I received this message when doing an upgrade from RC1 to RC2. I believe this is after the packages installed, but I'm not 100% sure as I walked away from the computer while the install ran. Exception Occurred <boilerplate> Traceback(innermost last): File "/usr/bin/anaconda", line 507, in ? intf.run(todo, test = test) File "/var/tmp/anaconda-7.1//usr/lib/anaconda/text.py", line 1216, in run rc = apply (step[1](). step[2]) File "/var/tmp/anaconda-7.1//usr/lib/anaconda/text.py", line 643, in __call__ in todo.doInstall (): File "/var/tmp/anaconda-7.1//usr/lib/anaconda/todo.py", line 1749, in doinstall (p, self.inft.messageWindow, pkgTimer)) File "/var/tmp/anaconda-7.1//usr/lib/anaconda/todo.py", line 1748, in instCallback fn = self.method.getFilename(h, pkgTime) File "/var/tmp/anaconda-7.1//usr/lib/anaconda/image.py", line 87, in getFilename isys.umount("/mnt/source") File "/mnt/redhat/test/qa0302.0/i386/RedHat/instimage/usr/lib/anaconda/isys.py", line 123, in umount rc = _isys.umount(what) SystemError: (16, 'Device or resource busy') Looking at this further, I suspect it was trying to eject the cdrom so that it could use the second disk.
Were you using tty2 and poking around in a directory under /mnt/source?
Hmm, yes, I was. I needed a way to figure out what version of RH I was installing, since the splash screen (lilo text, I guess) said 7.0.91, but I'd labeled these CDs are RC2 (7.0.93). Turns out the splash screen was wrong. I guess I should file that as another bug.
