John,

Have you set the global settings parameter secstorage.nfs.version?

I had to set it as 3 for my environment as NFS4 isn’t used yet.  However, I’m using an
external storage system, not KVM as the NFS host.

Subject: NFS Error Ubuntu 20.4

We are having some issues with the latest CS 4.15.1 which we never had before.

We are using the following:-
Ubuntu 20.4
CS 4.15.1

NFS is on the same host as the KVM server.
We can mount the /export/secondary directory successfully from the management host.
But when CS tries to mount it we get this error is the management log.

Unable to mount XXX.XXX.XXXX:/export/secondary at /mnt/SecStorage/4891ed6e-23b4-3b63-a190-1298ce00ed8d
due to mount.nfs: access denied by server while mounting XXX.XXX.XXXX:/export/secondary

Further, as we are using the KVM host as the NFS server do we need to install NFS on the management
host as well as the KVM host ?

Here is some further logs which may assist.

Any tips would be helpful.
