You can use it for other things, but I wouldn't recommend it. If you 
really want to, just be careful not to confuse volumes: PVE uses LVM 
tags to identify its volumes, but for added safety avoid calling *your* 
volumes "vm-XXX-disk-Y".

No dancers here, but check back on a Saturday night. ;)

Jokes aside, I prefer to avoid LVM mirrors as they are a relatively 
recent addition, not as tested as MD mirrors and besides I don't like a 
few things about the implementation. Anyway, software RAID is not 
supported by the Proxmox team: use hardware RAID with battery-backed 
cache if you care about performance.
