Subject: [linux-lvm] raid0 - no performance increase??
Date: Sat, 10 Oct 2020 17:52:32 +0100	[thread overview]
Message-ID: <> (raw)

Hi guys,

I have a simple raid0 lvm comprising of two NVME devices.
I'd expect performance of such a volume to be higher than a
"regular" volume ran of a single NVME, but simple dbench
shows such raid0 volume to the same "slow" as a single NVME
The system is a Centos 8 with 5.8.14-1.el8.elrepo.x86_64 and
default kernels.

  #Str #DStr Stripe Type   Devices                   
     2     2 64.00k raid0  0_rimage_0(0),0_rimage_1(0)
     1     1     0  linear /dev/nvme0n1(0)           
     1     1     0  linear /dev/nvme1n1(0)

Care to share your thoughts? I'll be grateful.
many thanks, L
