[ovirt-users] Re: Sharding decision for oVirt

Good day, the distributed volume was created manually. currently i'm thinking to create a replica on the two new servers which 1 server will hold 2 bricks and replace it later, then recreate the brick for the server hosting 2 bricks into 1, also i found the image location /gluster_bricks/data/data/19cdda62-da1c-4821-9e27-2b2585ededff/images but not sure how to transfer it to a new instance of engine On Mon, May 10, 2021 at 4:49 PM Strahil Nikolov via Users <users(a)ovirt.org&gt; wrote: > A quote from : > https://access.redhat.com/documentation/en-us/red_hat_gluster_storage/3.5... > > > Sharding has one supported use case: in the context of providing Red Hat > Gluster Storage as a storage domain for Red Hat Enterprise Virtualization, > to provide storage for live virtual machine images.
