So the failure happens in the call
pivot_root(".", path)
in conf.c:setup_rootfs_pivot_root, with the error message "Invalid
argument". `path' value is "/mnt/lxc/mnt", current directory is
"/mnt/lxc". This seems to be correct, or at least intended. The
directories in /mnt/lxc are mounted as follows:
/dev/mapper/raid10-root on /mnt/lxc type ext4
(rw,relatime,errors=remount-ro,user_xattr,acl,barrier=1,stripe=384,data=ordered)
none on /mnt/lxc/proc type proc (rw,relatime)
none on /mnt/lxc/dev/pts type devpts (rw,relatime,gid=5,mode=620,ptmxmode=000)
none on /mnt/lxc/tmp type tmpfs (rw,relatime,size=16384k)
udev on /mnt/lxc/dev/snd type devtmpfs
(rw,relatime,size=1861084k,nr_inodes=465271,mode=755)
devpts on /mnt/lxc/dev/console type devpts
(rw,nosuid,noexec,relatime,gid=5,mode=620,ptmxmode=000)
devpts on /mnt/lxc/dev/tty1 type devpts
(rw,nosuid,noexec,relatime,gid=5,mode=620,ptmxmode=000)
devpts on /mnt/lxc/dev/tty2 type devpts
(rw,nosuid,noexec,relatime,gid=5,mode=620,ptmxmode=000)
(/dev/mapper/raid10-root is the root file system of the host.)
My container configuration entries are:
lxc.rootfs = /var/lib/vservers/test
lxc.rootfs.mount = /mnt/lxc
And the container fstab:
none /var/lib/vservers/test/proc proc defaults
0 0
none /var/lib/vservers/test/dev/pts devpts gid=5,mode=620
0 0
none /var/lib/vservers/test/tmp tmpfs size=16m,mode=1777
0 0
/dev/snd /var/lib/vservers/test/dev/snd none bind
0 0
I've no idea whether the pivot_root call should succeed or not under
these circumstances. Can you see anything wrong here? Do you need more
information?
