I'm not sure if I've understand what you are doing but
I think with heartbeat you can manage start/stop of rrdcached with a
different configuration for your rrdcached srv1 and rrdcached srv2 and
simply listen on the true IP

I'm using a virtual IP for the rrdcache daemon. The virtual ip floats
between my two collectd hosts. I'm trying to get this to work without
the unix sock because I want the data to be sent only to the virtual
IP which will shift between the servers. The virtual ip will shift
between the two servers as will the mount point that the data is
written to. My rrdcached config looks like this.
/etc/sysconfig/rrdcached
OPTIONS="-P
FLUSH,FLUSHALL,PENDING,FORGET,QUEUE,HELP,STATS,UPDATE,WROTE,BATCH,QUIT
--l virtualip:42217 -F -s root -m 664 -b /data/collectd/rrd -j /tmp/
-w 300 -z 90 -t 20

unix socket
Hi,
I'm not a work but I think i'm using this configuration for rrdcached
daemon
rrdcached -f 7200 -w 3600 -z 900 -b////opt/collectd/var/lib/collectd/rrd// -P
FLUSH,BATCH,UPDATE,STATS -l 127.0.0.1 -l unix:/tmp/rrdcached.sock
Why don't you use a virtual IP on top of your "drbd servers" IPs?
There was a small bug on rrdcached collectd plugin, umask wasn't correct, search for " [collectd] rrdc_update failed with status -1" in this mailing list
Best regards

Hey quick question is it possible for rrdcached to connect to an
IP address instead of a unix socket with the rrdcached plugin.
The following is my rrdcached config and collectd config working
with the unix socket
-----------------------------------------------------------------------------------------
/etc/sysconfig/rrdcached
OPTIONS="-l unix:/var/rrdtool/rrdcached/rrdcached.sock -F -s root
-m 664 -b /data/collectd/rrd -j /tmp/ -P FLUSH,PENDING -w 300 -z
90 -t 20"
/etc/collectd.conf
LoadPlugin rrdcached
<Plugin "rrdcached">
DaemonAddress "unix:/var/rrdtool/rrdcached/rrdcached.sock"
DataDir "/data/collectd/rrd"
CreateFiles true
</Plugin>
-------------------------------------------------------------------------------------------
The following is not working if I'm running rrdcached bound to an
IP instead of a unix socket.
/etc/sysconfig/rrdcached
OPTIONS="-P
FLUSH,FLUSHALL,PENDING,FORGET,QUEUE,HELP,STATS,UPDATE,WROTE,BATCH,QUIT
-l hostname:42217 -F -s root -m 664 -b /data/collectd/rrd -j
/tmp/ -w 300 -z 90 -t 20
/etc/collectd.conf
LoadPlugin rrdcached
<Plugin "rrdcached">
DaemonAddress "hostname:42217"
DataDir "/data/collectd/rrd"
CreateFiles true
</Plugin>
Changing any of the --P options dosen't seem to help.
I know the recommend method is to use the unix socket, however I'm
going to be running this in drbd setup so basically the directory
where the files and daemon are running on can change. I have a
floating IP that will move between the collection servers. That's
why I need to be able to set the DamonAddress to an IP. The IP
for the Daemon Address will be able to write to the directory
correctly.
Any help would be appreciated.
