and try to include the errors and logs related to the issue

On our managed instance we had a NFS Mount point for all 3 clustered nodes where the backup would reside. The only issue we ran into was permissions. Make sure you have 777 for Linux across the board.
