[linux-lvm] Shutdown questions

[Adrian Noland]

I'm curious about what happens when the system is shut down (or
crashes) without deactivating LVM. How come you have to "manually"
deactivate it? What kind of recovery attempt is made when this happens.
What kind of problems does this cause when the system comes back up?

You don't have to, I never do. But if you do not deactivate LVM (more
specific the LVs) the lower layer might complain about beeing still
required by LVM and you will not be able to activate it (e.g. LVM over
MD), but I cant say wether this will cause any problems when doing a
normal shutdown.
LVM does not need the deactivation, and there are no recovery attemps
required.

[linux-lvm] lvmcreate_initrd problem

[Adrian Noland]

Hello,
I'm trying to create an initrd and I'm hitting my head against this
error:

lvmcreate_initrd -- ummounting ram disk
umount: /tmp/initrd.2400: not mounted
lvmcreate_initrd -- ERROR umounting /tmp/initrd.2400
                 -- removing /tmp/initrd.2400
                 -- removing /tmp/mnt.2400
rmdir: `/tmp/mnt.2400': Device or resource busy
                 -- removing /tmp/lib.2400
                 -- exit with code 1

How do I find out why /tmp/initrd.$$ isn't mounted? Furthermore, can I
unmount it on my own and complete the script my self? What values would
I use for $DEVRAM and $INITRD?

NB: this isn't a standard install. I'm finishing up a LFS system. This
error only occurs in chroot. Is this a permissions problem or otherwise
related to LFS?

Thanks,
Adrian

The wierd thing is that mount hasn't given an error. I suppose the thing to do
is to stick a "pause" or an "exit" after the mount to see if has actually worked
(if not, then strace it and see why not). If it has worked then figure out why
it get umounted in between or if the variable named gets mangled for any reason.
