Installs and configures the Distributed Replicated Block Device (DRBD) service for mirroring block devices between a pair of hosts. Right now it simply works in pairs, multiple hosts could be supported with a few small changes.
drbd cookbook does not partition drives. It will format partitions given a filesystem type, but it does not explicitly depend on the
xfs cookbook if you want that type of filesystem, but you can put it in your run list and set the node['drbd']['fs_type'] to 'xfs' or 'ext4' or whatever.
Tested with Ubuntu 10.04 and 10.10. You must have the 'linux-server' package and 'linux-headers-server' kernel installed to properly support the drbd module.
Installs drbd but does no configuration.
Given a filesystem and a partner host, configures block replication between the hosts. The master will claim the primary, format the filesystem and mount the partition. The slave will simply mirror without mounting. It currently takes 2 chef-client runs to ensure the pair is synced properly.
The required attributes are
node['drbd]['remote_host']- Remote host to pair with.
node['drbd]['disk']- Disk partition to mirror.
node['drbd]['mount']- Mount point to mirror.
node['drbd]['fs_type']- Disk format for the mirrored disk, defaults to
node['drbd]['master']- Whether this node is master between the pair, defaults to
There are a pair of example roles
drbd-pair-master.rb with the cookbook source.
