Hi to everyone !
I''m new here, so this is my first post.
I''m playing around with Xen Server on an Ubuntu server installation
using LVM as its main disk management framework. Well it''s an
installation option to do so ... (maybe that wasn''t a good idea to
choose in the first place...)
Now...
Of course I came to the point where I needed an SR. Following some tutorials I
created a new partition, in my case an LV, and an SR on top of it.
When I checked the LVM settings I saw that a new PV, VG and LV have been
created.
So I thought "WOW" ... next I did was checking the data rate, so I
wrote a file with 4G in size (with dd) to the disk. One to the disk created for
the SR and one to a disk one "abstraction layer" lower (or obove ? ...
whatever ... :) ).
The difference was quite noticable ~175MB/s on the SR disk and ~211MB/s one
layer lower...
Hm... I did some searching, but this seems to be the normal way...
So my question: Is it somehow possible to attach an LV to be used (and managed)
by XEN as a SR more directly (instead of having it create this whole bunch of
virtulization-thingies...)
Because I didn''t find anything in the web this might be a stupid
question but I thought ... well ... ask anyway :)
Greetings,
Oliver
