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?
