If you are running into disk space issues, there are a number of things you can do before adding storage or moving to a larger gear size.
As a reminder, Free Plan Small gears are restricted to 1GB of storage. The Bronze Plan allows you to purchase additional storage at $1/GB per month, and the Silver Plan includes 6GB of storage for every gear.
The additional 5GB for the Silver Plan is not assigned automatically, but you can do it using the following command:
$ rhc cartridge-storage <cart_name> -a <app_name> --set 5
You can also do that using the web interface:
Click your app name → click the 1GB link under the Storage label → select 5 GB from the drop-down list → Save.
If you are on the Free Plan, the first step is to see what directories and files are taking up the most space.
To do this, first ssh into your gear:
> du -h * | sort -rh | head -50
This will give you the 50 largest directories and files on the gear.
There is a simple command that will clean up the application’s logs, tmp directories, and even tidy up the git repo on the server:
$ rhc app-tidy <app_name>
If you want to erase your entire history from a Git repository and start over with your current files as the initial commit, see this forum post.
Monitoring Inode Consumption
There is also an inode quota for each gear - 40,000 inodes per GB of storage. To put it simply, inodes are assigned to every filesystem object and they contain metadata for the object it’s assigned to. Since everything must have an inode assigned to it, each file/folder within your app will consume 1 inode.
To view your inode consumption:
First ssh into your gear:
Then run the
quota -s command:
> quota -s
Disk quotas for user ********************* (uid *****):
Filesystem blocks quota limit grace files quota limit grace
/dev/mapper/EBSStore01-user_home01 601M 0 1024M 3447 0 80000
The example output above shows that this app is consuming 3,447 inodes of the 80,000 limit.
Currently the only way to reduce inode consumption is to keep the amount of files within your app to a minimum.
