[lxc-users] Setting up containers with multiple logical volumes

[Joshua Schaeffer]

Yes it failed to start:

1. lxc-create -n testme1 -t debian
2. root at reaver:~# cat /var/lib/lxc/testme1/config | grep lxc.mount.entry
     lxc.mount.entry = proc proc proc nodev,noexec,nosuid 0 0
     lxc.mount.entry = sysfs sys sysfs defaults  0 0
     lxc.mount.entry = /dev/vg_lxc1/lv_ldap_tmp1 lv_ldap 
defaults,create=dir 0 0
3. root at reaver:~# lxc-start -n testme1 -l trace -o testme1.out
     lxc-start: No such file or directory - failed to mount 
'/dev/vg_lxc1/lv_ldap_tmp1' on '/usr/lib/x86_64-linux-gnu/lxc/lv_ldap'
     lxc-start: failed to setup the mount entries for 'testme1'
     lxc-start: failed to setup the container
     lxc-start: invalid sequence number 1. expected 2
     lxc-start: failed to spawn 'testme1'

Thanks,
Josh
