Hi All,
--
Status update on "Hyperconverged Gluster oVirt support"
Features Completed:
================
cockpit-ovirt
-------------
1- Asymmetric brick configuration.Brick can be configured per host basis i.e. If the user wanted to make use of sdb from host1, sdc from host2, and sdd from host3.
2- Dedupe and Compression integration via VDO support (see https://github.com/dm-vdo/kvdo). Gluster bricks are created on vdo devices
3- LVM cache configuration support (Configure cache by using fast block device such as SSD drive to imrove the performance of a larger and slower logical volumes)
4- Auto addition of 2nd and 3rd hosts in a 3 node setup during deployment
5- Auto creation of storage domains based on gluster volumes created during setup
6- Single node deployment support via Cockpit UI. For details on single node deployment - https://www.ovirt.org/documentation/gluster-hyperconverged/chap-Single_node_hyperconverged/
7- Gluster Management Dashboard (Dashboard will show the nodes in cluster,Volumes and bricks. User can expand the cluster and also can create new volume in existing cluster nodes )
oVirt
-------
1- Reset brick support from UI to allow users to replace a faulty brick
2- Create brick from engine now supports configuring an SSD device as lvmcache device when bricks are created on spinning disks
3- VDO monitoring
GlusterFS
---------------
Enhancements to performance with fuse by 15x
1. Cluster after eager lock change for better detection of multiple clients
2. Changing qemu option aio to "native" instead of "threads".
end-to-end deployment:
--------------------------------
1- End to end deployment of a Gluster + Ovirt hyperconverged environment using ansible roles ( https://github.com/gluster/gluster-ansible/tree/master/playbooks ). The only pre-requisite is a CentOS node/oVirt node
Future Plan:
==========
cockpit-ovirt:
1- ansible-roles integration for deployment
2- Support for different volume types
vdsm:
1- Python3 compatibility of vdsm-gluster
2- Native 4K support
Thanks,
Gobinda
