Hi,
This is probably a FAQ, but I just installed a DRBD package, and it
installed a Xen kernel for/to me. This seems a bit unnecessary, and
arguably unfriendly...
What did it do?
Install a kernel?
Certainly not.
What did I miss?
Here's the RPM info:
$ rpm -q -i drbd
Name : drbd Relocations: (not relocatable)
Version : 8.3.6 Vendor: (none)
You should be using 8.3.7.
We had a package split, 8.3.5 is the last "monolithic" userland,
8.3.6 had minor packaging glitches, and 8.3.7 got the packaging "right".
Previous drbd userland was monolithic,
and to conform to fedora packaging guidelines
we split this into several.
To ease upgrading, the "drbd" package now is a virtual package,
depending ("Requires:") on all parts formerly part of the monolithic
package.
One of those is named drbd-xen, and provides the Xen block device
management script for DRBD.
Again, according to packaging guidelines, this has to
"Requires: xen" (at least on fedora).
This is how it pulls in a lot of xen dependencies,
probably also a kernel ;-)
Which is why we relaxed these Requires for RHEL packages
on the way to 8.3.7.

Summary : DRBD driver for Linux
Description :
DRBD mirrors a block device over the network to another machine.
Think of it as networked raid 1. It is a building block for
setting up high availability (HA) clusters.
This is a virtual package, installing the full DRBD userland suite.
Sic.
Solution: install those packages you actually need,
not "the full DRBD userland suite" (with strict dependencies
according to packaging guidelines).
Thanks for the explanation. Good that you've relaxed your requirements
for future installs. It will also be good when enterprise kernels pick
up DRBD. I'm not sure I'll live that long though ;-).
