Full disk warnings on DICE machines

A small script runs every night on DICE machines. By default it warns if the root partition is more than 95% full. The warning is sent to rootmail - check the rootmail mail folder for messages with a subject like hostname short of space in /. Remember to look for these messages regularly.

How to change it or opt out

You can opt a machine out of the checks by putting this at the top of its LCFG file:

#define INHIBIT_DISK_FULL_WARNINGS
You can add additional partitions to the check like this:
/* Check /disk/scratch too. */
!cron.add_diskfull mADD(/disk/scratch)
Change the percentage fullness value above which a warning message will be sent, in this example from 95% to 73%:
/* Change the full disk warning level */
!cron.add_diskfull mSUBST(95,73)

How to find out more

Look in core/include/full-disk-warning.h or in the diskfull package in the dice subversion repository.
