kernel: NFSD: client testing state ID with incorrect client ID

Post by pharthiphan » 2021/02/03 07:31:32

I see couple of clients showing up on the nfs server system messages as "incorrect client ID" and I don't see much on the client system logs.

I have a nfs server running on centos 7 and client's are ubuntu but only these two clients have some clients on nfs server logs

Code: Select all

grep "incorrect client ID" /var/log/messages | awk '{$1=$2=$3=$4=""; print $0}' | sort | uniq -c
   5504     kernel: NFSD: client 10.52.104.56 testing state ID with incorrect client ID
   7966     kernel: NFSD: client 10.52.104.57 testing state ID with incorrect client ID

below outputs from the client node:-

Code: Select all

# mount -t nfs4
