Linux md vs. LVM performance

I am trying to tune my NAS, running openfiler, and wondering why I’m getting relatively poor read performance from 4 WD RE3 drives in RAID 5.

EDIT: Please note I am talking about the buffered disk read speed not cached speeds

EDIT: Changed formatting to make clear there are two sets of output.

When I run hdparm on the meta device I get the levels of performance I’d…

If you can't recreate a volume (for example, I couldn't create a "backups" volume within the "raid10" volume group, run rm -r /mnt/raid10/backups to undo the mkdir command, then try to recreate the volume.

And if you can't delete a volume group from OpenFiler's web interface, get into the console and run the following commands:

1. vgchange -a n <volume group name here>     - you should see something that says, "0 logical volume(s) in volume group "<name>" now active

    - If you don't, then unmount the volume within the volume group and try again

2. vgremove <volume group name here>     - Type "y" when asked to verify your intent to remove the volume group

1. Install hdparm on OpenFiler:

    conary install hdparm

2. Run a benchmark test to get cache and disk read times:

    hdparm -Tt /dev/md0
