FWIW, Just stay patient, LINBIT is working hard on developing next generation features for DRBD that address scalability, and versatility in your replication. Sure, glusterfs and ceph are cool and fit a number of use cases...but "cool" and "shiny" doesn't save you from disaster and headache when you need safe and reliable replication. This is where DRBD really exceeds expectations :) Arnold, Thanks for chiming in and sharing your personal real world experiences, as these are important to contrast when looking for the right solution. In short, we're working on improving DRBD's feature set substantially, and with the support of the community (feedback, bug fixes, and open communication) we know that DRBD has some very cool new capabilities on the horizon. > A sidenote to get back on topic: While my co-admin had his small victory some > months ago, when it was decided to go back from drbd-hosting to his extra- > iscsi machine, last week that machine had a problem starting after an power- > outage.

We're fine with being a few features behind as long as folks don't lose data. :) Just to put this out there for anyone who's reading this if you are using DRBD and want it to do more. Contact us and tell us what you want DRBD to do!
