Bernard, So you have 16 loopback devices. But I see the error: > mount: could not find any free loop device
So I wonder how many of the 16 are available for use. What does "mount | grep loop" return? (I'm not sure of another way of telling which loopback devices are being used). Here's an example: # mount | grep loop /nfs/rhel5.2/RHEL5.2-Server-20080430.0-s390x-DVD.iso on /nfs/rhel5.2/dvd type iso9660 (ro,loop=/dev/loop0) /nfs/sles10sp2/SLES-10-SP2-s390x-GMC-DVD1.iso on /nfs/sles10sp2/CD1 type iso9660 (rw,loop=/dev/loop1) /nfs/rhel5/RHEL5-Server-20070417.0-s390x-DVD.iso on /nfs/rhel5/dvd type iso9660 (ro,loop=/dev/loop2) /nfs/sles10sp1/SLES10-SP1-DVD-s390x-RC5-DVD1.iso on /nfs/sles10sp1/dvd type iso9660 (ro,loop=/dev/loop3) /nfs/sles10sp2/SLES-10-SP2-s390x-GMC-DVD1.iso on /nfs/sles10sp2/dvd1 type iso9660 (ro,loop=/dev/loop4) Another thought would be to preface the mksles9root.sh command with "sh -x" and see if that gives any more hints.
