Resolution
Workaround
If update is not possible for some reason you may try the following
temporary solution
Connect to the server via SSH and use one of the following workarounds:
Workaround 1. Re-mount NFS storage as NFS3 storage using these commands:
# umount /mnt/share
# mount -t nfs -o vers=3 SERVER:PATH /mnt/share
Workaround 2. Disable idmapping for nfs4 share:
# echo “options nfs nfs4_disable_idmapping=1” >> /etc/modprobe.d/nfs.conf
