Hi, It's important for disk alignment. If the Web UI doesn't have the option, I can recommend you to deep dive into the cli or use the ansible role from the engine. Just follow https://access.redhat.com/documentation/en-us/red_hat_gluster_stor...

My setup is DELL RAID Controler PERC H710 4 SSD disks raid5 Default stripe for Dell RAID-controller defaults is 64KB. I have no choice of a Raid 5 and if I choose Raid6, 4 or 3 disk, 64KB or 128KB Stripe. It does not work, (Failed to create brick data_ssd on host xxx of cluster Default). The only option that works is RAID type = None tried to find information about this, but no luck yet.. I tried ovirt engine 4.4.1.10 and lastest 4.4.7.6 Can I leave this to None ? Performance ?
