HELP!! N1A1DD1: not automatically assembling /dev/md2

Post by pdario » Tue Sep 30, 2014 1:46 pm

Hello, please help!

I must have messed something with my NAS and now it does not assemble /dev/md2 at boot.

I added mdadm-raid into runleve.conf and added /mnt/disk/vaolume1 in fstab, but this is not the way it's meant to be and several pieces of the software does not start properly (web admin unaccessible, can't be turned off with power button...).

I looked here and there, even comparing with an old tar backup I have and didn't find anything significant changed.

In /var/log/kern.log I see:

Sep 28 20:53:27 LG-NAS kernel: [ 1.515627] md: Waiting for all devices to be available before autodetect
Sep 28 20:53:27 LG-NAS kernel: [ 1.522461] md: If you don't use raid, use raid=noautodetect
Sep 28 20:53:27 LG-NAS kernel: [ 1.528890] md: Autodetecting RAID arrays.
Sep 28 20:53:27 LG-NAS kernel: [ 1.575817] md: invalid raid superblock magic on sda3
Sep 28 20:53:27 LG-NAS kernel: [ 1.580909] md: sda3 does not have a valid v0.90 superblock, not importing!
Sep 28 20:53:27 LG-NAS kernel: [ 1.587915] md: Scanned 3 and added 2 devices.

but that was the same in the working backup, too.

Even with the modifications I made, /var/log/platformd.log

2014-09-28 20:52:15,049 INFO [SYSTEM] : Start platform daemon boot-up sequence
2014-09-28 20:52:15,605 DEBUG [VOLUME] : there is no online volume on boot-up time

instead of

2014-07-11 20:09:24,007 INFO [SYSTEM] : Start platform daemon boot-up sequence
2014-07-11 20:09:25,218 DEBUG [VOLUME] : /dev/md2 assemble done
2014-07-11 20:09:26,792 DEBUG [HOT_SWAP] : HDD1 is online

even if I added mdadm-raid before platformd in the runleve.conf.

Can anybody assist me in finding what's wrong?

BTW, root@LG-NAS:~# cat /etc/mdadm/mdadm.conf

Code: Select all

# mdadm.conf
#
# Please refer to mdadm.conf(5) for information about this file.
#

# by default, scan all partitions (/proc/partitions) for MD superblocks.
# alternatively, specify devices to scan, using wildcards if desired.

I have had the same with another LG nas, cannot remember the type anymore. An el-cheapo 2 disk nas. I added a startscript for sshd, or something like that. Somehow the fimrware detects that, and refuses to boot anymore. I was not able to solve that problem.
In the end I just installed Debian on that box. Problem solved.

I'm not at that stage yet!! ;)

For now, I would only like to restore md2 auto-assembling as before.

And it already has Debian onboard.

In case I give up, I'll bug you to know how to install a new Debian on it.

Thank you
