[Bug 703796] Re: aoe-stat only sees vblade minor numbers 0-15

2011-01-17 Thread Ivan Cauchi
update to the below.

I have a separate virtualised instance of OpenFiler v2.3.  On the
OpenFiler, vblades from the Ubuntu servers with minor numbers 0 up till
254 can be viewed by aoe-stat (but not 255).  This is completely
different behaviour from the aoe-stat behaviour experienced on the
Ubuntu installation.

The OpenFiler 2.3 is based on RedHat with kernel version
2.6.26.8-1.0.11.smp.pae.gcc3.4.x86.i686.  I couldn't determine the
package version of aoetools, however /sys/module/aoe/parameters/version
contains the number '64'.

On my Ubuntu 10.4.1LTS machines, the file /sys/module/aoe/version
contains the number '47'.

[Bug 703796] [NEW] aoe-stat only sees vblade minor numbers 0-15

2011-01-16 Thread Ivan Cauchi
Public bug reported:

Binary package hint: aoetools

I have two Ubuntu 10.4.1 LTS servers installed with the aoetools, vblade
and vblade-persist packages added to both.

I have set up LVM partitions on both machines that are being exported
using vblade-persist, using various major and minor numbers.  I'm then
using aoetools on each machine to view the vblades on the other one.

What I found interesting was that although I could export partition
targets using any minor number (it is reported that one could use
between 0 and 255), I found that on the initiator machine, aoe-stat only
reports block devices if the minor number is between 0 and 15.

What was strange was that other vblades with minor numbers  15 (e.g.
16, 19, 20, 99 etc) could be viewed correctly on the initiator machine
using aoeping.  However aoe-stat refused to acknowledge their existence,
even after forcing an aoe-discover.

I was expecting the aoe initiator to be able to view any minor number on
the vblade target.

I am using the following packages

aoetools 30-3ubuntu1
vblade 20-1ubuntu1
vblade-persist 0.6-2

on the 2.6.32.27-generic kernel.
