 |
|
Hallo zusammen,
folgendes Problem bei OpenVZ-Container nach einem Kernel-Update (*) stellt sich mir gerade:
| Code: | /etc/init.d/net.eth0 start
mkdir: das Verzeichnis „/sys/fs/cgroup/openrc“ kann nicht angelegt werden: Die Datei existiert bereits
mount: permission denied
mkdir: das Verzeichnis „/sys/fs/cgroup/cpuset“ kann nicht angelegt werden: Die Datei existiert bereits

mount: special device net_prio does not exist
* ERROR: sysfs failed to start
* ERROR: cannot start net.eth0 as sysfs would not start |
(*) = aktuell 2.6.32-openvz-042stab102.9-amd64, vormals 2.6.32-openvz-042stab094.8-amd64
Das Problem existiert erst seit der neusten Kernel-Version. Ich kann mir darauf nicht wirklich einen Reim machen, das diff zwischen den .configs halte ich für unbedenklich:

Weiterhin scheint es als wäre /sys problemlos gemountet:
| Code: | mount
/var/lib/vz/private/112 on / type simfs (rw,relatime)
proc on /proc type proc (rw,relatime)
sysfs on /sys type sysfs (rw,relatime)
tmpfs on /run type tmpfs (rw,nosuid,nodev,relatime,mode=755)
udev on /dev type devtmpfs (rw,nosuid,relatime,size=10240k,mode=755)
devpts on /dev/pts type devpts (rw,nosuid,noexec,relatime,gid=5,mode=620,ptmxmode=000)
shm on /dev/shm type tmpfs (rw,nosuid,nodev,noexec,relatime)
cgroup_root on /sys/fs/cgroup type tmpfs (rw,nosuid,nodev,noexec,relatime,size=10240k,mode=755)
/var/lib/vz/private/112 on /tmp type simfs (rw,noexec,relatime)
binfmt_misc on /proc/sys/fs/binfmt_misc type binfmt_misc (rw,nosuid,nodev,noexec,relatime) |
Hat jemand einen Ansatz für mich den ich verfolgen könnte? |

Ich konnte das Problem soeben lösen.
Auf Systemen, auf denen sysfs ein eigenes init-Script hat ( bin mal gerade zu faul heraus zu suchen ab welcher openrc-Version das der Fall ist ) muss in der rc.conf folgendes gesetzt sein:
| Code: | rc_controller_cgroups="NO"
|
Anschließend funktioniert wieder alles wie gehabt.
#Problemediedieweltnichtbraucht 
Edit:
Es scheint doch nicht zweifelsfrei anhand dessen festlegbar sein ob sysfs ein separates init-Script hat. An der Behebung des Problems ändert sich aber nichts. |

Nach den Updates von openrc und den udev-init-scripts fährt mein portage-server auch ohne die Anpassung in der rc.conf sauber hoch, sysfs wird korrekt eingehangen, Netzwerkschnittstellen fahren sauber hoch. |
