Nfs Vlted | 45 Work

The fix? VMware ESXi’s NFS client defaults to NFSv4.1. The NetApp filer was still on NFSv4.0. Error 45 appeared due to unsupported RECLAIM_COMPLETE operation.

| Practice | Why It Helps | |----------|---------------| | | Most mature, fewer unsupported ops. | | Keep kernel & nfs-utils in sync on client/server | Error 45 often appears after partial updates. | | Test new mount options with -o noac,vers=4.2 first | Exposes unsupported features early. | | Use nfsstat regularly | nfsstat -c -v shows per-operation error counts. | | When upgrading servers, enable debugging | echo 32767 > /proc/sys/sunrpc/rpc_debug (temporary). | Conclusion: Your "NFS VLTED 45" Checklist The phrase "nfs vlted 45 work" may be awkward and misspelled, but it points to a real, solvable issue: NFSv4.1+ returning ENOTSUP (Error 45) for unsupported operations.

On the client (as root):

uname -r If < 4.15, upgrade or disable pNFS with -o nopnfs . When the basic steps fail, get surgical. Use tcpdump to see the actual NFS call that returns error 45 .

# Remount with NFSv4.0 only sudo mount -t nfs -o vers=4.0 server:/export /mnt/nfs sudo mount -t nfs -o vers=3 server:/export /mnt/nfs nfs vlted 45 work

yum update kernel nfs-utils For Ubuntu 16.04 (obsolete but still used):

# Check kernel messages dmesg | grep -i nfs | grep -i "45" mount | grep nfs Run a controlled test with verbose output mount -t nfs -o vers=4,verbose server:/export /mnt/test The fix

apt-get install --install-recommends linux-generic-hwe-16.04 A specific bug that caused error 45 on READDIR with pNFS was fixed in . Check your version:
