Hi,
I've been fighting with the OCF DRBD script returning me success when trying
to get a resource secondary, when it failed : the drbdadm secondary command
fails (returns 11) and the drbd script returns 0. It's with heartbeat 2.1.4.
I think I've located the culprit :
do_drbdadm() {
local cmd="$DRBDADM -c $DRBDCONF $*"
ocf_log debug "$RESOURCE: Calling $cmd"
local cmd_out=$($cmd 2>&1)
ret=$?
# Trim the garbage drbdadm likes to print when using the node
# override feature:
local cmd_ret=$(echo $cmd_out | sed -e 's/found __DRBD_NODE__.*<<//;')
if [ $ret -ne 0 ]; then
ocf_log err "$RESOURCE: Called $cmd"
ocf_log err "$RESOURCE: Exit code $ret"
ocf_log err "$RESOURCE: Command output: $cmd_ret"
else
ocf_log debug "$RESOURCE: Exit code $ret"
ocf_log debug "$RESOURCE: Command output: $cmd_ret"
fi
echo $cmd_ret
return $ret
}
local cmd_out=$($cmd 2>&1)
ret=$?
In this case $? always is 0. As I don't know sh that much (and hate it a
lot :) ), I've been trying to find the reason, and as soon as I remove
the 'local', the return code is transmitted to $? again.
This is quite an important problem I think, because whenever heartbeat fails
to do a drbd command, it thinks it has worked (instead of retrying).
