# Troubleshooting NFS Errors

> For the full documentation index, see: https://docs.mulesoft.com/llms.txt

> [!IMPORTANT] Setting up and configuring an NFS server should be performed by your infrastructure
> team. If you experience problems with any of the following instructions, contact your
> infrastructure team for assistance.

> [!NOTE] This page applies only when installing Anypoint Platform PCE in NFS mode. If you are using
> StorageClass mode (Anypoint Platform PCE 4.3.0 and later), troubleshoot storage issues through
> your `StorageClass` provider and CSI driver instead. See
> [StorageClass Mode](https://docs.mulesoft.com/private-cloud/latest/verify-nfs#storage-class-mode).

You must have a connection from each node to NFS.

## “Server Not Responding”

Use a tool such as ping, traceroute, or tracepath to verify that the client and server machines can
communicate with each other. If communication fails between the client and server machines, examine
the network interface card (NIC) settings using either `ifconfig` or `ethtool` to verify the IP
settings.

## “Access Denied” or "Permission Denied"

Check the export permissions for the NFS file system. You can do this from the client or from the
server.

From the client:

`showmount -e server_name`

From the server:

`exportfs -a`

## "rpc mount export: RPC: Timed out"

The error message `Unable to access file system at [NFS SERVER]: rpc mount export: RPC: Timed out`
is caused by a DNS name resolution issue. NFS (RPC) needs reverse name resolution. If the NFS server
or client cannot resolve their name, this error occurs. Check the DNS configuration and the
`/etc/hosts` configuration.

## Mounting the NFS Server Fails

If the mount fails, you are probably missing some NFS-required libraries. If this happens, install
them by running:  
`yum install nfs-utils nfs-utils-lib`

### "mount failed: Not Permitted"

The error message `mount failed: exit status 32. Mounting command …​ not permitted` might occur when
trying to mount using the `noresvport` option because the ports might be limited. If this happens,
remove the `noresvport` option and add the `insecure` flag to the mount command.
