Description Thomas Wiest 2013-06-02 15:20:36 UTC

Description of problem:
When a gear's user account is created, the system creates a file in /var/spool/mail/ for their mail.

However, when a gear is removed, that file is left around.

The list of files in that directory just keep growing as more gears are created and removed.

This also starts to exhaust the number of inodes of the FS (that's how we found this).

In addition to fixing this bug, please also add a check to oo-accept-node that ensures that there aren't any gear files left in /var/spool/mail for removed gears.

This is to ensure this doesn't happen again in the future and also that all of the past gear files have been cleaned up.


Version-Release number of selected component (if applicable):
rhc-node-1.8.7-1.el6oso.x86_64


How reproducible:
very


Steps to Reproduce:
1. Create a gear
2. Remove that gear
3. Notice that that gear left around a file in /var/spool/mail/


Actual results:
leaves around a file when a gear is removed


Expected results:
file should be removed as well

Checked on devenv_3321, issue has been fixed.

After gear removed, /var/spool/mail/<gear_uuid> will be removed accordingly.
