Subject Solr over DRBD
Date Mon, 12 Oct 2009 15:38:31 GMT
Hi there,

I have a 2 node cluster running apache and solr over a shared
partition ontop of DRBD.   Think of it like a SAN.

I'm curios as to how I should do load balancing / sharing with Solr in
this setup.  I'm already using DNS round robbin for apache.

My Solr installation is on /cluster/Solr.  I've been starting an
instance of Solr on each server out of the same installation / working
Is this safe?  I haven't noticed any problems so far.

Does this mean they'll share the same index?  Is there a better way to
do this?  Should I perhaps only do commits on one of the servers (and
setup heartbeat to determine which server to run the commit on)?

I'm running Solr 1.3, but I'm not against upgrading if that provides
me with a better way of load balancing.

Kind regards,
