As a sanity check, can I get you to try extracting either the i686 or x86_64 images instead of the ppc64 one? Thanks! Kyle
# file /mnt/archive/fedora/development/16/x86_64/os/isolinux/initrd.img /mnt/archive/fedora/development/16/x86_64/os/isolinux/initrd.img: XZ compressed data # xzcat /mnt/archive/fedora/development/16/x86_64/os/isolinux/initrd.img > initrd xzcat: /mnt/archive/fedora/development/16/x86_64/os/isolinux/initrd.img: Compressed data is corrupt
look like that was an invalid test, initrd.img is a concat of images. xzcat can't handle that. What I'm currently doing to test this issue is to pack enough files into a xz compressed squashfs image, mount that via loopback and then cat each file in it to /dev/null. Some of them will fail with the I/O error mentioned above: # mksquashfs /usr squashfs.img -comp xz -Xbjc powerpc # mkdir mnt # mount -o loop squashfs.img mnt # find mnt/ -type f -print -exec cat {} >/dev/null \; It takes a while, but then you'll get the error and squashfs errors get logged in syslog.
