Public bug reported: Binary package hint: mdadm
I've had this problem happen a few times in the past with previous versions of Ubuntu. (I'm now on Lucid) I forget how I got rid of it then. What happened now is a just added a couple of eSATA disks (/dev/sdd and /dev/sde) (they function like regular SATA disks.) I had setup my /dev/md0 array from /dev/sdb and /dev/sdc months ago. Now all of a sudden it fabricates a /dev/md_d0 array somehow (based on /dev/md0p1) and the system fails to mount /dev/md0p1. This is the output from cat /proc/mdstat: m...@hegemon:~$ cat /proc/mdstat Personalities : [linear] [raid1] [multipath] [raid0] [raid6] [raid5] [raid4] [raid10] md_d0 : inactive md0p1[1](S) 245111616 blocks md0 : active raid1 sdc[1] sdb[0] 245117312 blocks [2/2] [UU] unused devices: <none> My workaround for now is to manually remove /md_d0 every time I reboot the system as follows: m...@hegemon:~$ sudo mdadm --manage --stop /dev/md_d0 mdadm: stopped /dev/md_d0 I can then run mount -a and it successfully mounts /dev/md0p1 I get this output after deleting the array, I believe it is the same as before I delete it: m...@hegemon:~$ sudo ls /dev/md* /dev/md0 /dev/md_d0 /dev/md_d0p2 /dev/md_d0p4 /dev/md0p1 /dev/md_d0p1 /dev/md_d0p3 /dev/md: d0 d0p1 d0p2 d0p3 d0p4 ProblemType: Bug DistroRelease: Ubuntu 10.04 Package: mdadm 2.6.7.1-1ubuntu15 ProcVersionSignature: Ubuntu 2.6.32-24.39-generic 2.6.32.15+drm33.5 Uname: Linux 2.6.32-24-generic x86_64 Architecture: amd64 Date: Sun Aug 8 21:05:33 2010 InstallationMedia: Ubuntu 10.04 LTS "Lucid Lynx" - Release amd64 (20100429) MDadmExamine.dev.sda: Error: command ['/sbin/mdadm', '-E', '/dev/sda'] failed with exit code 1: mdadm: No md superblock detected on /dev/sda.
