Uhhh.... quotas?
Uhhh.... at least using a cat /proc/whatever instead of df?
Here's the code from /etc/multicron-p:
periodic () {
checkfreespace
pingcheck
}
...
updatefree () {
IFS="$SP$TAB%"
set -- $(df | sed -n 2p)
IFS=$OIFS
bfree=$4
pfree=$((100 - $5))
}
ckfree () {
[ $bfree -le ${lrp_SC_MINKB:--1} ] && return 1
[ $pfree -le ${lrp_SC_MINPER:-101} ] && return 1
return 0
}
the annoying thing is that I don't see where it's getting called from --
it's not in crontab, but I do know it's getting called because the ping
check goes off about hourly.
