Yes, the only thing which brings the wirte I/O almost on my Host Level is by enabling viodiskcache = writeback. As far as i can tell this is caching enabled for the guest and the host which is critical if sudden power loss happens. Can i turn this is on if i have a BBU in my Host System?
I was referring to the set of gluster volume tunables in [1]. These options can be enabled through "volume set" interface in gluster CLI.
The quorum options are used for providing tolerance against split-brains and the remaining ones are recommended normally for performance.
