Hello,
I am using libcg 0.41 and Linux Kernel 3.2.0.4 (AMD 64) on Debian 7.
When I am using memory controller (and some others) through the following
config file :
---
mount {
cpu = /cgroup/cpu;
freezer = /cgroup/freezer;
net_cls = /cgroup/net_cls;
blkio = /cgroup/blkio;
memory = /cgroup/memory;
}
---
the cgroup_get_cgroup() function is returning an error "Cgroup invalid
operation".
The error seems to be emitted from cgroup_add_controller() which will
return on this case :
/*
* Still not sure how to handle the failure here.
*/
for (i = 0; i < cgroup->index; i++) {
if (strncmp(name, cgroup->controller[i]->name,
sizeof(cgroup->controller[i]->name)) == 0)
{
return NULL;
}
}
When commenting the memory controller line, the error disappear.
I have also tried to output all debug messages available in libcg, but none
of these seems related to this issue.
What can cause this issue ?
Best regard,
|
