who is using the space

[Carol Garrett]

I want to search all the way down/through a large filesystem and total up who is using how much space. How to do it ?

[John Palmer]

du -k will give you a list subdirectories and how big they are in kilobytes.

Is this what you require?

[Stefan Farrelly · Accepted solution]

diskusg /dev/vgxx/lvolxx | sort -nbk 3

This will give you a list of all userids and how many blocks they are using throughout the lvol/filesystem. The size is in 512byte blocks so divide by 2 for size in K, eg;

diskusg /dev/vg00/lvol5 | sort -nbk 3

108 tvt1 2945
109 tvt2 100223

user tvt2 is actually using 50Megabytes and tvt1 only 1.5Mb

If all the files are under the users own directories, then just do :-

cd /home
du -sk *

If not, then it's hard work.

You'd need a script to do a find and then add up the info.

or you could turn quota's on to do it for you.

[Patrick Wessel]

May be it's not the most sophisticate way, but a:
du | sort -nr | more

shows you all files sorted by the size

Carol:

Use the quot command. See the man pages. 'quot' gives a good summary by user (account).

...JRF...

[R D SUNDAR RAJAN]

use quot

[Maarten van Maanen]

Please note you can use diskusg and vxdiskusg for accumulating diskspace per user.
Diskusg vor HFS and vsdiskusg vor FXFS-filesystems.

[Mr Amir Mujtabain]

You can use find command with -size n , -atime n and -mtime n option to check larger file creation in specific period and you can also use for du command.

[MANOJ SRIVASTAVA]

Use diskusg ( vxdisusg for vxfs ) file systems .

diskusg ( all the mounted systems ) >> filename

then again use diskusg -s filename | sort +2n -r

this will give the output in descending order . One intresting feature is to use diskusg -s command again on the file as it adds up all the space for same users on different file systems .

Example in the man pages of diskusg does the same.
