FreeBSD Unix Show Mounted File Systems
I
recently switched from MS-Windows server to a FreeBSD Unix server. How can I see list of mounted file systems on a FreeBSD based Unix server using command line options?
The command to view mounted files systems, to mount or add any local devices such USB,DVD/CD or remote file systems such asNFS, SAMBA shares or files is the mount command on a FreeBSD operating systems.
How can I list mounted local and remote file systems?
This will list mounted remote and local file systems, run:
$ mount
Sample outputs:
/dev/ada0p2 on / (ufs, local, journaled soft-updates)
devfs on /dev (devfs, local, multilabel)
192.168.1.10:/exports/nas01/data on /mnt/nfs (nfs)
The first field displays the special device such as /dev/ada0p2 or remote file system such as 192.168.1.10:/exports/nas01/data mounted on second field. The second field is the mount point for the file system displayed in the first field. Adding the -v flag will add IDs too:
$ mount -v
Sample outputs:
/dev/ada0p2 on / (ufs, local, journaled soft-updates, writes: sync 3 async 50, reads: sync 1193 async 10, fsid f64cdd52f9f387e7)
devfs on /dev (devfs, local, multilabel, fsid 00ff007171000000)
192.168.1.10:/exports/nas01/data on /mnt/nfs (nfs, fsid 01ff003a3a000000)
If you want to see only a specific file system you would use the -t flag. For example, only show a ufs based mounted file system, enter:
$ mount -t ufs
OR just show a nfs based mounted file system, type:
$ mount -t nfs
Sample outputs:
192.168.1.10:/exports/nas01/data on /mnt/nfs (nfs)
/etc/fstab file
The /etc/fstab contains descriptive information about the various file systems. fstab is only read by programs, and not written; it is the duty of the system administrator to properly create and maintain this file. To see this file, type:
more /etc/fstab
less /etc/fstab
column -t /etc/fstab
Sample outputs:
# Device Mountpoint FStype Options Dump Pass#
/dev/ada0p2 / ufs rw 1 1
/dev/ada0p3 none swap sw 0 0
md42 none swap sw,file=/root/swap1 0 0
More on column -t command
The column command formats its input into multiple columns. It is useful to display mounted file systems in a table format:
mount | column -t
Or try:
( printf Device Mounted On (FileSystem_info)\n ; mount ) | column -t
Sample outputs:
Fig.01: Freebsd Unix mount command and column -t to display output in a table format.
df command examples
The df command shows statistics about the amount of free disk space on a FreeBSD system:
df
Use 1024 byte (1 Kibibyte) blocks rather than the default. ##
df -k
Human-readable outputs ##
df -H
Sample outputs:
Filesystem Size Used Avail Capacity Mounted on
/dev/ada0p2 20G 11G 7.5G 59% /
devfs 1.0k 1.0k 0B 100% /dev
192.168.1.10:/exports/nas01/data 1.6T 297G 1.2T 20% /mnt/nfs
