It seems that during the history of the DC, there wasn't one time we really used the DRDB features and it makes our storage configuration more complex and hard to maintain/debug than it brings value.

Lets think on a new SIMPLE storage setup that will increase the availability of oVirt services and will prevent incidents like before where we have a single point of failure if the storage is down. without multiple services that adds more failure points and complexity to the setup.

One suggestion was to install 2 new storage servers running ISCSI and connect them independently to oVirt and spread the load over both of them, so if one is down the other will keep running.

We can consider having a few redundant VMs on both servers if possible like the resources server and maybe others as well.

Please add more suggestions on this ticket, it should be our number one priority right now.
