This even does the grepping in parallel, so if syslogs is bigger than your disk cache this will go considerably faster than reading the file from disk over and over again. The option -j0 may be useful to you as well.

hb_takeover
HB_TAKEOVER(1) General commands HB_TAKEOVER(1)NAME
hb_takeover - issues a failover request to the cluster manager
SYNOPSIS
hb_takeover [all|foreign|local|failback]
DESCRIPTION
Warning
This command is deprecated. It is only suitable for legacy Heartbeat clusters without Pacemaker enabled. In Pacemaker-enabled clusters,
the crm(8) shell supports switching individual nodes into standby mode, and replaces hb_takeover.
/usr/share/heartbeat/hb_takeover issues a request to the cluster to move resources to the node where it is invoked, from the other node.
Issuing hb_takeover on the current node is equivalent to performing hb_standby on the other node.
CAVEATS
hb_takeover is only usable in R1-style configurations (i.e., those configured using the haresources file).
