cat /sys/block/md1/queue/scheduler none

I don’t know what that means as a scheduler.

  PV /dev/md1   VG vg00   lvm2 [1.63 TiB / 0    free]
  Total: 1 [1.63 TiB] / in use: 1 [1.63 TiB] / in no VG: 0 [0]

Disks are in software RAID-10...

Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] 
md1 : active raid10 sdb2[1] sdc2[2] sdf2[5] sde2[4] sdd2[3] sda2[0]
      1754786304 blocks super 1.2 512K chunks 2 near-copies [6/6] [UUUUUU]

This raid stuff does not mean anything to me. Are these the ones for the active raid10 sdb2[1] sdc2[2] sdf2[5] sde2[4] sdd2[3] sda2[0]

It is not clear what is being asked here. What is the problem? –  aquaherd May 7 '13 at 20:19
I have a filesystem that I would like to change the scheduler on: /dev/mapper/vg00-var 1.6T 6.1G 1.6T 1% /var /dev/mapper/vg00-var on /var type ext4 (rw) I am trying to figure out what the block device is to change the scheduler. –  raid_confused May 7 '13 at 21:02
It looks like this is an XY Problem (see meta.stackoverflow.com/questions/66377/what-is-the-xy-problem) - what problem are you trying to solve? –  jackweirdy May 8 '13 at 21:12
