Boasting now as the fresh BSD Magazine puts my paper “Nearly Online Zpool Switching Between Two FreeBSD Machines” on top of the issue’s cover. My text is about problems of ZFS storage pool sharing between computers and solutions of overcoming these obstacles.
To read the paper, download the issue from BSD Magazine site, or see the author’s version of the article on my blog: “Approaching online zpool switching between two FreeBSD machines“.
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.
Many thanks to Ewa and the BSD Magazine team for their perfect work!
