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.
