[linux-lvm] odd problem

[linux-lvm] odd problem

[Todd Underwood]

folx,

i have 2.4.3 with beta-7 patches installed and beta-7 userland tools.  i'm
using lvm-initrd with a boot partition on /dev/hda2 and LVM root and other
filesystems on a few scsi disks.  all was working well but recently i
needed to reboot (i was unable to increase the size of my / with the
online ext2 tools and it was full--not sure what the error was there, or
whether that is relevant).

in any case, now i reboot and i get
lvm -- lvm_chr_ioctl:  unknown command 4004fe0a
vgchange -- volume group "rootvg" successfully activated

VGS: Mounted root (ext2 filesystem) readonly.
change_root: old root has d_count=3
Trying to unmount old root ... <7>uhci.c: suspect_hd
okay

a bunch of other stuff

then:

Activating swap partitions swapon: /dev/rootvg/swap: Invalid argument
Setting hostname zapata.staff.osogrande.net execvp: No such file or
directory

/etc/rc.d/rc.sysinit:  domainname: command not found

and so on.  looks like nothing's mounted.  the same kernel boots fine with
an older root fs on a 'real' partition.

any suggestions?

It sounds like the kernel patch revision doesn't match the revision of 
the user-level tools - I saw these types of messages when running beta-7 
tools with a stock 2.4.3 kernel.  Have you made sure the tools/libraries 
on your initrd image are up to date?

howdy,

i'm almost positive (i know... famous last words) that they are up to
date, because the same kernel boots with a different root. 

i lost some files in /etc/ due to stupidity and had to restore them (the
wonders of ext2 file undeletion by hand!) but i ran vgck to check volumes
and it seems fine.  i even copied all of /etc/ over from the working linux
root partition to the non-working logical volume and that didn't seem to
help.  i've run fsck on it to no avail.  

happy to provide addl info.  i'm going to double check that the patches
are on the kernel and the kernel is recompiled and the initrd is right and
the user tools are right.

Probably not relevant, but it is of interest to me what sort of problems
you had.  I assume you have patched the kernel with the online ext2
kernel patches and also enabled CONFIG_EXT2_RESIZE?  You should not have
any problems resizing root.

Expected behaviour with new tools (compatibility reasons).  However, it
_does_ indicate that you do not have beta7 LVM kernel code.

Don't know about this.

Hmm...

Do you run "vgchange -a y" (and optionally vgscan) in startup scripts?
There is a "LVM root howto" somewhere on the Sistina site.

Is he using a USB storage device?  Isn't uhci.c part of the USB subsys?

andreas, folx,

thanks for the replies and suggestions.  comments below...

i am using the kernel patch and have CONFIG_EXT2_RESIZE.  i have had
problems with resizing when i resize several filesystems repeatedly by
small amounts (that is always my preference, rather than giving one big
boost that may waste space).  at the time i had difficulties the root was
full (except for space reserved for root), but i don't know if that is
relevant.  unfortunately, i've got no specifics to report, but i'll try to
reproduce it today.

interesting.  i will recompile, recompile, re-lilo and try again.  this
really *was* working with that kernel before. sigh.  this is helpful to
know, though.

yes.  i put vgchange -a y and vgscan in /etc/rc.sysinit (it's a RH box)
and that seems to be working well for now without the LVM root, but given
the problems i've had with /etc, i will recheck the faq and try again.

again, thanks for the help.
