Hi Alexey,

thanks for a tip. No, define sec=... in /etc/nfsmount.conf does not help.

* Adding sec=sys into /etc/nfsmount.conf leads to (or keeping the default):
nfs01 1 TINFO: Mounting NFS: mount -t nfs -o proto=tcp,vers=4.1 10.0.0.2:/tmp/LTP_nfs01.nM6Epvvg20/4.1/tcp /tmp/LTP_nfs01.nM6Epvvg20/4.1/0
mount.nfs: mounting 10.0.0.2:/tmp/LTP_nfs01.nM6Epvvg20/4.1/tcp failed, reason given by server: No such file or directory
nfs01 1 TBROK: mount command failed

* sec=none

* sec=krb5 or sec=krb5i or sec=krb5p

mount.nfs: an incorrect mount option was specified

I have to dig more into the docs.

BTW what services are required to be running for NFS tests?
I have running: proc-fs-nfsd.mount, var-lib-nfs-rpc_pipefs.mount, nfs-idmapd.service, nfs-mountd.service, nfs-server.service, nfsdcld.servicenfs-client.target.

Kind regards,
Petr
