[lxc-users] blkio.weight cgroup problems

[Andre Nathan]

Hi

I'm running a few hundred containers for my customers, which are limited
in CPU and memory use according to their plan. I'm trying to introduce
I/O limits via blkio.weight so that the basic plan has weight 1000, the
next plan has weight 1100, then 1200 and so on.

I've added "lxc.cgroup.blkio.weight = 1000" (or the appropriate weight)
to the containers' config file and restarted them, but after around 200
containers were succesfuly restarted, I started getting this error on
lxc-start:

lxc-start: cgmanager.c: cgm_setup_limits: 1238 call to
cgmanager_set_value_sync failed: invalid request

lxc-start: cgmanager.c: cgm_setup_limits: 1241 Error setting cgroup
blkio:lxc/c1 limit type blkio.weight

Has anyone seen anything similar?

I'm using LXC 1.07 and cgmanager 0.24 (Ubuntu 14.04).

Thanks,
Andre
