## Configuration Files
|
||
- **/etc/exports** - NFS export definitions (currently empty)
|
||
- **/etc/idmapd.conf** - NFSv4 ID mapping configuration
|
||
- **/etc/nfs.conf** - NFS server configuration
|
||
- **/etc/default/nfs-kernel-server** - NFS kernel server defaults
|
||
|
||
## Export Configuration
|
||
Currently no exports configured. Export list is empty:
|
||
\\\ash
|
||
showmount -e localhost
|
||
# Export list for localhost:
|
||
\\\
|
||
|
||
## Next Steps for NFS Share Configuration
|
||
|
||
### 1. Create NFS Export
|
||
Edit /etc/exports to add shared directories:
|
||
\\\ash
|
||
# Example exports
|
||
/data/nfs-share 192.168.1.0/24(rw,sync,no_subtree_check)
|
||
/backup 10.10.14.0/24(ro,sync,no_root_squash)
|
||
\\\
|
||
|
||
### 2. Apply Exports
|
||
\\\ash
|
||
exportfs -a # Apply all exports
|
||
exportfs -v # Verify exports
|
||
systemctl restart nfs-server
|
||
\\\
|
||
|
||
### 3. Firewall Rules (if needed)
|
||
\\\ash
|
||
ufw allow from 192.168.1.0/24 to any port nfs
|
||
ufw allow 2049/tcp # NFS
|
||
ufw allow 111/tcp # RPC portmapper
|
||
ufw allow 111/udp # RPC portmapper
|
||
\\\
|
||
|
||
### 4. Test Mount (from client)
|
||
\\\ash
|
||
showmount -e 10.10.14.16
|
||
mount -t nfs 10.10.14.16:/data/nfs-share /mnt/nfs
|
||
\\\
|
||
|
||
## NFS Export Options Reference
|
||
- **rw**: Read-write access
|
||
- **ro**: Read-only access
|
||
- **sync**: Synchronous writes (safer, slower)
|
||
- **async**: Asynchronous writes (faster, less safe)
|
||
- **no_subtree_check**: Disable subtree checking (better performance)
|
||
- **no_root_squash**: Allow root access from client
|
||
- **root_squash**: Map root to anonymous user (more secure)
|
||
|
||
## Integration with Calypso
|
||
NFS shares can be used for:
|
||
- Exporting ZFS datasets via NFS
|
||
- Sharing tape library storage
|
||
- Remote backup destinations
|
||
- Distributed storage access
|
||
|
||
## Verification Commands
|
||
\\\ash
|
||
# Check NFS service status
|
||
systemctl status nfs-server
|
||
|
||
# List all NFS-related services
|
||
systemctl list-units | grep nfs
|
||
|
||
# Show active exports
|
||
exportfs -v
|
||
|
||
# Show exports to clients
|
||
showmount -e localhost
|
||
|
||
# Check RPC services
|
||
rpcinfo -p
|
||
