From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; H010818) Description of problem: After the Red Hat 2.1 AS QU3 installation on a Bladecenter was completed, the following text was displayed on the screen. The blade never rebooted on its own after the install. Ummouting filesystem.... /mnt/runtime done disabling /dev/loopo /proc/bus/usb done /proc done /dev/pts dome /mnt/sysimage/boot done /mnt//sysimage/proc/bus/usb done /mnt/sysimage done /mnt/source Apparently this occurs while any USB based filesystems are mounted; an endless loop waiting for the filesystem to respond to the unmount command. Unable to reproduce with RHL 9. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Install AS 2.1 Update 3 on system using USB CDROM such as Bladecenter Actual Results: Requires manual hardware reset. Expected Results: System reboots.
At that point, everything looks unmounted -- /mnt/source should be the last one that gets unmounted. Did this happen with U2? What are the USB filesystems being mounted for?
Yes this was reproduced with U2. The USB CD-ROM is mounted for the installation and does appear to be unmounted. However, the system does not reboot.
Can you switch ttys at this point? If so, is there anything odd on tty4? Can you get the output of Alt+SysRq+T?
Looks like it's not an anaconda bug since a similar hang can be reproduced post-install. 1. Mount USB CD-ROM 2. Attempt to reboot by executing init 6 3. Server will stop at "Unmounting filesystems" message. Manual reset of the server is required.
ok not a regression "just" a normal bug
Has anyone at Red Hat been able to reproduce this on a blade? I did find a possible workaround: At the end of the installtion, at the "Finished" screen, I switched to tty2 and ran "umount /mnt/source". I switched back to the GUI screen, and clicked "Finished". System did not reboot and last message seen was "Ejecting /tmp/cdrom" I reinstalled and this time I ran these commands at the "Finished" Screen: umount /mnt/source rm /tmp/cdrom System did reboot, but CD was left in the CDROM.
fixed in u5 beta.
