Good morning guys,
We have a situation about CS and NFS, we are trying to make some
customizations with CS 4.17 parameters when mounting NFS server from
hosts with version 4 and we can see that this feature is working on
4.19.1, so, we make a lab with 4.17 and upgrade it to 4.19.1.
When we do this, see that CS 4.19.1 changes the type option in the mount
command and mount the resources in nfs3 for default, this is very
serious altough is a lab so we continue with the tests.
*/Mounted command with CS 4.17 (working)
/*
/10.0.10.102:/cloudstack on /mnt/4c524bab-25a3-3db5-a665-d37159b81f11
*type nfs4
*(rw,nosuid,nodev,noexec,relatime,*vers=4.2*,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,clientaddr=10.0.10.33,local_lock=none,addr=10.0.10.102)/
*/Mounted command with CS 4.19.1 (working but nfs3)
/*
/10.0.10.104:/cloudstack on /mnt/1a5453f8-0ddc-395c-bafc-1e196b4e7269
*type nfs*
(rw,nosuid,nodev,noexec,relatime,*vers=3*,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,mountaddr=10.0.10.104,mountvers=3,mountport=51219,mountproto=udp,local_lock=none,addr=10.0.10.104)/
Then we try to force nfs version to 4 wth the parameters that suggest in
the web
(https://docs.cloudstack.apache.org/en/4.19.1.0/adminguide/storage.html#storage-tags)
and doesn't work.

The nfs server is the same with same configuration in the 3 tests, so we
can't understand the failure. Can you help us with this?-
Regards,
