AFAIK, LVM is needed only if you use snapshots. Other then that, you
do not need it.
You can use RAID if you don't mind extra lost space.
You can test both configs and then choose the right one for your workload.

[Gluster-users] Gluster Disks configuration

[Mahdi Adnan]

Hi,


I have a question regarding disk preparation.

I have 4 nodes, each has 24 SSD, i would like to know whats the best practice 
to setup the disks.

The pool will be used as a vmware datastore.

im planning on using each disk as a brick without lvm, pool will be distributed 
replicas with sharding enabled, do you have any comments on this setup ? 
because i dont know if i should use all disks as one big disk with RAID and 
disable sharding, or use each disk as a brick with sharding enabled.


also, Redhat website stated that i have to use LVM, but i couldn't get an 
answer on why i should use LVM or why i should't.

"You should not create Red Hat Storage volume bricks using raw disks. Bricks 
must be created on thin-provisioned Logical Volumes (LVs)"
