kuedanarrfab: what proc do you need for that?
Arrfabkuedan : read the virtualization guide on http://www.centos.org/docs/5
AgentBlueUK2at this point i should perhaps point out that i'm the co-author of CHRIS Tools which allows you to turn a pair of servers into an iSCSI cluster running on centos http://sourceforge.net/projects/chris
cluster-awareOK...
AgentBlueUK2and the code has huge amount of paranoia to ensure that everything is as it should be and your not cutting any corners
cluster-awareThen wait for 5, and advise your downstream to do so as well
I don't see any documentation up on the sf.net link
You're using replication?
AgentBlueUK2the docs are there, they are in SVN (i think)
cluster-awareI'll have to check that out
Why replication?
AgentBlueUK2this year has been a little manic so not had chance to finish putting together the SF project page properly
cluster-awareRather than a shared filesystem?
AgentBlueUK2http://chris.svn.sourceforge.net/viewvc/chris/trunk/docs/source/
cluster-awareIf you're going to use clustering, use GFS too... that's the only part of the free cluster tools that doesn't sux0r.
AgentBlueUK2given how cheep storage is now, if your going to put all the companies eggs on one basket, i'd rather than basket had full N2 redundancy
cluster-awareOther than replication is not perfect itself
AgentBlueUK2what's wrong with DRDB ?
cluster-awareand replication can still happen to another site, for storage hot backup
actionArrfab looks at the /topic ...
Arrfablooks at the /topic ...
cluster-awareI don't trust replication - I've seen it fail too manu times
/manu/many/
AgentBlueUK2drdb can't (unless split brain)
cluster-awareYou can replicate at the storage layer for redundancy, but for a/a, I'd personally stick with shared storage
AgentBlueUK2see my PMs
EvolutionArrfab: RIP topic.... long live topic.
ArrfabEvolution : hmmm, it seems so ... but wait for orc to appear and change the topic again ... :-P
kingbowhere is centos5
indigoblucluster-aware, so you dont like live replication of database? (ie: shipping transaction logs)
radovoipleave it to my kids to screw up my stuff
AgentBlueUK2not out yet ;-)
BlackHanddb replication ? mysql ? postgresql ?
indigobluBlackHand, I believe postgresql
cluster-awareindigoblu, I was speaking of active/active use with filesystem replication
indigoblucluster-aware, what fs does that best?
cluster-awareShipping trasaction logs is a great idea in an a/p setup
It depends on what features you're looking for
As AgentBlueUK2 has pointed out, drdb does this at the block / filesystem level
BlackHandcluster-aware: active-active database ?
cluster-awareIs your database cluster-aware?
