Hello!

I have a small request about Proxmox kernel. Current Proxmox kernel have a small bug, related with rotational attribute inheritance.
Now rotational attribute don't inherit in underliying devices (LVM). So if i have a SSD on host system with queue/rotational attribute = 0 and export that drive to guest system as lvm volume - in guest that attr will be = 1. In that case my udev schedulers rules works wrong. Of course i will setup scheduler for SSD manualy but i have several hundreds of hosts. And I'm lazy :-) so puppet work for me. But in 3.2 kernel that bug was resolved and inheritance work OK.
This small patch - http://git.kernel.org/?p=linux/kern...ff;h=4693c9668fdcec229825b3763876b4744f9e6d5e
Could Proxmox maintainers apply this patch to current kernel, please!

Many thanks!

Our kernel already includes that patch.
Click to expand...

Hmm, it's strange situation...
Now i use 2.6.32-14-pve #1 kernel and and non-rotation flag works wrong.

I have a RAID with two SSD and that MD device has a rotational attibute =1
But SSD has not

cat /sys/block/sdc/queue/rotational
0
cat /sys/block/sdd/queue/rotational
0

But

cat /sys/block/md2/queue/rotational
1

Maybe a kernel from pvetest included this patch?
