[linux-lvm] xfs freeze nad snapshot problem

[Piw]

Hello

I got following problem:
Trying to make snapshot of lv with xfs filesystem:
# xfs_freeze -f /data
# lvcreate -L20G --snapshot --name snap /dev/VG/LV

and system lock...

(kill -9 doesnt work)

I have to create another session and remowe lockup with:
# xfs_freeze -u /data

If I try to create snapshot without freezeng xfs, it works (bo no 
cohesion is guaranteed).

kernel: 2.6.9
lvm:	2.00.25
dm:	1.00.19

Anyone can help?
TIA

PS.
