[ovirt-users] Re: Poor I/O Performance (again...)

Hi, Thank you Alex, I was looking for some optimisation settings as well, since I am pretty much in the same boat, using ssd based replicate-distributed volumes across 12 hosts. Could anyone else (maybe even from from ovirt or rhev team) validate these settings or add some other tweaks as well, so

[ovirt-users] Poor I/O Performance (again...)

[ovirt-users] Re: Tuning Gluster Writes

Some kernels do not like values below 5%, thus I prefer to use vm.dirty_bytes & vm.dirty_background_bytes. Try the following ones (comment out the vdsm.conf values ):vm.dirty_background_bytes = 2vm.dirty_bytes = 45000 It's more like shooting in the dark , but it might help. Best Rega
