My understanding is like yours. Basically, you are running a live CD, completely independent of the installed system. What does cat /etc/mtab show? If /dev/sda2 is being held by some process in the rescue OS that is accessing it, it should show up as an active partition in the mtab. What happens if you do umount /mnt/sysimage ? Does the cat /etc/mtab command show anything different? Do you have more than one disk? Is it possible that the rescue CD is ordering them differently than you think, and what it is calling /dev/sda is actually /dev/sdb? Better to use block IDs to identify disks these days. The command /sbin/blkid will show them to you. -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
