Building a small Ceph development environment

Building a small Ceph development environment

[Terrance Hutchinson]

Hi all,

I have an HP ProLiant ML350 G5 server that is currently sitting idle
at the moment. Would it be possible to virtualize a Ceph cluster so I
can mess around and begin contributing back to the community?

Specs:

ML350 G5
2 x Quad Core Xeon E5430
16GB RAM
7x 146GB SAS disks
1x 120 GB Intel 520 SSD
HP P800 Smart Array Controller (can purchase an LSI 208E SAS HBA which
will make the disks a JBOD)

My goal is to create a small Ceph setup to do testing and bug fixes
for the project which is why I posted this to the development list.

Thanks in advance,
Terrance

You don't need to virtualize anything — I'd recommend running Ubuntu
12.04 on it (you don't need to, but a lot of things will be more
performant), building from source, and then setting up the daemons so
everybody gets a separate disk.
Check out http://ceph.com/docs/master/source/ and the other docs and
let us know if you have any questions. :)

Yeah, it's certainly doable to run all the daemons on one server; they 
don't even really need a separate disk, but that's generally a nice 
partitioning.

You can usually get help on irc://irc.oftc.net/#ceph, too.

Everything works out, but because RHEL6 lacks syncfs support your performance will be less predictable. If you have more than one OSD on a box without syncfs() support you'll certainly want to run btrfs if you can.  
(Ceph daemons are very concerned with their data integrity — for the obvious reasons — and so they spend a lot of time making sure stuff goes on disk in the right order. Newer kernels and userspace environments provide more tools for doing this without doing a full sync() system call.)
