I manually mounted it, so it was not listed in /etc/fstab... Smilie

I had kind of hoped to resolve this without a reboot... Thanks anyway.
Try umount -f to force the unmount of the now dead ISO image or try to umount by the mounted sub-dir name:

Code:
umount /mnt/some_iso_image_of_redhat

umount.nfs

UMOUNT.NFS(8)						      System Manager's Manual						     UMOUNT.NFS(8)

NAME

       umount.nfs, umount.nfs4 - unmount a Network File System

SYNOPSIS

       umount.nfs dir [-fvnrlh ]

DESCRIPTION

       umount.nfs and umount.nfs4 are a part of nfs(5) utilities package, which provides NFS client functionality.

       umount.nfs4  and  umount.nfs are meant to be used by the umount(8) command for unmounting NFS shares. This subcommand, however, can also be
       used as a standalone command with limited functionality.

       dir is the directory on which the file system is mounted.

OPTIONS

       -f     Force unmount the file system in case of unreachable NFS system.

       -v     Be verbose.

       -n     Do not update /etc/mtab.	By default, an entry is created in /etc/mtab for every mounted file system. Use this option to skip delet-
	      ing an entry.

       -r     In case unmounting fails, try to mount read-only.

       -l     Lazy unmount. Detach the file system from the file system hierarchy now, and cleanup all references to the file system as soon as it
	      is not busy anymore.

       -h     Print help message.

NOTE

       For further information please refer nfs(5) and umount(8) manual pages.

FILES

       /etc/fstab	 file system table

       /etc/mtab	 table of mounted file systems
