depending on your hardware, you can boot from a livecd and fsck troublesome partitions. <div>On 8/28/07, Howard, Chris <<a href="mailto:HowardC@prpa.org"> HowardC@prpa.org</a>> wrote:<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> If you have the time and inclination, I'd run fsck on all of them, or at least all of the partitions on drive /dev/sda -----Original Message----- From: <a href="mailto:rhn-users-bounces@redhat.com">rhn-users-bounces@redhat.com</a> [mailto:<a href="mailto:rhn-users-bounces@redhat.com"> rhn-users-bounces@redhat.com</a>] On Behalf Of Paula J.

Thank you Chris and Mark. Yes, these are scsi drives and when I did a df and then tried to umount /dev/sda5 so that I could do fsck to the drive, it tells me drive is busy. It shouldn't be, I rebooted, everyone's off, I looked at mount, nobody's mounted, but it still won't let me umount. I'm thinking about going over to the building where the machine is and booting from the dvd and then trying to umount. This worked on another system a while back. Any more suggestions/advice is very very much appreciated.
