Using elrepo (http://elrepo.org/tiki/tiki-index.php) by adding to your yum
repositories is much simpler than compiling your own kernel - Once you add the
repository:
1.) Install the kernel
yum install <kernel>
where <kernel> can be:
kernel-lt (long-term support kernel - http://elrepo.org/tiki/kernel-lt )
kernel-mt (mainline stable kernel - http://elrepo.org/tiki/kernel-ml )
2.) update your grub.conf to boot to the appropriate image (default=0, or
whatever kernel in the list you want to boot from).
3.) Reboot.
That's it! Piece of cake.
We're using the elrepo kernel-lt in a fairly limited fashion, but have not had
any issues with basic/normal rbd functionality. Very stable, performs well
(although we're not stressing it heavily).
Cheers!

Subject: [ceph-users] Which OS for fresh install?
I'm evaluating ceph for our new private and public cloud environment. I have a
"working" ceph cluster running on centos 6.5, but have had a heck of a time
figuring out how to get rbd support to connect to cloudstack. Today I found out
that the default kernel is too old, and while I could compile a new one in the
3.x series, I would rather look at switching to a newer OS that supports that
natively. I see that centos 7 is out now, and has the newer kernel I need.
Since we are just now starting the project, would it be better to go with
centos 7, or are there known issues that should push me to another distro
entirely?
