Full disk warnings on DICE machines
A small script runs every four hours 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
