Hi all , We run into a big problem while using gluster(2.0.6) to serve kvm images and other stuff like mail storage in distrubted mode with only 1 server(we will add more in the future) . The problem is basicly when say 3 KVM VPS's using intesing IO applications It doesnt happen all the time but when happen it uses all gluster server IO and other servers that need access to the mail storage for example freezes . Normaly on local disk the sulotion is ionice but as i understand it only work on local block devices and not on network mounts . Anyone has any idea to overcome this e.g limit IO for clients or clients applications like kvm images ? this is a real IO problem wich makes the all storage crowl . Many thanks ,
