[linux-lvm] Re: LVM Recovery - mostly solved



Good morning!

Well, this is quite embarassing to me. Bear with me please.

Here we go! That's the point. fdisk -l shows no output because there's
no disk. Between the (doubtless incredibly dumb, but harmless) changes
and the reboot, I have tried to find a place for a spare harddrive in my
chassis. Doing that, the one and only IDE cable loosened. Result:
/dev/hdc was gone.

My focus at that time was of course elsewhere. I always have disabled
IDE scanning in the BIOS, otherwise I would have noticed it immediately
- the system hangs in the BIOS. Linux just says: There's no IDE drive.
And Linux is right.

This comes clear to me now, too. I have to change Grub and/or the
initrd, I guess. I will take a closer look at this this WE.

Of course NOT!

It was trying to read /dev/hdc, but it didn't succeed. How should it?

Well, anyway. I managed to pull down the important data.

List readers/posters: A double sorry to you for wasting your precious
bandwith and for holding you up. I am going to read ALL the docs I can
find on sistina.com about backing up metadata, I promise. And I will
think more than twice next time before posting to this list, and have a
loooong nap before, too.

Thanks to all & a really nice day!
