Mount.lustre will try to tune max_sectors_kb, scheduler automatically for OSTs in default.
This could cause some unexpected behavior if there are external tools which try to do same
things using udev rules etc, as lustre could use raw block device or be on the top of logical (N logical) devices and as a result this tunings on fly will be a result of excellent butthearts
especially when tuning comes from storage.
In order to solve this problem, it makes sense to add a mount option like no_auto_tune
etc to disable automatically tune by mount.lustre util.
