My Xen server is using LVM for the domUs. I shutdown a domU and increased its lv from 10G to 24G:
lvextend -L24G /dev/xen-disks/my_domu
which appears to have worked:
--- Logical volume ---
LV Path /dev/xen-disks/my_domu
LV Name my_domu
VG Name xen-disks
LV UUID EVe9Va-v1ls-FSVR-OlFZ-5juy-PkJ1-7MxDkZ
LV Write Access read/write
LV Creation host, time fractal, 2015-04-01 13:25:05 -0700
LV Status available
# open 1
LV Size 24.00 GiB
Current LE 6144
Segments 2
Allocation inherit
Read ahead sectors auto
- currently set to 4096
Block device 252:6
I can see the extra space inside the domU, but my attempts to increase the size of /dev/xvda1 to make use of it have failed.
The domU's partition info from inside:
Disk /dev/xvda: 25.8 GB, 25769803776 bytes
255 heads, 63 sectors/track, 3133 cylinders, total 50331648 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

and its mount info:

Any ideas on being able to use that 14 GB?
