Hi,
Are there any solutions for HA in SME?
I want to set up some kind of cluster mirroring two identical systems and provide failover.
I found some old threads about it and even a How-to but nothing for the newer versions.
Thanks,

Hi,
I did a quick and dirty search and found:
http://www.linbit.com/support/drbd-8.3.7/rhel4/
or from the repos..
yum install drbd kmod-drbd --enablerepo=extras
Thats maybe helpful.
Cheers! :smile:

I would suggest you to change the point of view: create a cluster with proxmox ve (search it with google, I've been asked to not link it here.. boh) and then create a virtual machine with SME
in this way you'll have hardware HA and you can recover your virtual machine in seconds/minutes..

Hi Stefano,
Du you use Proxmox ?
-
I would be interested to hear some experience from those who run SMEserver on Proxmox.
We had a brief look at Proxmox only (and might have given up too early). Judging on their web presence, it appears to be a well developed and maintained product. They do have a Wiki document for an SME8 (beta 4) installation at that time which requires several manual setup changes and is a bit technical or requires good Proxmox knowledge.
They also talk about dependency problems with the php version (5.2.10) from SME8 which probably put me off - but maybe too early. I would like to find an alternative to VMware server ESXi (which works very well but has no suitable backup or UPS support in its freely available version).

Stefano, do you have any financial interest in Proxmox. You mention it often, so I just wonder ...

hi Charlie...
no, I haven't any interest in proxmox.
I think it's a very good product.. I've seen it in production.. a multinode cluster.. I've seen live migration of virtual machines, online backup.. it's easy to install, easy to manage, very reliable.. I think it's far better than esx.. and easier to maintain.. finally, it's free, OOSS and with a good community.. :-)

Hi Stefano
Thanks for that feedback which ticks all the boxes for me. I will definitely look into that product again.

Thanks for the clarification.

Hi,
Proxmox is a nice virtualization platform that I have worked with before. But it's only good for experimentation and to serve maybe a small office.
Thank you for all the comments, I'm experimenting a few alternatives right now and will report back and if I find a solution.
Any other comments are also welcomed.
Best,

please define, I'm just curious.. I've seen a 6 nodes cluster with many, many virtual machines and storage on a separate SAN.. I think this is not a small office ;-)

You could also try the RH CLuster suite (on centOS)

Hi Stefano,
Thanks for the feedback, I'll look into the RH Cluster solution.
About the Proxmox experience, I rather not comment since you had better results. Myself, I'll wait for version2 to try it again ;)
Best,
