High Availability Clustering and Heartbreak.

Recently a couple of Linode VMs were acquired by my employer. It was decided that these would host OpenVPN, OpenLDAP, PostgreSQL and a couple more services in a HA cluster. This seemed like a great idea, and much congratulating occurred.

Little did we know what awaited us.

That seems a bit unfair to LVM. Using an existing layer of functionality isn't that outre really. *g* Plus :: snapshots!!

Fuck rsync backups. Fuck 'em in the bad place.

I won't deny that LVM is quite useful, but it wasn't something we needed to mess with. Straight DRBD and OCFS2 work pefectly for our purposes. Backups of data will go to Amazon's S3 via Amanda Backup, more than likely.
