# mountd(8)

service remote NFS mount requests

## NAME

**mountd** – service remote NFS mount requests

## SYNOPSIS

Obsolete.  See [nfsd(8)](/nfsd/8.md).

## DESCRIPTION

The **mountd** daemon was formerly the server for NFS mount requests from NFS clients. This functionality has been moved into the NFS server daemon [nfsd(8)](/nfsd/8.md).

Please refer to [nfsd(8)](/nfsd/8.md) for NFS server documenation.

The following is a list of former **mountd** options that are now available as [nfsd(8)](/nfsd/8.md) options:

| | | |
| --- | --- | --- |
| **mountd** **option** | **nfsd** **option** | **Description** |
| **-n** | **-N** | allow non-root mounts |
| **-r** | **-R** | allow regular file mounts |
| *exportsfile* | **-F** *exportsfile* | alternate exports file |

However, such configuration options are normally specified via [nfs.conf(5)](/nfs.conf/5.md).

When the NFS server is started, it loads the export host addresses and options into the kernel using the [nfssvc(2)](/nfssvc/2.md) system call.  After changing the list of exports (either directly or indirectly via a change in netgroup membership), the administrator should send a hangup signal to the nfsd daemon to get it to reload the export information:

```
kill -s HUP `cat /var/run/nfsd.pid`
```

For backwards compatibility, the following should also work:

```
kill -s HUP `cat /var/run/mountd.pid`
```

Any errors encountered while processing the export entries will be logged via [syslog(3)](/syslog/3.md).

## FILES

- */etc/exports*

  the list of exported filesystems

- */var/run/mountd.pid*

  the pid of the currently running mountd

- */var/run/mountdtab*

  the current list of outstanding mounts served

- */var/run/mountdexptab*

  information about exported file systems and directories (UUIDs, handles, ...)

## HISTORY

The **mountd** utility first appeared in 4.4BSD. It's functionality was merged into [nfsd(8)](/nfsd/8.md) in Darwin 9.
