      That blog post is wrong, it says that DRBD must be active/passive. But it has offered active/active for some time.

      yeah, having tags on the topics makes them better than pinning.

      The article mentions using CentOS, I believe. I'm not able to find the CentOS 7 packages -- they mentioned using the epel-releases, but my system doesn't seem to see it. Any ideas where to look? I'd really rather not have to resort to building it by hand.

      Ubuntu has a PPA for it.

      @whizzard said in The SMB Two Server Dilema, What to Do:

      In scenarios such as these what would be the recommended backup approach: DAS, NAS, Backup Appliance, lower end server, removable disk storage, tapes (intentionally left out cloud)?

      Should be separate (physically!) entity non-related to your production cluster. Cheap NAS is OK.

      For the average scenario (and I really just mean average) it's Synology or ReadyNAS that I recommend. Easy, supported, cost effective, desktop or rackmount options, well known, good brands, nice features.

      When i Restart the drbd service then check the status # cat /proc/drbd
      it shows ( Connected ro:Secondary/Secondary ) , so after doing the below:

      drbdadm disconnect r0
      drbdadm connect r0
      drbdadm primary r0

      and do the same on the other node but # drbdadm secondary r0
      still the same i have no /dev/drbd0

      What is the purpose of 'zypper -remove patterns-openSUSE-minimal_base'
      I know what it does, but is it necessary? Does this minimal_base package prevent you from installing certain packages at a later date? Or you just making things nice n neat?

      It's been quite some time, but if I remember correctly it interfered with some packages that we needed as the "minimal" blocked adding a bunch of stuff.

      @scottalanmiller said in Linux: The Role of DRBD:

      I added a header into the main topic list for that. But it is going to be later in the Advanced Topics, section. Oddly, I know of pretty much no standard Linux Administration tomes that cover DRBD. It's so core, very odd that it so often gets missed.

      Could it be that most Linux Admin's don't know about it until they go searching for it? ...That's how I found out about it.

      You would hope that the people writing the books would know, though!

      As to a two-sever pool, interestingly Ive been working with SC at HA-Lizard over the last few weeks and we've come up with a better way (I think) to support a two-server pool. I've done a lot of torture testing and think there will be a more robust implementation in the near future. I'm particularly interested in that we now have several two-server pools and there is no need to expand just for the sake of supporting HA. Stay tuned for more news on this! For HA to work, you'd still of course need shared pool storage.

      I've never monitored them.

      The work is being done by Dom0, not the VM.

      And with the resources being statically assigned I can't imagine that there is much of a hit to the performance of the VM's them self.

      It's not 100% perfect, but pretty good. Very low risk.
