Hello, I'd like to introduce a RFE that allows to use a local storage in multi server environments https://bugzilla.redhat.com/show_bug.cgi?id=1406412
Most servers have a local storage. Some servers have very reliable storages with hardware RAID controllers and battery units. Example user cases: https://www.mail-archive.com/[email protected]/msg36719.html https://www.mail-archive.com/[email protected]/msg36772.html The best way to use local storage in multi server "shared" datacenters is exporting it over NFS. Using NFS allows to move disks and VMs among servers. In order to improve performance, disk I/O bound VMs can be pinned to a host with local storage. However there still is a performance drawback of NFS layers. Treating a local NFS storage as a local storage improves performance for VMs pinned to host. Currently setting up of NFS exports is out of scope of oVirt. However this would be a way to get rid of "Local/Shared" storage types of datacenter. So that all storages are shared, but local storages are used as local. Any questions/comments are welcome. Specifically I'd like to request for comment on potential data integrity issues during online VM or disk migration between NFS and localfs.
