They're the one serving the loop devices in use. So you exausted the free loop devices. Free one (umount any in use) and try again.
The problem is that there shouldn't be any loop devices in use and there's nothing to unmount. The following transcript demonstrates the problem: [root@localhost ~]# losetup -a [root@localhost ~]# mount -o loop,offset=32256 /usr/local/kvm-images/WinXP.raw /mnt/ [root@localhost ~]# umount /mnt/ [root@localhost ~]# losetup -a /dev/loop0: [080c]:14073859 (/usr/local/kvm-images/WinXP.raw), offset 32256
You can see what is being used by a loop device with losetup: # losetup /dev/loop0 /dev/loop0: [fd06]:234921356 (/linux/isos/backtrack.iso)
Yes, I used losetup to find the culprit (and get rid of it), see my previous mail. man -k can sometimes be very handy :-) Thanks, Andras -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
