Hi, Is there some tool or method in centos that can limit cpu usage to some percentage for specified processes that consume large cpu resource? I found cpulimit which is only able to limit one process. what I want is one tool that can limit several same processes' cpu usage. Thanks! Regards andrew

Adding Mohit who is experimenting with cgroups has found some way to restrict glustershd's CPU usage using cgroups. Mohit maybe you want to share the steps we need to follow to apply cgroups only to glustershd. Thanks.

Hi, community I have a large distributed-replicated Glusterfs volume, that contains few hundreds VM's images. Between servers 20Gb/sec link. When I start some operations like healing or removing, storage performance becomes too low for a few days and server load becomes like this: 13:06:32 up 13 days, 20:02, 3 users, load average: 43.62, 31.75, 23.53. Is it possible to set limit on

Hi, As told in "Control Groups Resource Management" libvirt page : Legacy cgroups layout Prior to libvirt 1.0.5, the cgroups layout created by libvirt was different from that described above, and did not allow for administrator customization. Libvirt used a fixed, 3-level hierarchy libvirt/{qemu,lxc}/$VMNAME which was rooted at the point in the hierarchy where libvirtd itself was
