Works as expected, doesn't it? What do you want to exactly achieve with local storage? j.

It does work as expected, do your homework first to know how oVirt does work. Your expectation are just your expectations. Question: How would you migrate a VM in a cluster with local storage? Wouldn't glusterfs solve the issue? It can use those SSDs...

If I try to create local storage, it works, but then host is in separate Data Center. If I try to add POSIX FS to node in existing Data Center, then all other hosts stop working, since they can't access that local storage (kind of expected). So, long story short - does shared and local storage mix and how?
