Hello ,

I am trying to setup NFS export but doesn't seem to work. It's an upgraded version of petasan.

This is the error:

Logs in petasan.log

This is my current config:

Any idea?

Edit: Solved by reducing the number of IP's configured in NFS settings to 5.

Thanks for the update.

We fire up a ganesha nfs container for each nfs service ip, this is how the mltiheaded active/active ganesha ceph is designed. This could put resource load if you have a lot of ips.

Since 3.0 we put a limit of 5 ips per nfs service node, this is done at the ui level to limit resource usage, as we noticed higher usage in Ubuntu 20.04 from 18.04 when using ganehsa containers. If you had entered more than 5 per node from a previous version, it should be ok if resources are fine. But 5 should be enough per node, the reason to have more than 1 ip per node is to give better load distribution in case a node goes down, it will distribute its load to more than one active node.
