And both of these are categorized as 'low_prio' operations by io-threads. Setting low-prio-threads to 32 saw some improvement in performance in initial testing done by Paul Cuzner. 2. cluster.locking-scheme=granular This is needed for more granular locking during entry self-heal so that parallel heal-info doesn't hang until heals are complete. 3. features.shard=on This is needed to reduce heal-times of VM image files which are large files whose size can range anywhere from a few GBs to TBs or even PBs. 4. cluster.shd-max-threads=8, cluster.shd-wait-qlength=10000 These are to leverage multi-threaded self-heal feature to get better heal performance and minimise the effect of downtime on VM file consistency and availability. 5. user.cifs=off We support access to files in virt use case only through libgfapi and FUSE. So we explicitly disable other methods of access such as cifs. --- Additional comment from Worker Ant on 2017-02-17 05:44:01 EST --- COMMIT: https://review.gluster.org/16577 committed in master by Niels de Vos (ndevos) ------ commit 932ff80b57846ed77b66776ade575a0b2231183a Author: Krutika Dhananjay <kdhananj> Date: Thu Feb 9 15:56:04 2017 +0530 extras: Add more options to group virt Apart from some of the option configurations already listed in the group-virt.example file, we also recommend that the users set certain other options added by this patch for VM use-case. This also helps Gluster-oVirt users in configuring virt options for new volumes at the click of a button as opposed to setting them manually through volume-set command.
