[linux-lvm] lvm -- lvm_chr_ioctl: unknown command 0x8004fe97

[Jon Bendtsen]

Since i want to run with ext3 and use snapshots, i applied the 
	linux-2.4.18-VFS-lock.patch
to my default 2.4.18 kernel. I just did that file since making
the patches, and applying that would fail during compilation.
(something about md driver ?, which i dont use)

So, after just getting the VFS-lock patch to work, i've tried
to use it on my debian woody, with 
	lvm-common     1.5.5
	lvm10          1.0.4-4
installed. But i get alot of errors :/
	lvm -- lvm_chr_ioctl: unknown command 0x8004fe97
	lvm -- lvm_chr_ioctl: unknown command 0x8004fe97
	lvm -- lvm_chr_ioctl: unknown command 0x8004fe97
	lvm -- lvm_chr_ioctl: unknown command 0x8004fe97

And sometimes vgscan cant find my VG, and i cant activate it with
	vgchange -a y ...


It _MIGHT_ be because i'm running lvm ontop of a loop-AES, but it does
work most of the time.

ps: right now i'm starting all over with 
	2.4.19
	lvm_1.1-rc2.tar.gz
and removing those debian packages.

You really don't want to do that... 1.1 is well broken.

The Debian packages should be fine. Plenty of other people are using them.

Can you tell which command is issued the illegal ioctl ? It could be that the
LVM device has a wrong major/minor or something else has take the LVM
major/minor device number, because those are /not/ LVM ioctl numbers.

If you can determine what command is issuing those odd ioctls then you're
probably half-way to finding the culprit.

uhoh, i'm already doing it, not production yet, but soon.
I figured that the latest from oktober 3, 1.1-rc2 would be
good enough.

More than one. vgchange -a y <VG>
lvremove (snapshopts)

Well, it's not just one command.

It does sound a lot like an "odd" lvm toolset (or perhaps library) that's
interfering. It's worth checking whicg vgchange (etc) command is being run (ie
is there one in /usr/local or /usr/sbin that's earlier in the PATH than the
"real" one. Also do "ldd" in the library to see which library is being picked
up.

i think it was the debian packages, because it stopped after removing
the
debian packages and make;make install
the lvm-1.1-rc2

Seems unlikely - I'm the maintainer of the Debian packages and I can state
categorically that they don't issue that ioctl :-)

well, it works now. I did try with another lvm 1.1-rc? maybe thats why?

Could easily be. My guess is that the Debian symlinks got overwritten with
something else so the actual Debian ones (which live in /lib/lvm-10) were not
being called at all.
