This article introduces the relevant knowledge of "what are the methods for linux to view disk mounting". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

The first method: use the df command, for example:

The code is as follows:

Orientalson:/home # df

Filesystem 1K-blocks Used Available Use% Mounted on

/ dev/sda2 15213032 8043668 7169364 53%

Udev 514496 104 514392 / dev

/ dev/mapper/vg_test-lv_test

511980 32840 479140 7% / home/mt

Orientalson:/home #

The mount point / home/mt shown above is not on the same line as the volume she mounted, so it is troublesome to use shell script analysis.

The second method: use the mount command, mount-l, which has the disadvantage of not having the size of the volume, but the mount point is on the same line as the mounted volume. For example:

The code is as follows:

Orientalson:/home # mount-l

/ dev/sda2 on / type reiserfs (rw,acl,user_xattr) []

Proc on / proc type proc (rw)

Sysfs on / sys type sysfs (rw)

Debugfs on / sys/kernel/debug type debugfs (rw)

Udev on / dev type tmpfs (rw)

Devpts on / dev/pts type devpts (rw,mode=0620,gid=5)

Securityfs on / sys/kernel/security type securityfs (rw)

/ dev/mapper/vg_test-lv_test on / home/mt type reiserfs (rw) []

Orientalson:/home #

The third way: look at the file / etc/mtab. The principle is that each newly mounted volume will basically update the file, so you can naturally view the mount point and mount volume through this file. This approach is a little clearer than mount-l, but it is sometimes unreliable.

The code is as follows:

Orientalson:/home # cat / etc/mtab

/ dev/sda2 / reiserfs rw,acl,user_xattr 0 0

Proc / proc proc rw 0 0

Sysfs / sys sysfs rw 0 0

Debugfs / sys/kernel/debug debugfs rw 0 0

Udev / dev tmpfs rw 0 0

Devpts / dev/pts devpts rw,mode=0620,gid=5 0 0

Securityfs / sys/kernel/security securityfs rw 0 0

/ dev/mapper/vg_test-lv_test / home/mt reiserfs rw 0 0

Orientalson:/home #

It has been said above that this file will basically be updated, but this issue is not always updated. If the-n option is used when mounting, then the new volume information will not be mounted in the / etc/mtab file.

The code is as follows:

Orientalson:/home # umount / home/mt

Orientalson:/home # mount-n / dev/vg_test/lv_test / home/mt

Orientalson:/home # cat / etc/mtab

/ dev/sda2 / reiserfs rw,acl,user_xattr 0 0

Proc / proc proc rw 0 0

Sysfs / sys sysfs rw 0 0

Debugfs / sys/kernel/debug debugfs rw 0 0

Udev / dev tmpfs rw 0 0

Devpts / dev/pts devpts rw,mode=0620,gid=5 0 0

Securityfs / sys/kernel/security securityfs rw 0 0

Orientalson:/home #
