#77 Restore from lzip fails.

[Scaz]

When trying to restore from an lzip image, Clonezilla fails to detect the filetype and bails out with "Unknown format for /home/partimag/path/sda1.ntfs-img.aa!!! Program terminated!"

This seems to be similar to the problem with uncompressed NTFS backups which was fixed (https://sourceforge.net/mailarchive/message.php?msg_name=021101c70949%2487126220%24690aa8c0%40ATGIS05)

The /opt/drbl/sbin/ocs-functions script uses two ways to detect the compression used; filename/extension and the 'file' command. Clonezilla live doesn't save images with the expected extension/filename and I don't think lzip is in the 'file' command based detection. I worked round this by simply copying the 'if' statement from the 'case' statement that detects lzip by filename and putting it after the first detection routine ends.

This occured in clonezilla-live-1.2.5-30-i686.iso and clonezilla-live-1.2.5-17-i686.iso, both Ubuntu and Debian. The target was NTFS (Win XP SP3) cloning a whole disk via parallel lzip.

Other than this glitch, nice program. Really, very nice.

Could you provide a patch file? It's easier for us to modify that.
Thanks.

Sorry Steven, I'm no programmer. Only know enough to stumble through others' code. Shall have a look and get the line numbers for you at least. As I say, I think it's just that the lzip detection in the second (file command based) routine's been missed out rather than it not working. I'll double check when I've got the chance and update as best I can.

Thanks.

Or you can email me the file you modified? If so, please email me at <steven _at_ nchc org tw>
Thanks.

Added lzip detection to 'file' metod and works for me, patch based on clonezilla-live-20100729-maverick.

Thanks for the patch file.
One thing I do not understand is, by default clonezilla should save the lzip image as:
-rw------- 1 root root 146M 2010-08-11 20:30 sda1.ext4-ptcl-img.lzip.aa
The first method in ocs-functions should work...
Could you please show me your image file content by:
find /home/partimag/$YOUR_IMAGE/ -print
(Replace $YOUR_IMAGE with your image dir name).
Thanks.

Steven.

Committed in the CVS repository. It will be included in the next release of Clonezilla live.
Thanks.
