Nobody replied to my last message about the kernel oops and I couldn't
figure it out so I thought I would try upgrading to the latest and
greatest including 2.6.0-test5. I seem to be having some sort of problem
with devmapper not communicating properly with something.
I think I've got the latest everything:
lrwxrwxrwx 1 root root 20 Sep 20 14:35
/lib/libdevmapper.so -> libdevmapper.so.1.00
home:~# lvdisplay --version
LVM version: 2.00.07 (2003-09-16)
Library version: 1.00.05-ioctl-cvs (2003-09-01)
Driver version: 1.0.6
I've got the latest 2.6, the latest devmapper, the latest lvm userland
tools from sistina... But snaps still don't work.
home:~# lvcreate --size 1G --snapshot --name snap /dev/system/tmp
device-mapper ioctl cmd 2 failed: Invalid argument
Couldn't load device 'system-snap'.
Problem reactivating origin tmp
Now I've got an inactive snap lv and an inactive origin lv. I can remove
the snap lv and reactivate the origin lv and everything is fine.
Any ideas what's wrong with my setup?

Firstly, there's some versioning mix-up here, because the driver
in the 2.6 kernels is not 1.0.6.
Secondly, snapshots are not available under 2.6 yet, though the
implementation work is well-advanced.

Actually, if he didn't select the "ioctl interface version 4" option in the
kernel config, it will be version 1.0.6.
Do we think the v4 interface has now gotten enough testing to remove the v1
stuff from 2.6? :)

The next step is submit a patch that makes v4 the default.

Recent tools use a new version of the ioctl interface, only
select this option if you intend using such tools.

Ah, I didn't notice that config option or recognize the implications of
it. No snapshots in 2.6 eh? That's unfortunate. I keep trying to find a
working configuration with which to take snapshots and keep coming up
short. I guess I'll just have to wait a while longer. Thanks for the info!
