Hi,
I'll run few tests more today with running some copied production VM-s to be sure, that they will fail over during high writing and reading also.
We are just getting ready to move all of our production VM-s to gluster, so it'll be around 30 VMs on one site and 15 on other. These are not VM-s "for sale", we are using VM-s for our infrastructure. Both MS and Linux. Sizes are very different. 10-150 GB per VM. If it will be ok with gluster, we will try to run one with 2TB disks for owncloud.
I'm not sure about OpenVZ containers, will test that too. At least I'm sure, that containers do not run well on mounted glusterfs somewhere not in /var/lib/vz directory. But afaik there always been a problem with containers running not from /var/lib/vz directory, so this one is not tested yet.
I'll try to make simple benchmark tests during the self-heal process.

Wow, this is great news! Thanks a lot for sharing the results :-). Did you get a chance to test the performance of the applications in the vm during self-heal?
May I know more about your use case? i.e. How many vms and what is the avg size of each vm etc?

Here are the results.1. still have problem with logs rotation. logs are being written to .log.1 file, not .log file. any hints, how to fix?2. healing logs are now much more better, I can see the successful message.3. both volumes with HD off and on successfully synced. the volume with HD on synced much more faster.4. both VMs on volumes survived the outage, when new files were added and deleted during outage.
So replication works well with both HD on and off for volumes for VM-s. With HD even faster. Need to solve the logging issue.
Seems we could start production storage from this moment :) The whole company will use it. Some distributed and some replicated. Thanks for great product.

That is great Kaleb. Please notify semiosis as well in case he is yet to fix it.

Checking with Kaleb on this.

glfsheal isn't in our 3.5.2-1 DPKGs either. We (meaning I) started with the 3.5.1 packaging bits from Semiosis. Perhaps he fixed 3.5.1 after giving me his bits.
I'll fix it and spin 3.5.2-2 DPKGs.
