help on cloop

[ashivaru]

Hi,

I am using cloop to compress my file system. It has a lot of jar files, binary executables, document files and also shared libraries. I seem to get wierd errors as below. I even tried with various block sizes and I got different error for block size of 128K but, the rest I got the same error

### For block size 64K ###

$ mkisofs -R -U -V "Myfs" -P "ashivaru" \
-hide-rr-moved -cache-inodes -no-bak -pad -relaxed-filenames \
/home/ashivaru | nice -5 \
/usr/bin/create_compressed_fs - 65536 > \
/home/ashivaru/myfs.iso

I am using Redhat 9.1.

Could you please let me know if you have seen such an error before and if I am going wrong somewhere. I really appreciate your help.

cheers,
