Why DRBD won’t let you mount the Secondary | Florian's blog
https://fghaas.wordpress.com/2007/06/18/why-drbd-wont-let-you-mount-the-secondary
Linux, High Availability, and other stuff of interest. Why DRBD won’t let you mount the Secondary. As I’m sure you’re aware, DRBD disallows access (any access, including read-only) to a DRBD device in Secondary mode. This always raises questions like the one I’ve taken the liberty to quote here. It came up in a MySQL webinar. On replication and HA:. Because of the asynchronous nature of [MySQL] replication. The short version of this, and related questions, is. Let’s get into this briefly. Volume, an LVM.

“Alternatives” to DRBD | Florian's blog
https://fghaas.wordpress.com/2009/09/16/alternatives-to-drbd
Linux, High Availability, and other stuff of interest. 8220;Alternatives” to DRBD. Every once in a while, people ask us something along the lines of “why do I need DRBD? Can’t I accomplish what it does by other means? 8221; You mean build high availability clusters with block-level synchronous replication? Well, sure you can.
