-2.6.32-5-xen-amd64
Thanks Guido for your answer.
I haven't seen this report.... oups..
I have add the "squeeze-proposed-updates" in the sources.list and i have update
the package linux-image-2.6.32-5-xen-amd64 - 2.6.32-31 to 2.6.32-34
All of my test script works fine now. No bug with the lvcreate and lvremove..
Regards,
Remi
Hi Remi,
great to hear it's working for you.
Did you leave the proposed-updates active on your server or did you use it only
once to install the linux-image packet and made it inactive afterwards?
I'm a bit unassured using them on a production server.
Regards
Guido
Hi,
have the same bug here!
It should be fixed as:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=614400
I'm not 100% shure but the fix should be available under proposed updates for
squeeze.
You can activate them under /etc/apt/sources.list
Add something like this to include "proposed updates"
# deb http://ftp-stud.hs-esslingen.de/debian squeeze-proposed-updates main
non-free contrib
I didn't try it in production environment until now and don't know which
impacts it might have to "mix" different deb sources.
Regards
Guido

Hello list,
I have met a Bug in the debian squeeze with the kernel 2.6.32-5-xen-amd64 and
Xen 4.0.1
I have try with two differents environement, but i have the same result...
I haven't this bug when i use just the kernel 2.6.32-5-xen-amd64 without the
hypervisor Xen 4.0.1 and on the debian lenny with the kernel 2.6.26-2-xen-amd64
+ Xen 3.2.1.
When i run a script who create a snapshot of a LV, i have this Bug error:
Just after the "lvcreate -s -n Snap -L 1G /dev/data/svsqueeze" in the script
