In fact, it does. But using lvm2 does not.

I created a vg with on pv and one lv named "test". Then i create ext3
filesystem on it and mount it. Then i try to create a snapshot of this lv:

root at guldukat:~# lvcreate -s -n snap /dev/vol/test  -L 50M
Rounding up size to full physical extent 52.00 MB
device-mapper ioctl cmd 2 failed: Invalid argument
Couldn't load device 'vol-snap'.
Problem reactivating origin test

dmesg says:

device-mapper: ioctl interface mismatch: kernel(1.0.6), user(4.0.0), cmd(0)
device-mapper: ioctl interface mismatch: kernel(1.0.6), user(4.0.0), cmd(0)
device-mapper: internal error adding target to table
device-mapper: ioctl interface mismatch: kernel(1.0.6), user(4.0.0), cmd(0)
device-mapper: ioctl interface mismatch: kernel(1.0.6), user(4.0.0), cmd(0)
kjournald starting.  Commit interval 5 seconds
EXT3 FS on dm-2, internal journal
EXT3-fs: mounted filesystem with ordered data mode.
kjournald starting.  Commit interval 5 seconds
device-mapper: ioctl interface mismatch: kernel(1.0.6), user(4.0.0), cmd(0)
device-mapper: internal error adding target to table

so i guess i have to update the device-mapper in the kernel.

thanks,

Nils
