[Xen-users] Re: Xen nexentastor-3.0.2-xen.cfg (blktap)
Apply two patches attached to current
http://xenbits.xensource.com/xen-4.0-testing.hg
( r4 is good as well)
1. First patch per Mark Johnson
2. Second patch per exeCooler.
Currently i run NexentaStore Xen instance under Xen 4.0.1-rc4 ( 2.6.32.16) on
top of F13, but Debian as a base shouldn''t make much difference ( udev
<= 151).
But , Nexenta is 64-bit.
Boris.

Hi!
Sorry that I maybe disturb you,
I have the problem to get nexenta running with xen and read many things that you
posted.
So I think you have the most experience with this.
I tried to apply the patches you talked about:
http://www.gossamer-threads.com/lists/xen/devel/178392
http://bderzhavets.wordpress.com/2010/07/11/execoolers-patch-for-xen-4-1-unstable/
Do you know of a working setup for getting xen + nexenta running under Debian?
I want to use nexenta (32bit because cadp) + adaptec (passthrough) + HP LTO2
448 (ndmp in nexenta)
with xen because nexenta on it''s own doesn''t like my two
SATA-Controllers,
even if it shows my disks when using iostat, I can''t get the disks to
work.
Thx in advance.
And tried to edit the nexenta-xen-cfg multiple times like:
disk = [
''tap2:tapdisk:vhd:'' + work_dir + ''/''
+ disk_1_name + '',xvda,w'',
...
]
debian:/opt/vm/nexenta# xm create -c nexentastor-community-3.0.2-xen.cfg
Using config file "./nexentastor-community-3.0.2-xen.cfg".
Error: Boot loader didn''t return any data!
or:
''tap:tapdisk:vhd:'' + work_dir + ''/'' +
disk_1_name + '',xvda,w'',
debian:/opt/vm/nexenta# xm create -c nexentastor-community-3.0.2-xen.cfg
Using config file "./nexentastor-community-3.0.2-xen.cfg".
Error: Device /dev/xvdp (51952, tap) is already connected.
