I'm pretty excited by the new write-around cache policy for librbd && io scheduler:)
(better than writeback, no read latency impact :) librbd now uses a write-around cache policy be default, replacing the previous write-back cache policy default. This cache policy allows librbd to immediately complete write IOs while they are still in-flight to the OSDs. Subsequent flush requests will ensure all in-flight write IOs are completed prior to completing. The librbd cache policy can be controlled via a new “rbd_cache_policy” configuration option. librbd now includes a simple IO scheduler which attempts to batch together multiple IOs against the same backing RBD data block object. The librbd IO scheduler policy can be controlled via a new “rbd_io_scheduler” configuration option. ----- Mail original ----- De: "Thomas Lamprecht" <t.lampre...@proxmox.com> À: "pve-devel" <pve-devel@pve.proxmox.com>, "Victor Hooi" <victorh...@yahoo.com> Envoyé: Mardi 24 Mars 2020 14:00:30 Objet: Re: [pve-devel] Ceph Octopus is out!

I'd guess we get some testing stuff out in Q2/2020, depending on how well the changes in details play with our integration. As I know ceph, waiting on a stable point release, which should also include our dev testing feedback, will probably make sense to do. After all we want a smooth (upgrade) experience :) cheers, Thomas _______________________________________________ pve-devel mailing list pve-devel@pve.proxmox.com https://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-devel _______________________________________________ pve-devel mailing list pve-devel@pve.proxmox.com https://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-devel
