"WARNING: got more data then expected" when trying "create_compressed_fs"
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,
Jon
