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" \

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,
