I have also experienced the 'The kernel was unable to re-read the partition table on /dev/md0' issue.
Using Debian 5.0.1 AMD64 installation CD. I want to have RAID1+LVM. As GRUB won't boot from LVM I thus want '/' to be RAID1, all other partitions to be RAID1+LVM. I use the graphical installer to create two RAID1 partitions. Then I choose to configure LVM -> save changes to disk before doing so -> "Warning! The kernel was unable to re-read the partition table on /dev/md0 (Invalid argument). This means Linux won't know anything about the modifications you made until you reboot. You should reboot your computer before doing anything with /dev/md0". I'm allowed to continue, to I setup each LVM volume and afterward get a screen that just says: "Partition disks ??? 0 ???". I'm able to choose Continue and then get a screen that just has a title saying "Partition disks" and is otherwise blank, no buttons. In the terminal window displaying error messages, the last is "debconf: cdebconf_gtk (process:5384): kdk-DirectFB - WARNING: gdk_display_requelection_notification Unimplemented function". I reboot and go back to the partitioning option where I am able to again setup the LVM volumes. Everything now seems OK. Is this system safe to continue deploying? or does some issue lurk that could bite in future? -- Pete Boyd Open Plan IT - http://openplanit.co.uk The Golden Ear - http://thegoldenear.org -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
