Yes, it's listed in both the VE and the node.
To summarize your hypothesis this is what presumably happens:
- The mount script running in the node's context mounts the drive and writes the record to the mtab of the node.
- When the VE is brought down, the init scripts unmount the drive in VE context, since it appears in /proc/mounts = /etc/mtab of the VE.
- When the unmount script in node context is run, the drive is already unmounted and umount fails, so the record stays in the mtab of the node.
What I still do not understand, is why all stale entries in the node's mtab disappear, when I manually unmount the drive while the VE is down. Can anyone imagine, what's the difference in the unmount script context and a root shell with the VE stopped?
