User mezzantrop gives us an update on his FreeBSD dual-controller storage system dubbed BeaST. He has updated the project page and BeaST paper, as well as posted another article about zpool switching. Read the full updates at the links provided.
We all know that ZFS pool is designed to be used by a single machine only at any particular point of time, and when we want to access a zpool from another system we have to export it and import to the new server. This disadvantage makes simultaneous direct usage of the pool quite impossible for reliable dual-controllered storage systems.
