mmdu
Disk usage for IBM Spectrum Scale (formerly GPFS) file systems.
-
uses
mmapplypolicy
instead of universal directory traversalThis can be considerably faster, especially for large directories, because it uses file system internals and can use extensive parallelism. See the respective command-line options in
--help
output for more information. -
aims to be CLI compatible with
du
from coreutilsNot all options of
du
are supported yet. Some defaults are still different.
Run with -?
for concise help and --help
for full help.
Motivation and Usage
The main motivation is a speedy alternative to du
due to mmapplypolicy
being much faster then universal directory traversal.
But because mmapplypolicy
can not be run as a regular user, it is advisable
to set up timer or cron jobs to run this as a service for users and groups. You
could set up timers that run mmdu --max-depth x
for each /data/dir
and save
the output to /data/dir/disk-usage.txt
. Users could configure the depth and
then check the output with sort -h /data/dir/disk-usage.txt
. This avoids that
users have to do their own slow-running du -sh
and avoids that stress to the
file systems.
