NFS install from a loop-back mounted DVD image fails for me when it actually tries to start the RPM install process. I come to the point where anaconda checks the package dependencies, then it tells that the install process will be started in some minutes and the last thing I see is a message similar to: Preparing transaction from install media. Then this message box disappears and the install process is stalled. On text console #4 I see these two last lines: <5>SQUASHFS error: sb_bread failed reading block 0xb085 <5>SQUASHFS error: Unable to read page block 2c11bde, size fbb7 This happens on a x86_64 install, but I get a similar message when I try to install a i386 Centos5. Both DVD images were downloaded using Bittorrent and the sha1sums and md5sums are all correct. The NFS server is RHES4.4 i386. Any ideas how to fix this problem? Best regards, Bernd.
