[Xen-users] Can Xen deal with minors greater than 255?

[David Muench <davemuench@xxxxxxxxx>]

I've been reworking my Xen setup again, and am having problems adding
an AOE (ata over ethernet) device to a domU. If I assign the
/dev/etherd/e1.0p1 directly to the domU, I get this error:

root@sol:/dom/luna# xm create luna.conf -c
Using config file "luna.conf".
Error: Adding extent to vbd failed: device (vbd (uname
phy:etherd/e1.0p1) (dev sda1) (mode w)), error 8
root@sol:/dom/luna#

Here is the disk line from my luna.conf:

disk = ['phy:etherd/e1.0p1,sda1,w', 'phy:etherd/e1.0p2,sdb1,w']

I noticed my e1.0 devices have a minor greater than 255:

brw-rw----  1 root disk 152,  256 Feb  3 08:04 e1.0
brw-rw----  1 root disk 152,  257 Feb  3 10:21 e1.0p1
brw-rw----  1 root disk 152,  258 Feb  3 10:21 e1.0p2

I made a test e0.0 device to test the theory:

brw-rw----  1 root disk 152,    0 Feb  3 11:30 e0.0
brw-rw----  1 root disk 152,    1 Feb  3 11:30 e0.0p1

And I can assign that without problems.

My AOE minors go well up into the thousands - is there a workaround?

Thanks,
Dave
