Hi > We have just published an initial public draft of the all-new DRBD Users' > Guide which will henceforth be available at http://www.drbd.org/users-guide/. Very nice work. Thank you very much. > This guide is going to be in "public draft" status all through the month of > March. We request, strongly encourage and much appreciate feedback. > Corrections are more than welcome, as are suggestions for improvement. I skipped the LVM, cluster FS and DRBD Internal parts. Here are some suggestions for the rest of the document. http://www.drbd.org/users-guide/ch-admin.html Inconsistent. The data are inconsistent s/are/is http://www.drbd.org/users-guide/s-enable-dual-primary.html IIRC, become-primary-on-both; was introduces in a recent version. If so, one could think of adding the version number as you did in several other places. http://www.drbd.org/users-guide/s-resizing.html "ensure that only one node is in primary state" Is this to say that it works in a primary/primary configuration, but only if you temporarily put one node to secondary mode? That could be made clearer. "are shrunk first" the "first" should be highlighted imho :) list point 7: I think theres a \n missing after "/tmp/metadata" http://www.drbd.org/users-guide/s-resolve-split-brain.html "At this point, you must manually intervene" A link might refer to the section about automatic split-brain recovery. http://www.drbd.org/users-guide/ch-heartbeat.html "they are be started and stopped by the cluster manager" s/be// or maybe you meant "are to be"? http://www.drbd.org/users-guide/ch-heartbeat.html R1 can only deal with heartbeat and LSB Resources. OCF Resources are for R2 only. You even say so: http://www.drbd.org/users-guide/s-xen-heartbeat.html Although - there is a wrapper for R1 that makes it possible to use OCF RAs in R1, but I don't know how to use it and wether that should be stated in this place. http://www.drbd.org/users-guide/s-heartbeat-r1.html "Resource group support is limited to two resource groups" Thats not true. You can have more than two resource groups. It's just that more than 2 groups are internally treated as one large group per node. http://www.drbd.org/users-guide/s-heartbeat-dopd.html This does not mention the difference in configurations with stonith enabled. You might at least place a link to the blog here. http://www.drbd.org/users-guide/s-xen-internal.html Although it *should* be clear, you could state that one needs to copy block-drbd to /etc/xen/scripts Or is block-drbd a part of xen by now? http://www.drbd.org/users-guide/s-xen-heartbeat.html As you earlier described R1 first, you might want to keep doing this.
