you mean create multiple top level directories on a mounted files system and use each directory as a brick in a different volume?
if the underlying block device is a thinly provisioned lvm2 volume and you want to use snapshots you cannot do this, otherwise I don't think there is a technical reason you can't other than the obvious that this is in general not a good idea as use in one volume may impact the available storage for a different volume and it will not be transparent how much each volume is consuming.
I have three servers each with 40Tb of disk in an external sas enclosure. The storage is presented as a RAID 6 VD and I then make that a physical volume and created a lvm2 Volume Group on top. Individual bricks are thin provisioned logical volumes.

Gluster users,We have a multiple node setup where each server has a single XFS brick (underlying storage is hardware battery backed raid6). Are there any issues creating multiple gluster volumes using the same underlying bricks from a performance or management standpoint?or would it be better to setup many smaller bricks via RAID1 to support multiple volumes.Current setup:NODE:/brick1 (raid6 8 disk per brick)Smaller Brick setup:NODE:/brick1 /brick2 /brick3 /brick4 (raid1 2 disk per brick)
