Description Ramesh N 2015-03-13 07:01:27 UTC 
Description of problem:
 Currently dirty_ratio and dirty_background_ratio is changed to 5, 2 from RHEL's default 20, 10. But RHS performance teams suggest to keep it same as in RHEL for RHS.

 Tune the dirty_ratio and dirty_background_ratio accordingly to the values suggested by the RHS performance team:

vm.dirty_ratio=20
vm.dirty_background_ratio=10
Comment 2 Bala.FA 2015-03-13 08:54:06 UTC 
The fix is done by removing settings in /etc/sysctl.d/vdsm.conf file.
