Defaults are set to provide compatibility with earlier releases. An upgrade shouldn't change the configuration files meanings. So, when a new feature is added, where it didn't exist before, the default should be OFF. If you want to use the new feature, then you turn it on manually, and verify that it didn't break anything. There is enough "drama" at new release time that you don't need to make more changes than necessary. After the upgrade has settled in, then you turn on the new features and make sure they do what you want.
So, in your case (new install), turn on all the new stuff! As to the I/O handling with DEBD+GFS2+NFS Primary/Primary, I do not know the answer. Maybe someone else on the list can help.

I've been reading manuals hard but still have lots of questions. 1) Configuring I/O error handling strategies I see detach method is highly recommended but pass_on is still default method. Why? What differences between these methods? Why we have unrecommended method as default instead of the first one? I have DEBD+GFS2+NFS Primary/Primary solution. What should I use in my case? Why? 2) I see configuring checksum-based synchronization and replication traffic integrity checking are not enabled for resources by default and I don't have them also. I don't like it and I wont to turn them on, but I have thought "m.b. they haven't been enabled knowingly". So my question is why them haven't been enabled and what I will have if I turn it on? Lost my performance? Stability? Thank you in advice, Ivan. _______________________________________________ drbd-user mailing list [email protected] http://lists.linbit.com/mailman/listinfo/drbd-user
