My quota on openshift has exceeded:
Filesystem blocks quota limit grace files quota limit grace
/dev/mapper/EBSStore01-user_home01
1048572 0 1048576 6890 0 80000
I found a different stackoverflow questions that the disk space can be cleaned by 'rhc app-tidy'
But when i run this command i get the following error:
Warning: Gear xxx is using 100.0% of disk quota
Failed to execute: 'control start' for /var/lib/openshift/xxx/mysql
When i run the following command do see which files are using the most space
du -h * | sort -rh | head -50
I get the following ouput:

As you can see the git directory takes a lot of space, but when i try to do 'git gc', i get the following error:
Counting objects: 226, done.
Delta compression using up to 2 threads.
Compressing objects: 100% (192/192), done.
dm-0: write failed, user block limit reached.
fatal: sha1 file '/var/lib/openshift/xxx/git/mythings.git/objects/pack/tmp_pack_ipHspL' write error: Disk quota exceeded
error: failed to run repack
So now i am out of ideas, what can i do to cleanup some space?
Thanks!
Delete whatever you can easily restore from a backup or from a package, like e.g. the JDK. That should give you enough space to do cleanup. Then restore whatever you deleted.
Or pay for more storage. :-)
As mentioned above you need to ssh to your cartridge (you will find code in web console - next to delete button) and then cd to app-root/logs and then run du -sh to check the dimension of the current dir, in my case the the file php-error.log was 542M. You can safe delete it with rm -f php-error.log
ssh to the application directory using ssh clients (i use putty) or command prompt then
try to find out unnecessary files and delete them.
In my case deleting the content of app-log folder worked like charm.
Give attention to temp and log folders
