Remove Unused NFS
To remove or delete an unused NFS export entry that you no longer need, you can follow these steps:
Identify the Export Entry
First, identify the export entry you want to remove by running exportfs -v
with sudo
:
sudo exportfs -v
This command will list all the NFS exports currently configured on your system.
Remove the Export Entry
To remove an NFS export entry, you use the exportfs
command with the -u
option followed by the path of the export. Here’s the general syntax:
sudo exportfs -u [options] export_path
- Replace
export_path
with the path you want to remove from the NFS exports. -
-u
option is used to unexport (remove) the specified export path.
For example, if you see an export like /mnt/nfs_share *(rw,fsid=0,sync,no_subtree_check)
that you want to remove, you would use:
sudo exportfs -u /mnt/nfs_share
Restart NFS Service
Restart NFS Service: After removing the export entry, restart the NFS server to apply changes:
sudo systemctl restart nfs-server
Verify Removal
After running the exportfs -u
command, you can verify that the export entry has been removed by running exportfs -v
again:
sudo exportfs -v
The entry you removed should no longer appear in the list of NFS exports.
Additional Notes
- Make sure to review the list of NFS exports carefully before removing any entry to avoid unintentionally deleting important configurations.
- Changes made with
exportfs
are immediate and affect NFS clients accessing the exports. Ensure any necessary changes are communicated if NFS exports are actively used.
By following these steps, you can effectively remove an unused NFS export entry from your system using exportfs
on Ubuntu or any Linux distribution that supports NFS.
