[ovirt-users] When creating a gluster brick in oVirt, what is the reason for having to fill in the RAID-parameters?

[Goorkate, B.J.]

Hi,

Thanks for confirming this!

Is there a preferred stripe size for gluster bricks? The default for RAID-10 
seems to be 256KB, but the Dell RAID-controller defaults to 64KB.

Regards,

Bertjan
