What to do about it?

No response

HI @UAnton ,

This error occurs when there is a mismatch in the NFS versions that cloudstack is trying to mount and the version that you are using on the nfs server.

Please check the nfs version mentioned in your Configuration "secstorage.nfs.version"

Also check if the nfs server is running on a higher version only

you can check the version of nfs on the server using

rpcinfo -p

Please make sure that version matches in cloudstack and nfs server

@nischalnischal2020 Hi,
nfs-server version is 3.

secstorage.nfs.version

[nischalnischal2020]

Hi @UAnton

Can you please manually mount the nfs share on the KVM hosts and check if it works?

[UAnton]

Hi @nischalnischal2020,
Yes, share is work but with -o vers=3

I found a solution how to enable v4 on my old VNXe3200.
