hi, I found a more serious issue with cgmanager.
# start a zfs based container container $ lxc-start -d -n redmine # stop it $ lxc-stop -n redmine # rename it: it gets unmounted, but cannot be renamed nor remounted $ zfs rename tank/lxc/redmine tank/lxc/r cannot rename 'tank/lxc/redmine': dataset is busy filesystem 'tank/lxc/redmine' is already mounted cannot mount 'tank/lxc/redmine': Resource temporarily unavailable $ stop cgmanager cgmanager stop/waiting/ # rename successfull $ zfs rename tank/lxc/redmine tank/lxc/r $ zfs rename tank/lxc/r tank/lxc/redmine # mount dataset $ zfs mount tank/lxc/redmine # container cannot get started $ lxc-start -d -n redmine lxc-start: command get_cgroup failed to receive response # if cgmanager is started, container is starting successfully $ start cgmanager cgmanager start/running, process 25740 $ lxc-start -d -n redmine # if it matters: zfs dataset contains both rootfs AND configs $ ls /tank/lxc/redmine/ config fstab rootfs rootfs.hold 1. zfs dataset is locked by cgmanager for some reason after lxc-stop. 2. lxc-start fails if cgmanager isn't running (just a note, it's could be intentional) Thanks, tamas _______________________________________________ lxc-users mailing list [email protected] http://lists.linuxcontainers.org/listinfo/lxc-users
