Mounted iso filesystem of zs(the 2nd partition) in /mnt/sdb2 mount /dev/sdb2 /mnt/sdb2 2. Made a new iso image using the files that were in the mounted isofs cd /mnt/sdb2 mkisofs -U -r -hide-rr-moved -o /var/tmp/zs_par2.iso ./ Findings: “ls -lh” of the original isoimage(copied using “dd if=/dev/sdb2 of=zspar2_orig.iso“) gives size as 168MB whereas the new image created has a size of 362M without the slightest change. It’s OK if the sizes aren’t the exact same, but the 2nd image is larger than twice the size of the 1st image. I guess I’m missing something . Please help me by pointing out what I’ve missed. Thanks.
