Can DRBD work in LXC Container? I already asked this in LXC-Users but they weren't sure.
I saw the following message which gave me the vague impression DRBD could be done in a container. http://lists.linbit.com/pipermail/drbd-dev/2011-March/001426.html I have the DRBD module loaded in the host. But when I try to attach the resource it says it can't connnect to 'drbd' generic netlink family. Can someone please explain to me what it the 'drbd' generic netlink family even is? And how to get access to it from inside an LXC container? As you can see in my LXCX container's config I have app armor unconfined and no lxc.devices entries so I'm hoping that I've removed as many restrictions that might block access. The following was run from inside the container. root@saucy:~# service drbd status drbd driver loaded OK; device status: version: 8.4.3 (api:1/proto:86-101) srcversion: 5CF35A4122BF8D21CC12AE2 m:res cs ro ds p mounted fstype root@saucy:~# drbdadm attach pc0 Could not connect to 'drbd' generic netlink family Command 'drbdsetup attach 0 /dev/loop1 /dev/loop1 internal --resync-rate=40M' terminated with exit code 20 Here's the container's LXC config. lxc.aa_profile = unconfined lxc.mount = /var/lib/lxc/saucy/fstab lxc.mount.entry = proc proc proc nodev,noexec,nosuid 0 0 lxc.mount.entry = sysfs sys sysfs defaults 0 0 lxc.mount.entry = /sys/fs/fuse/connections sys/fs/fuse/connections none bind,optional 0 0 lxc.mount.entry = /sys/kernel/debug sys/kernel/debug none bind,optional 0 0 lxc.mount.entry = /sys/kernel/security sys/kernel/security none bind,optional 0 0 lxc.mount.entry = /sys/fs/pstore sys/fs/pstore none bind,optional 0 0 lxc.tty = 4 lxc.pts = 1024 lxc.devttydir = lxc lxc.arch = x86_64 lxc.utsname = saucy lxc.network.type = veth lxc.network.flags = up lxc.network.link = lxcbr0 lxc.network.hwaddr = 00:16:3e:f8:ca:e6 lxc.cap.drop = sys_module lxc.cap.drop = mac_admin lxc.cap.drop = mac_override lxc.cap.drop = sys_time lxc.rootfs = /var/lib/lxc/saucy/rootfs lxc.pivotdir = lxc_putold Thanks in advance, Jeremiah
