Hi,<br>
<br>
I have the same problem with a converted CT.<br>
I converted from simfs to ploop using<br>
<br>
vzctl convert <CTID> --layout ploop<br>
<br>
After conversion I started the CT and tried to resize:<br>
<br>
vzctl set <CTID> --diskspace 75G --save<br>
Can't ioctl mount_point: No such file or directory<br>
Failed to resize image: Can't ioctl mount_point: No such file or directory [3]<br>
CT configuration saved to /etc/vz/conf/<CTID>.conf<br>
</blockquote>
<br></div>
First of all, I would like to have such reports as bugs in <a href="http://bugzilla.openvz.org" target="_blank">bugzilla.openvz.org</a> rather than emails to users@. Bugzilla is specifically designed to track bugs, while on a mailing list it could easily be lost.<br>
<br>
Now, can I ask you to debug this for me (since I am unable to reproduce it).<br>
<br>
1. If you happen to have vzctl convert output, please show it. I am especially interested in the line mentioning balloon.<br>
<br>
2. Can I see the line in /proc/mounts regarding this mount? it can be obtained by e.g.<br>
cat /proc/mounts | grep -w <CTID> | grep ploop<br>
<br>
Provided this, I will ask for more later.<br>
