All,

I just received a notification that my /usr directory is 85% full. It has allocated space of 1.8G and is using 1.5G.

This is what I get when I run a DF:

Filesystem Size Used Avail Use% Mounted on
/dev/mapper/system-usr
1.8G 1.5G 276M 85% /usr


This is what I get when I run an ls -l inside the /usr directory:

total 73

So it appears that the directory hasn't been touched since January.
Is it possible that this /usr directory can grow without being tagged with a "last touched" date?...

It seems odd that the /usr directory has grown to 1.5GB and I am just receiving a notification of it now....

Any ideas?

Thanks,
Mathew

The timestamp reflects when the contents of a folder were modified. If a file is modified inside of it, this will not change the folder's timestamp.

Try running the following in the /usr directory:

du -kx |sort -nr |head

This will show you the largest offenders for size in /usr.

Thanks slack.
This is the result of what you suggested. What is the '.' representing? The top level directory '/usr'?
Do /usr directories normally swell up?


usbcsap82:/usr # du -kx |sort -nr |head
1557367 .

. is the total size of /usr

It's hard to say, because you have not told us how big /usr was before. It is possible that an increase of just a few mb triggered the warning. My /usr is using 2.2GB. If you want to continue examining this issue, search for the most recently modified files in /usr. Otherwise, it's simpler to just continue monitoring disk usage over a few weeks/months.

Many thanks for everyones response. I will monitor the growth of this directory over the next few months. Thanks for all your input.
