the nfs share can be manually mount in the pve host by command "mount -t nfs4 172.16.0.31:/export/nfs-pve" , but auto mount failed.

nfs share is configured in cluster - storage.

nfs server side option is anongid=100, anonuid=100, insecure, no_root_squash, rw, subtree_check

there are 6 nodes in cluster ( going to replace a old node with pve-5. other 5 nodes can mount the nfs share automatically. )
 
Hi,
please share the output of cat /etc/pve/storage.cfg and the relevant line from cat /proc/mounts on a node where the mount does work. Does that node run the same kernel and same version of libpve-storage-perl?
 
libpve-storage-perl are same. node 1/2/3/4/6 have upgrade to same version, but did not reboot yet ( the omv-1 nfs share has mounted 200+ days on 1/2/3/4/6 nodes). nfs server is openmediavault 6.

The version is set to 4.2 in the configuration.

Code: 
172.16.0.31:/export/nfs-pve /mnt/pve/omv-1 nfs rw,relatime,vers=3,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,mountaddr=172.16.0.31,mountvers=3,mountport=42016,mountproto=udp,local_lock=none,addr=172.16.0.31 0 0
But it's mounted with vers=3 on the node pve-4. Are you sure it supports version 4.2? Did you change the configuration recently?

yes, server is omv6, on nfs server :
root@omv-1:~# cat /proc/fs/nfsd/versions
-2 +3 +4 +4.1 +4.2

server has not upgrade recently, have tried recreate export rule. (same parameter as before), that is after issue noticed. assigned to 172.16.2.0/29.
 
after change version to 3 in cluster storage, now pve-5 nfs mount works. thank you @fiona .

seems is omv side issue, test on my station it's actually v3. v4 not work either.
