Hi Shane,
We (Bloomberg) have many large clusters and we currently use Ubuntu. We
have just recently upgraded to Trusty (14.04). Our new super object store
that we're building out is using Trusty but we may switch to RHEL because
of other departments joining in - final decision has not been made.
However, our OpenStack clusters will stay Ubuntu.
Thanks,
Chris

I'm seeking some input from people that have been running larger Ceph
clusters ... on the order of 100s of physical servers with thousands of
OSDs in them. Our primary use case is Object via Swift API integration and
adding Block store capability for both OpenStack/KVM backing VMs, as well
as general use for various block store scenarios.
We'd *like* to look at CephFS, and I'm heartened to see a kernel module
(over the FUSE based), and a growing use base around it, and hoping
production ready will soon be stamped on CephFS ...
We currently deploy Ubuntu (primarily Trusty - 14.04), and CentOS 7.1.
Currently we've been testing our Ceph clusters on both, but our preference
as an organization is CentOS 7.1.1503 (currently).
However - I see a lot of noise in the list about needing to track the more
modern kernel versions as opposed to the already dated 3.10.x that CentOS
7.1 deploys. Yes, I know RH and community backport a lot of the newer
kernel features to their kernel version ... but ... not everything gets
backported.
Can someone out there with real world, larger scale Ceph cluster
operational experience provide a guideline on the Linux Distro they
deploy/use, and works well with Ceph, and is more inline with keeping up
with modern kernel versions ... without crossing the line in to the
bleeding and painful edge versions ... ?
Thank you ...
