[linux-lvm] I've tried to get some support on this list about lvm



but I've had no responses.
I'm sure I've discovered a bug but nobody has answered my 
question of offered any advice or requested any further 
information.
Please look at my problem and see if there is anything which might 
help me.

I'll post it here too so that if for some reason you can't access the 
forum:

 device-mapper: reload ioctl failed: Invalid argument Failed to 
suspend LogVol00
I hope this is the right forum.
I've read hundreds of threads on this problem but they seem to be 
intermittent and the resolution has been using a different kernel 
version.
I'm using the latest kernel but I still have this problem
[root fc11-64 ~]# rpm -q kernel

Running Logical Volume Manager gui and attempting to extend the 
volume results in the same error.
