[linux-lvm] LVM and devfs

[-- Attachment #1: Type: TEXT/PLAIN, Size: 349 bytes --]

Hello all,

I have a few errros on boot that are generated by devfs, as much as I can
figure.  it doesn't like the fact that LVM creates devices or something.  I
have attacked a small file that contains the errors.  Everything *works*
fine, but I still don't like seeing errors spewed on bootup.  Any help
woudl be greatly appreciated. TIA!

Which LVM version are you using?

The recent 0.9.1 Beta 5 shouldn't give you that error.

[linux-lvm] LVM and devfs

[Stuart Felenstein]

[-- Attachment #1: Type: text/plain, Size: 1137 bytes --]

I didn't see a search option in the archives and I apologize if this is more appropriate to the devfs list.  I installed RedHat9 , and partitioned with DiskDruid using LVM.  The only partition that is not LVM is /boot.
However I have now compiled kernel 2.4.23 with LVM and devfs and running into a problem with kernel panics.  I'm not sure if having LVM is causing the issue.  Even though I've tried many different append roots, looking at the working kernel in lilo.conf I see root = /dev/Volume00/LogVol01.  So I'm' wondering how I translate that to /dev/ide/host0..... .
 
Here is my current /etc/fstab: 
/dev/Volume00/LogVol01           /                       ext3
LABEL =/boot                          /boot                 ext3
/dev/Volume00/LogVol02           /cache              ext3
/dev/Volume00/LogVol03           /myth                ext3
none                                       /proc                  proc
none                                       /dev/shm            tmpfs
/dev/Volume00/LogVol00          /swap                 swap
/dev/cdrom

Greatly appreciate some help, pointers and / or links.
Thank you,
Stuart

Re: [linux-lvm] LVM and devfs

I believe your problem is that you need an initrd that includes LVM
stuff. Try the command "lvmcreate_initrd", then ensure that the new
lvm_initrd file is loaded with lilo (I use grub so I can't help you with
lilo). RH uses their own initrd, so you should be able to use the
existing lilo.conf as a guide. If you have an unusual setup you may have
to mount the initrd file, and edit it yourself.

Thank you.  I solved part of my problem by getting the devfs daemon loaded. Now working through the rest of the doc.  I realized after some time that LVM can coexist with devfs and they are not going to bump heads.

- devfs in not supported on redhat 9
- lvm created on a non devfs system do not work on a devfs system
  without tinkering and vice versa. devfs=nomount yelds even worse
  results
  remove devfs from your kernel

Luca, 
 
I think you may be off here.  It was RedHat9 that gave me the option of using LVM.  
I've gone to the 2.4.23 kernel with devfs and lvm support.  I know there is alot or a good amount of controvery around devfs but I think I'll ride it out and see how it works for me.
Thank you for your response.

i said _devfs_ is not supported,
_lvm_ is.

lvm1 tools do have a problem with switching from devfs to non-devfs,
and vice-versa since they use /proc/partitions to find pvs, and do write
the pv name in the metadata. (read the list archives for the gory
details)

I have looked for this info, and haven't foud a conclusive answer. Is 
there a recipe (no matter how convoluted) for migrating from a devfs+lvm 
system to a non-devfs lvm system?

I use lvm1+devfs on a few (Gentoo, 2.4.23) systems and I had no problems
so far. I even switched the drives around, e.g. making primary master
secondary slave and so on, and to my suprise it just worked as if I
didn't do anything. So I don't understand why there are troubles moving
from lvm1 with devfs to lvm without devfs. I even used KNOPPIX in one of
the systems, which has devfs disabled AFAIK, and still had no problems
getting access on my data besides doing manual "vgscan ; vgchange -a
y" and mounting.

Just my 0,02 Euro.
