Libguestfs - Feb 2017 - Re: ntfs-3g data deduplication support in guestmount for creating file based back-ups on visualization platform

Thank you Richard!

I will do some more work and testing on this tomorrow, and report back 
with some more information you asked.

In the meanwhile, could you help me with information how I can upgrade 
the ntfs-3g version (same as host) in the "appliance" and add the 
plug-in library?

The plug-in is added manually and is not part of the ntfs-3g (yet), it 
is manually downloaded and copied.

Thank you in advance!

Kind regards,

You can most likely drop a file into /usr/lib/guestfs/supermin.d/
which contains a single line, being the full path of the plugin
file that you want to add.

Actually you can use wildcards there too, so this should work:

  echo '/usr/lib/x86_64-linux-gnu/ntfs-3g/ntfs-plugin-*.so' >
/usr/lib/guestfs/supermin.d/zz-ntfs-plugins

After that, do:

  rm -rf /var/tmp/.guestfs-*

and rerun your libguestfs program (guestmount or whatever).

See "SUPERMIN APPLIANCES" section in the supermin(1) man page for
further information.

Hi Richard,

Is there a way I can access the /var/log/syslog of an running guestmount 
instance to get the grep ntfs-3g /var/log/syslog information?

I managed to get the plug-in to load in my questmount instances by using:

echo '/usr/lib/x86_64-linux-gnu/ntfs-3g/ntfs-plugin-*.so' > 
/usr/lib/guestfs/supermin.d/zz-ntfs-plugins
rm -rf /var/tmp/.guestfs-*

Kind regards,
