Hello everyone, I have two things that i really need to understand regarding storage scaling using gluster. Basically, I am trying to figure out a way to go from 1 single instance to multiple nodes cluster. 1. Single node SelfHosted Engine HyperConverged setup - scale instance up to 3 nodes: - the gluster volumes are created as distributed type. - is there a procedure to migate this single-host scenario to multiple nodes, considering that the 3 nodes setup is using replica 3 gluster volumes ? 2. 3 Nodes SelfHosted Engine - add more storage nodes - how should I increase the size of the already present replica 3 volumes ? - should the volumes be as distribute-replicated in an environment larger than 3 nodes ? 3. Is there a limit as a maximum number of compute nodes per cluster ? Thank you very much ! Leo -- Best regards, Leo David

Distribute volume can be changed to a replica 3 volume - but ensure there's no ongoing I/O. The easier process is to add new replica 3 volumes and move your VM disks to it - for the VMs that require HA. > > >> >> 2. 3 Nodes SelfHosted Engine - add more storage nodes >> - how should I increase the size of the already present replica 3 >> volumes ? >> - should the volumes be as distribute-replicated in an environment >> larger than 3 nodes ? >> > > Couldn't find documentation on ovirt.org site, but this should apply to > your case: https://access.redhat.com/documentation/en-us/red_hat_ > hyperconverged_infrastructure/1.1/html/maintaining_red_hat_h > yperconverged_infrastructure/scaling#scaling_rhhi_by_adding_ > additional_volumes_on_new_nodes > Sahina, can you help preparing some documentation for ovirt.org as well? > Sure, contributions are welcome though - Leo, if you feel like pitching in > >> >> 3.
