How to fix fatal: Unable to create lock file: No locks available (NFS filesystem) in Git

# Check mount options for all NFS mounts
mount | grep nfs

# Or check a specific mount point
mount | grep /path/to/your/repo

# Look for 'nolock' in the output - if present, locking is disabled
# Example output with locking disabled:
# server:/export on /mnt/nfs type nfs (rw,nolock,addr=192.168.1.100)

cat /proc/mounts | grep nfs

# Unmount the NFS share (ensure no processes are using it)
sudo umount /mnt/nfs

# Remount with locking enabled (remove nolock option)
sudo mount -t nfs -o rw,hard,intr server:/export /mnt/nfs

# Or if using NFSv4:
sudo mount -t nfs4 -o rw,hard,intr server:/export /mnt/nfs

# Before (locking disabled):
server:/export  /mnt/nfs  nfs  rw,nolock  0  0

# After (locking enabled - remove nolock):
server:/export  /mnt/nfs  nfs  rw,hard,intr  0  0

sudo mount -o remount /mnt/nfs

# Check status of NFS client services
sudo systemctl status nfs-client.target
sudo systemctl status rpc-statd

# Start and enable the services
sudo systemctl enable rpc-statd
sudo systemctl start rpc-statd

# For some distributions, you may also need:
sudo systemctl enable nfs-lock
sudo systemctl start nfs-lock

# Restart NFS client services to apply
sudo systemctl restart nfs-utils

# Check if services are running
service nfslock status
service rpcbind status

# Start the services
sudo service rpcbind start
sudo service nfslock start

# Enable at boot
sudo chkconfig rpcbind on
sudo chkconfig nfslock on

rpcinfo -p | grep -E 'nlockmgr|status'
# You should see entries for nlockmgr (lockd) and status (statd)

# Check current firewall rules
sudo firewall-cmd --list-all

# Add NFS and related services
sudo firewall-cmd --permanent --add-service=nfs
sudo firewall-cmd --permanent --add-service=rpc-bind
sudo firewall-cmd --permanent --add-service=mountd

# Reload firewall
sudo firewall-cmd --reload

# Allow NFS-related traffic
sudo iptables -A INPUT -p tcp --dport 111 -j ACCEPT
sudo iptables -A INPUT -p udp --dport 111 -j ACCEPT
sudo iptables -A INPUT -p tcp --dport 2049 -j ACCEPT
sudo iptables -A INPUT -p udp --dport 2049 -j ACCEPT

# Mount using NFSv4 explicitly
sudo mount -t nfs4 server:/export /mnt/nfs

# Or specify version in mount options
sudo mount -t nfs -o vers=4,rw,hard,intr server:/export /mnt/nfs

server:/export  /mnt/nfs  nfs4  rw,hard,intr  0  0

nfsstat -m
# Look for "vers=4" in the output

# On the NFS server
cat /proc/fs/nfsd/versions
# Should show +4 or +4.1 for NFSv4 support

# Clone to local filesystem
git clone https://github.com/user/repo.git ~/local-repo

# Work locally, then sync to NFS for backup/sharing
rsync -av --exclude='.git' ~/local-repo/ /mnt/nfs/repo/

# Keep the .git directory on local storage
mkdir -p ~/git-storage/myrepo.git
git clone --bare https://github.com/user/repo.git ~/git-storage/myrepo.git

# Create a worktree on NFS for the files
git -C ~/git-storage/myrepo.git worktree add /mnt/nfs/myrepo main

# Move .git to local storage
mv /mnt/nfs/repo/.git ~/local-git-storage/repo.git

# Create symlink
ln -s ~/local-git-storage/repo.git /mnt/nfs/repo/.git

# Set index to local filesystem
export GIT_INDEX_FILE=/tmp/git-index-$(basename $(pwd))

# Now run Git commands
git status
git add .
git commit -m "message"

#!/bin/bash
# Save as ~/bin/nfs-git

# Generate unique index path based on repo location
REPO_HASH=$(echo "$PWD" | md5sum | cut -d' ' -f1)
export GIT_INDEX_FILE="/tmp/git-index-$REPO_HASH"

# Run git with all passed arguments
git "$@"

cat /etc/exports
# Example entry:
# /export  192.168.1.0/24(rw,sync,no_subtree_check)

sudo exportfs -ra
sudo systemctl restart nfs-server

sudo systemctl status nfs-server
sudo systemctl status rpc-statd

# Verify lock manager is registered
rpcinfo -p | grep nlockmgr
