Hello, I have not been able to find information about a 'create compressed fs' warning and was hoping someone may point me in the right direction.

My remastering attempts are generating a warning about an incomplete image when I try 'create_compress_fs'. Can this warning be ignored, or does it indicate problem with my remastering approach?

Here is how I am generating the ISO:

Code:
mkisofs -o /home/INNER.remastered.iso  \
                       -hide-rr-moved -cache-inodes 
                       -pad -R -U -V Boot_Disk 
                       -v -allow-multidot 
                       /home/remaster/source/KNOPPIX
The mkisofs is run on a Debian machine. In a successful remastering, I get the following block sizes:

Code:
Done with: The File(s)                             Block(s)    70087
Writing:   Ending Padblock                         Start Block 71979
Sometime (and I can't figure out why), I get different block sizes when trying to remaster the same files. I get the following block sizes when 'create_compressed_fs' exists with the above warning:

Code:
Done with: The File(s)                             Block(s)    70086
Writing:   Ending Padblock                         Start Block 71978
There is a difference of 1 in the above block sizes.


I compress the inner filesystem with the following command:

Code:
create_compressed_fs -v -m -B 65536 \
                                 /home/INNER.remastered.iso \
                                 /home/remaster/master/KNOPPIX/KNOPPIX
The command exits with 1 and produces the following warning:

Writing compressed data..
Does anyone else see this warning message?

Any suggestions on how to debug or fix this intermittent warning?

Thank you,
