On the system I've been testing LVM+XFS with, I've run into a bit of a
dilemma. If I try to resize the a volume more than once, I get the
following error message:

Ok, so now let's reformat that partition and remount it.
------begin reformat------
[root@core /root]# umount /web/
[root@core /root]# mkfs.xfs /dev/web/webvol1 -f

naming =version 2 bsize=4096
log =internal log bsize=4096 blocks=1200
realtime =none extsz=65536 blocks=0, rtextents=0
[root@core /root]# mount -a
[root@core /root]# df

------End Reformat-------
Is this a known bug? This problem isn't actually size dependant, as in the
ammount of the resize itself, as in here:

I'm currently running on a Dell 1550, x3 9GB scsi drives, dual 933Mhz P3,
Adaptec AIC-7899 controller, and 512Mb ram. I used the RH 7.1 installer
from SGI to install the box. Using LVM 0.9.1-b7 tools.
