I'm using ubuntu 9.10 with kernel 2.6.31. In addition to the boot disk, I have a software raid of 5 disks using mdadm. One disk failed. I removed it from the array. mdadm --detail /dev/md0 shows:

0       8       17        0      active sync   /dev/sdb1
1       8       33        1      active sync   /dev/sdc1
2       8       49        2      active sync   /dev/sdd1
3       0        0        3      removed
4       8       81        4      active sync   /dev/sdf1

I installed a new disk in /dev/sde, but after I format it, I can't get the device /dev/sde1 to exist.

Then I reboot for good measure. After:

enter image description here

  • I've tried fdisk, parted, and gparted. I get the same behavior after formatting in all programs.
  • The partition is not listed in /proc/partitions
  • There are no strange messages in /var/log/messages
  • All drives are listed in BIOS, including SDE
  • My dmesg output is available here: http://pastebin.com/BX6ya3qx

I'd add the /dev/sde1 manually with MAKEDEV, but this uses udev, so I don't know what to do. How do I get the /dev/sde1 device to appear?

Thanks for your help Journeyman Geek. I realized I'm actually using Ubuntu-9.10. I'll edit my question once I have 10 rep. –  dereferenced Apr 30 '11 at 14:07

I upgraded to Ubuntu 10.04 LTS and it magically started working. I can only assume it is a kernel or distribution issue.
