Meu servidor Xen está usando o LVM para os domUs. Eu desliguei um domU e aumentei de 10G para 24G:
lvextend -L24G /dev/xen-disks/my_domu
que parece ter funcionado:
--- 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
Eu posso ver o espaço extra dentro do domU, mas minhas tentativas de aumentar o tamanho de /dev/xvda1 para fazer uso dele falharam.
As informações da partição da domU de dentro:
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
Disk identifier: 0x000e84db
Device Boot Start End Blocks Id System

e são informações de montagem:

Alguma idéia de ser capaz de usar esse 14Gb?
