Just to check I have this straight:
- Proxmox cluster using GlusterFS for storage
- bricks on Proxmox nodes
- Linux VM's running on Proxmox Nodes
- InnoDB running on the linux vms

When one of the proxmox nodes crashes (Power outage?) the InnoDB database is hosed?

We run multiple MS SQL servers in the same setup and a few mysql, never had that problem with them after server outages.

- Replica 3?
- Could you post your gluster info?
- Whats the underlying filesystem for the bricks? ZFS? What sync mode does it have set?
- Whats the KVM cache mode?
