MTAB(5)
NAME
mtab − mounted file system table
USAGE
#include <fstab.h>
#include <mtab.h>
DESCRIPTION
The mtab file resides in directory /etc. On DOMAIN systems, it is a link to ‘node_data/etc.mtab, and is created upon installation of DOMAIN/IX software. The file contains a table of devices mounted by the mount(8) command. The mtab file is created at The umount(8) command removes entries.
The table is a series of mtab structures, as defined in <mtab.h>. Each entry contains the null-padded name of the place where the special file is mounted, the null-padded name of the special file, and a type field, one of those defined in <fstab.h>. The special file has all its directories stripped away; that is, everything through the last slash (/) is discarded. The type field indicates whether the file system is mounted read-only or read-write.
This table is present for reference purposes only. It does not matter to mount if there are duplicated entries, nor to umount if a name cannot be found.
