Zero the superblock

Mark_in_Hollywood · 04-12-2006, 04:29 PM

I received a "letter" at boot from root@localhost.

It said that I MUST (emphasis theirs)

zero the superblock before activating the autostart feature.

and

Do not start RAID devices automatically.

mdadm--zero-superblock /dev/xxx

and

dpkg-reconfigure mdadm

Please tell me if /dev/xxx would be /dev/hda OR /dev/hd0

also, tell me what has happened to my newly minted Ubuntu/Breezy Badger after 10 hours of downloads, if you know.

Do I need to be online when I run dpkg? Would it be better if I were?

I didn't see any info that I had started the RAID automatically. Heck! I've only got a used 40gig hdd, anyway!

I checked the other thread at this forum on Superblock but while similar, there aren't comparable. Hence this post.

Don't you think it's a spam, or a joke? Check the body of the mail to find some IP.

Umm, no---he's getting system mail from his own system.

OP;
I infer you have a RAID setup. Was it working once? Do you know if you changed something before this behavior started?

OMG, who is your root?!?!?!?!
THis is kinda awkward, why zero the superblock before autostart?

Response 1. Don't you think it's a spam, or a joke?

It's from the system!

Response 2. I infer you have a RAID setup

This is an install that started with Hoary Hedgehog ver. 5.04. on CD. I then proceeded to update/upgrade via Synpatic/Update Managers, online. If RAID is setup, I didn't ask for and don't want it.

Response 3. OMG, who is your root?!?!?!?! This is kinda awkward, why zero the superblock before autostart?

I am the only user of this computer. I SUDO when / work must be done. Otherwise I don't mess with this system. By / work, I mean: anything that requires SUDO. I "installed" a script from Ubuntu.com about changing the wallpaper. That ALL. I have used Automatix and Synaptic/Update managers. THAT'S IT. There ain't no more. I've been using Ubuntu since early March 2006 and don't know my / from a hole in the ground.
