pve-kernel-3.10.0-3-pve does not work on 2 of 4 systems

Hello,
Soon I'll be setting up a ceph cluster.

Is it best to use the 3.10 Kernel from pve testing?

We will only use KVM on the test.

Re: ceph cluster - which kernel is best to use?

Since you are going to perform some tests and that a new release of Proxmox based on the 3.10 kernel only awaits the openvz patches for Redhat 7 to be published combined with your information that you will only use KVM I would suggest to use the 3.10 kernel.

Re: ceph cluster - which kernel is best to use?

since kvm/qemu uses userland librbd to interface with ceph, the kernel doesnt matter. As such I would recommend staying away from experimental kernels since its... well... experimental.

The ceph nodes itself as well as machines you want to use kernel RBDs on (non-KVM usage) benefit from having a 3.x kernel though. A safe recommendation would be 3.2 (debian wheezy).

we have two Dell Poweredge r720 with perc h710 raid controllers.

those systems have run pve for a year with out boot issues.

However they will not boot pve-kernel-3.10.0-3-pve .

from a pic taken at console:

...  megasas: INIT adapter done
  Volume group "pve" not found
  Skipping volume group pve
Unable to find LVM volume pve/root
Gave up waiting for root devices.   .....

can you try to add in grub.cfg

rootdelay=10

linux /vmlinuz-xxxx-pve root=/dev/mapper/pve-root ro rootdelay=10 quiet

try this, modify the /etc/default/grub from

GRUB_CMDLINE_LINUX_DEFAULT="quiet"
to
GRUB_CMDLINE_LINUX_DEFAULT="quiet scsi_mod.scan=sync"

and update gurb menu
#update-grub2
