[ovirt-users] what is the best practices to delete vdisks in 100% used gluster stoargedoamin

Hi Team In my one of three node Hyperconverged (gluster + ovirt) setup, one of the storage domain went offline from Datacenter due to 100% storage space utilization, but luckily it is still online in Gluster. how should I properly delete some of the vdisks in that offline stoarge domain from Gluster and bring back to online?
