Quoting Ralf Müller <ralf@xxxxxxxx>:
Is there a way for a domU to discover size changes of block
devices modified by dom0?
The domU will be aware of the additional space.
Ok - I did it again :)
dom0 > rpm -q xen
xen-3.1.0_15042-51
dom0 > lvdisplay /dev/data0/test-xx
--- Logical volume ---
LV Name /dev/data0/test-xx
VG Name data0
LV UUID U8e3ZH-xMFZ-TwUf-qpi1-r5Ee-y07c-PtskZe
LV Write Access read/write
LV Status available
# open 0
LV Size 1.00 GB
Current LE 256
Segments 1
Allocation inherit
Read ahead sectors 0
Block device 253:47
give it to test domU:
disk=[ 'phy:/dev/data0/test-hda,xvda,w',
'phy:/dev/data0/test-swap,xvdb2,w',
'phy:/dev/data0/test-xx,xvdc1,w',
]

The filesystem is still 1GB. What am I doing wrong?
