bind mounts don't work? [message #38274]

Hello!

I'm using Debian with kernel 2.6.26-2-openvz-686
mounting part of HW-node into container (/vz/private/NR/home/SPACE) doesn't show data inside the container. Outside it works (all data visible)
What can I do?

thanks,
Andrew

Describe the situation in greater details. How you do the mount (what, to where), how you check etc.

start VE then try mount to "/vz/root/NR/home/SPACE", instead of "/vz/private/NR/home/SPACE"

Right,
(1) you need to mount to /vz/root not /vz/private
(2) you need to do 'vzctl mount' before that
(3) you can automate it using vzctl mount scripts

Hi!
How can I dump(checkpoint) if external mounts there (mounted, because locked)?
vz:
ctl --ckpoint 120
dump 120
ctl destroy 120
dump --restore 120
ctl restore 120
# restore 120 says: "Error: undump failed: No such file or dir
# Error: mount point is missing: /home/SPACE. Stopping, Unmounting"

ctl mount (for allowing bind-mounts to root)
mount --bind ... .../root/120/home/SPACE
leads to same error msg

thanks, Andrew
