Has anyone compiled ceph (either osd or client) on a Solaris based OS? The thread on ZFS support for osd got me thinking about using solaris as an osd server. It would have much better ZFS performance and I wonder if the osd performance without a journal would be 2x better.
Doubt it. You may be able to do a little better, but you have to pay the piper some how. If you clone from journal you will introduce fragmentation. If you throw the journal away you'll suffer for everything but very large writes unless you throw safety away. I think if we are going to generally beat filestore (not just for optimal benchmarking tests!) it's going to take some very careful cleverness. Thankfully Sage is very clever and is working on it in newstore. Even there, filestore has been proving difficult to beat for writes.
A second thought I had was using the Comstar iscsi / fcoe target software that is part of Solaris. Has anyone done anything with a ceph rbd client for Solaris based OSs?
No idea!
