Hi folks, I'm looking at making a scalable zope infrastructure, I can
scale the ZEO clients and mysql, the only issue is the ZEO server. I
have used drbd and heartbeat in the past to create a HA lamp stack. From
a technical standpoint, is there any reason I could not use drbd to
cluster the ZEO server? Any thoughts would be appreciated.
As far as I understand, the difference to ZRS (which is a solution to
scale ZEO servers, e.g. for HA) that you will need to restart the ZEO
server when switching a hot-spare ZEO server to "live-mode", because it
doesn't notice when the underlying storage file is changed by somebody else.
