The cache will not take immediately into effect. It is designed to save your
cache disk and to load only repetitive data.
Try to run your benchmark 20 times and you will notice slight improvement over
reading the same object.
Of course , you can use lvm cache in writethrough mode, but then it i
So i created the brick without the cache an add the cache doing the commands
below; but it appers it's not working because I see no improvement in the
benchmarks.
pvcreate /dev/md/VMStorageHot
vgextend RHGS_vg_VMStorage /dev/md/VMStorageHot
lvcreate -L 1500G -n lv_cache RHGS_vg_VMStorage /dev/m

Did you blacklist in /etc/multipath.conf all local disks ?In other words, when
you run 'lsblk' do you see hte disk to have a child device (usually the wwid) ?
