[Linux-HA] Heartbeat book

[jan kalcic]

Hi People,

I know there's a lot of documentation out there, but it'd be handy for
me to have a book. Is there one you'd advice me about heartbeat? I found
Linux Enterprise Cluster by Karl Kopper  but I don't actually know if it
is  based on heartbeat.

Regards,
Jan
