LVM2 and Linux 2.6.2

[darren.miller@philips.com]

I am using Slackware 9.0 with Linux Kernel 2.6.2, LVM 2.2.00.08 and device-mapper 1.00.07 create a vg and an lv not a problem all works great.  As soon as I use lvcreate -s etc etc it goes nuts.

Using command: lvcreate -L 28G -s -n snapTue /dev/vault/vol1

gives:   

device-mapper ioctl cmd 9 failed: Invalid argument
Couldn't load device 'vault-snapTue'.
Problem reactivating origin vol1

where it fails to create /dev/mapper/vault-snapTue and link it to /dev/vault/snapTue so I can't do anything with it until I reboot the machine whereby it appears in /dev/mapper but still requires me to manually link it to be removed as once the snapshot create command is run the original volume goes inactive and will not reactivate using lvchange -a -y
I have tried various filesystems for the original to no see difference in behaviour.

So now I am at a loss, do you guys have any clue why this doesn't work where it was working fine with LVM1?

please help..
