Cluster with Shared Nothing / no shared storage
- Thread starter Molch
- Start date
you can use a ceph/rbd storage.(officialy supported by proxmox 2.3).

Or a sheepdog cluster.

I don`t want to use a "Shared Storage" Solution.
Isn`t Sheepdog n' Ceph a shared storage technology?
so I guess Sheepdog is the way to go for me.
I tried the wiki tutorial but I got some errors like :
collie cluster format --copies=3
using backend farm store
Format failed: I/O error
and @ GUI

Sheepdog is not stable yet. I suggest you use ceph unless you want to actively develop sheepdog.
Note that sheepdog 0.6 have a stable branch now
https://github.com/collie/sheepdog/wiki/Stable-branches
So, they will maintain it and backports fix.
The plan seem to be release a new sheepdog version following the qemu release cycle each 3 months.
I don't known if they plan to do big changes in a near future. (0.6 break the cluster format for example).
So, currently, it's stable, but your need to be carefull when you upgrade, check the release notes,etc....
Thanks for clarification, but do not forget one important part - AFAIK you cannot get support for sheepdog (outside the community/dev lists). For ceph, you can commercial support and its used in production already at some places.
