BoF - Gluster for VM store use case

[Sahina Bose <sabose@xxxxxxxxxx>]

During Gluster Summit, we discussed gluster volumes as storage for VM images - feedback on the usecase and upcoming features that may benefit this usecase.

Some of the points discussed

* Need to ensure there are no issues when expanding a gluster volume when sharding is turned on.

* Throttling feature for self-heal, rebalance process could be useful for this usecase

* Erasure coded volumes with sharding - seen as a good fit for VM disk storage

* Performance related

  ** accessing qemu images using gfapi driver does not perform as well as fuse access. Need to understand why.

  ** Using zfs with cache or lvmcache for xfs filesystem is seen to improve performance

If you have any further inputs on this topic, please add to thread.

thanks!
