Proxmox 2.0 Beta HA Config validation error

[argonius]

Hi,

i've upgrade to the newest beta and tried to test HA Failover.
I've created a simple kvm vm with id 100. disk images resides on a shared glusterfs storage
and is accessible on node1 and node2.
after that i've gone to Datacenter->HA and created an HA for this vm. then i clicked commit
and received:
config validation failed: unknown error (500)

i don't know how to handle this error message

below some version informations:

I doubt that gluster is suitable for storing disk images and HA, at least I personally never used it and so far no one reported this setup as fast and reliable against failures. but some reported the opposite.

As a general rule, always use stable and well tested storage technologies for HA, and gluster is not on my personal list.

hi,

thanks for fast reply. I can not follow why glusterfs should not be stable. we are using it in many productive setups w/o problems :/
i figured out my problem. i still missed pve-resource-agents package. after installing it seems to work finde now

thx

can you provide details about your gluster setup? any performance benchmarks for your virtual disks stored on gluster? on Proxmox VE, its not a "stable and widely used" storage technology, also not on other virtualization platforms - but I really like to see good working systems with gluster, but so far no one showed one to me.

great, thanks for feedback - and as far as I see this already documented in the wiki.

if i finished my setup to a working one, i will provide you with data
i am still struggeling with rgmanager. also i am getting a segfault:

# ccs_tool lsnode -v

Cluster name: Cluster1, config_version: 3


Nodename Votes Nodeid Fencetype
proxmox1 1 1
Segmentation fault

looks like fencing is really needed, so i will try to setup first fencing with SuperMicro ipmi and looking forward

argonius,

Do you have any benchmarks you can provide? I've been considering a few different distributed storage technologies, among them Gluster, Sheepdog and Ceph and it would interesting to know what your experience has been with Gluster so far.
