[collectd] rrdcached connecting to an IP instead of unix socket

[Poil]

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
