One other question I have left (so far) is: I read and tried to follow
http://ceph.com/docs/master/install/rpm/ and
http://ceph.com/docs/master/start/quick-start/ on centos 6.3.
mkcephfs step fails without rbd kernel module.
I just tried to find "libvirt", "kernel", "module", and "qemu" on those
pages: "kernel" occurs in "add ceph packages" section and "module"
occurs in the header, footer, and the side menu. 0 hits for the others.
So when I read "after learning that qemu uses librbd (and thus doesn't
rely on the rbd kernel module) I was happy to stick with the stock
CentOS kernel for my servers (with updated qemu and libvirt builds)" --
forgive me for being dense, but I have no context for this. Where in
ceph.conf do I tell it to use qemu and librbd instead of kernel module?
Or does it mean I'm to set up my OSDs in virtual machines? Seems I'm
missing an important piece of information here (possibly because it's
blatantly obvious and is staring me in the face -- woudn't be the first
time).
So what is it that I'm missing?
TIA
Dima
