[DRBD-user] notify-split-brain.sh[153967]: Environment variable $DRBD_PEER not found (this is normally passed in by drbdadm).

[Daniel Ragle]

Anybody know where I need to start looking to figure this one out:

notify-split-brain.sh[153967]: Environment variable $DRBD_PEER not found 
(this is normally passed in by drbdadm).

I have a split-brain situation and apparently this notification script 
tried to run but failed.

This is in a pacemaker setup with ocf:linbit:drbd controlling DRBD.
