[linux-lvm] Upgrade Linux 2.2 to 2.4 problems

[linux-lvm] Upgrade Linux 2.2 to 2.4 problems

[Dick Middleton]

I'm still having difficulty getting LVM to behave itself on a 2.4 kernel 
when it
works fine on a 2.2 kernel.  I'm using beta7 on both kernels - the 2.4 
kernel
is 2.4.10.ac4 which seems to have version beta7(ish) in it.  I'm booting 
through
initrd as /root is on LVM.

vgscan appears to work ok but vgchange fails with:

Error- can't get names of physical volumes - please check if /proc is 
mounted.

Well, /proc is mounted - in fact if it isn't mounted I don't this error.

What does this error message mean and what's likely to be wrong to cause it?

Many thanks

Dick

Dick,

this can't be the exact LVM 0.9-Beta7 error message.
Is /proc really mounted, *before* vgchange runs in /linuxrc?

BTW: why do you use such an old kernel and LVM version?
     Please give a recent one and LVM 1.0.5 a try.

  Heinz,

It sure is (except error is written ERROR and the message is on 2 lines 
:-) )

Hmm - I'm not sure how I can tell.  The mount command certainly comes first
and there are no visible error messages.  I'm just using 
lvmcreate_initrd. If the
mount command fails then it gives an error message and vgchange gives me
different error messages so I assume it's working.

That's what I was trying to do (for a while)  until I discovered this 
kernel only has beta7 in it.

Curiously I had more success with 1.0.5 tools on this kernel.   

I think I'll take your advice and start again.

Many thanks for your support.
