LVM volume group not found (debian lenny)

debian debian-lenny

921

I think I see what the problem is. It appears that your acm_root Volume Group sits on the second RAID array, which is having trouble starting due to this error:

madam: /dev/md0 has been started with 2 drives.
madam:  WARNING  /dev/sdb10 and /dev/sda10 appear to have similar superblocks.

     - if they are really different, please --zero the superblock on one
     - if they are the same, or overlap,\please remove one from the DEVICE list in mdadm.conf.

To fix this, boot into rescue mode once again, and run the following (as suggested):

mdadm --zero-superblock /dev/sda10

Then try booting again. Hope this helps.

I am trying to compile a program in Cygwin and it requires shadow.h in one of the source files, which is missing in the /usr/include path. How do I add shadow support in Cygwin ? any packages to install ?

In CentOS, just installing gcc and glibc provided the shadow.h header file. what are the equivalent packages that I need to install in Cygwin ?

  What does pvdisplay show you? Also, did you create your volume groups on top of your RAID device?

  Could you also provide the output of: fdisk -l This will help determine how the partition layout looks like.

hi vmfarms. it works! may i ask how should i install the system in the future, if you just have a little more time? thank you!

I've looked at the video you sent, and it seems pretty straightforward. It may have been caused by the fact that you have both a Windows and Linux partition on the same drive, and the instructions only account for Linux. In the future to make things easier, I would put Windows on a separate drive entirely. Good Luck!

Is there a workaround for these portability problems for cygwin ? I am using autoconf and make to compile the project.

@sabs6488 i do not have any idea about it.Any workaround will call /usr/lib/shadow and there it won't get support from Gnulib on cygwin for shadow.
