[systemd-devel] CPUQuota setting is not inherited from systemd slices

[Oliver Graute]

Hello,

I try to limit my CPUQuota for my dnt5411software.slice. But the
services in the slice do not inherit the CPUQuota=20% setting from the
dnt5411software.slice file. They still consume more then 20% of the
CPU.

Some clue whats wrong or missconfigured here? I'am using systemd 225

[systemd-devel] systemd-222 mount issues on CentOS 7

[Lokesh Mandvekar]

Hi list,

I've re-built systemd-222 from Fedora dist-git sources for CentOS 7
(needed for rkt). This is part of the work I'm doing to provide rkt
as an rpm for CentOS Virt SIG. The koji build can be found here:
http://cbs.centos.org/koji/buildinfo?buildID=12569

On installation and reboot, I notice that systemd will only mount the
root dir successfully, while other discrete partitions (/home etc.)
will fail to mount.

# systemctl status local-fs.target
● local-fs.target - Local File Systems
   Loaded: loaded (/usr/lib/systemd/system/local-fs.target; static; vendor 
preset: enabled)

Warning: Journal has been rotated since unit was started. Log output is

Now, I can mount these partitions with:

# lvm vgchange -ay

but this still doesn't automount succesfully on a reboot.

Did I miss something here?

Thanks,

then don't use RunTimeDirectory in your mysqld-unit instead 
/etc/tmpfiles.d which would create the folder at boot

thanks, that seems to work.


systemd just does what you told it

thats true, but i did not realize what i told ;)

If that stuff needs to run so isolated, one could try packaging it as
an nspawn container...
