[Fedora-xen] newbie question to increase the size of "guest OS"...

[Dharmesh Kamdar]

Hi,
I tried the steps described in the link u sent me..
but at the end I am getting the following error:

$>lvextend -L+3G /dev/VolGroup00/LogVol00
 Extending logical volume LogVol00 to 10.03 GN
 device-mapper: reload ioctl failed: Invalid argument
 Failed to suspend LogVol00

My Fedora-8 guest is running following:
kernel -->2.6.21-2950.fc8xen 
Device-Mapper--> device-mapper-multipath-0.4.7-11.fc7
device-mapper-libs-1.02.22-1.fc8
device-mapper-1.02.22-1.fc8

LVM-->lvm2-2.02.28-1.fc8

The last few lines of /var/log/messages (after
attempting to "lvextend" the logical volume), as
follows:

[root at localhost ~]# tail -f /var/log/messages 
Mar 20 22:49:12 localhost dhclient: bound to

Will appreciate any further feedback.

Thanks,
kamdard.

I googled on "reload ioctl failed: Invalid
argument",found a few hits describing this to be a
possibly kernel or DM bug.
