Right - if you use CTDB, then you need a cluster FS.
But, does CTDB really helps you?
With the hardware you described I really doubt that you get more performance using CTDB compared to a single access samba server.
If you have high speed disks, high speed network connections, then CTDB provides more performance. If one of this is missing you will miss the performance.
In addition, you're using DRBD, which is different from accessing a shared - and fast - storage.
If you do not gain performance by using CTDB then it only increases the complexity of the setup - worst case is that you loose performance.
That said, you might get a better experience using traditional samba in a fail-over configuration.
Hi Kai Thanks for the input. It's not performance we want. We're never going to get that. It's reliability. What do you mean by fail over? I think we already have that. If one node fails, there is always the other one already up. If you mean have only one node available at a time, what's the advantage of that? Also, how are we going to serve a windows domain without ctdb? L x -- To unsubscribe, e-mail: opensuse-ha+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-ha+owner@opensuse.org
