Description

This article provides information on how to display the size of a specific directory or sub-directory.

Symptoms

If the size of a particular directory is required, whether for a upgrade or to keep track of the directory size , the default show system storage command will not determine the capacity or the used space of a particular directory.


Solution


For example, show system storage will not display the specific size of a /var/tmp directory:

lab> show system storage
Filesystem Size Used Avail Capacity Mounted on
/dev/da1s1a 885M 180M 697M 20% /
devfs 1.0K 1.0K 0B 100% /dev
/dev/md0 49M 49M 0B 100% /packages/mnt/jbase
/dev/md1 315M 315M 0B 100% /packages/mnt/jkernel-ppc-11.4R1.14
/dev/md2 19M 19M 0B 100% /packages/mnt/jpfe-MX80-11.4R1.14
/dev/md3 5.3M 5.3M 0B 100% /packages/mnt/jdocs-11.4R1.14
/dev/md4 95M 95M 0B 100% /packages/mnt/jroute-ppc-11.4R1.14
/dev/md5 24M 24M 0B 100% /packages/mnt/jcrypto-ppc-11.4R1.14
/dev/md6 2.8G 10.0K 2.6G 0% /tmp
/dev/md7 2.8G 1.2M 2.6G 0% /mfs
/dev/da1s1e 99M 258K 97M 0% /config
procfs 4.0K 4.0K 0B 100% /proc
/dev/da1s1f 2.8G 2.5G 108M 96% /var


To find the specific size of any directory, as in the above example of /var/tmp ,  perform the following procedure:

-----------------------------
lab> start shell
% du -hs /var/tmp
424M /var/tmp
-------------------------------

424M is the used space. This can also be verified with the /var directory via show system storage :
root@% du -hs /var
2.5G /var
To clean the device space, you can try remove the unused file via the CLI:
> file delete xxx

or use the following CLI command to clean up the temporary files:
{MASTER}
lab@T1600-re0> request system storage cleanup
