[Gluster-users] one brick vs multiple brick on the same ZFS zpool.
Hi, Since I am new with Gluster, need your advices. I have 2 different Gluster configuration: Purpose: Need to create 5 Gluster volumes. I am running the gluster version is 3.9.0. Config #1: 5 bricks from one zpool 3 storage nodes. Using hardware raid to create one array with raid5 (9+1) per storage node Create a zpool on top of the array per storage node Create 5 ZFS shares (each share is a brick) per storage node Create 5 volumes with replica of 3 using 5 different bricks. Config #2: 1 brick from one zpool 3 storage nodes. Using hardware raid to create one array with raid5 (9+1) per storage node Create a zpool on top of the array per storage node Create 1 ZFS shares per storage node. Using the share as brick. Create 5 volumes with replica of 3 with same share. 1) Is there any different on the performance on both config? 2) Will the single brick be handling parallel writing vs multiple brick? 3) Since I am using hardware raid controller, any option that I need to enable or disable for the gluster volume?

Hardware raid with ZFS should avoided ZFS needs direct access to disks and with hardware raid you have a controller in the middle If you need ZFS, skip the hardware raid and use ZFS raid Il 6 mar 2017 9:23 PM, "Dung Le" <vic_le at icloud.com> ha scritto:> Hi, > > Since I am new with Gluster, need your advices.
