[DRBD-user] Using DRBD above a mirror softraid (RAID1) with XEN 5.61

[John-Patrice Weigner]

Dear community,

I'm new to DRBD and configured my first test-machine with DRBD and Xen 
Server 5.61 yesterday.
Now I'm curious if it is possible to use DRBD as listed above.

  The DRBD User Guide doesn't tell much about it, so I hope somebody 
could explain me how to set up a RAID 1 under Citrix XEN 5.61. Let's say 
I do have a LSI-Logic onboard SAS-RAID-controller shipped with my server.

Should I use the FakeRaid-Controller or better build a RAID1 with mdadm 
under XEN Server (CentOS) itself? Are there any gotchas?

I read about some performance issues concerning RAID1 and DRBD. Is they 
any solution with my version drbd-utils-8.3.10-1.i386.rpm?

Thanks in advance and kind regards,

John
