VM File System expansion
by Punit Dambiwal
Hi,
I read this article and found that we can expand the VM disk online but it
doesn't expand the filesystem of the VM.....
I tried the following but still it didn't work..all the below commands
failed on the host..
I am using :-
1. Ovirt 3.4.3
2. Glusterfs 3.5
https://inthecloud.readthedocs.org/zh_CN/latest/index.html it's
in Chinese but can translate here :-

Virtual Machine File System expansion
<https://translate.googleusercontent.com/translate_c?depth=1&hl=en&prev=/s...>
oVirt 3.4 disks can be online expansion, but for the disk within a file
system requires a separate support for Linux and Windows lists commonly
used method in this expansion.
*Linux file system expansion (libguestfs)*
For details, please refer to libguestfs site

.
1. View disk
# Virt-filesystem --all --long -h -a hda.img
1. Expansion disk copy to be created, while the expansion of 10G
(Assuming the original disk size is 10G)
For RAW format:
# Truncate -r hda.img hda-new.img # Truncate -s + 10G hda-new.img
For QCOW2 and other compressed formats:
# Qemu-img create -f qcow2 -o preallocation = metadata hda-new.img 20G
1. Extended partition size
Ordinary extended partition, / boot partition expansion 200M, all the rest
to the / partition:
# Virt-resize --resize / dev / sda1 = + 200M --expand / dev / sda2
hda.img hda-new.img
LVM partition expansion, expansion lv_root logical volume:
# Virt-resize --expand / dev / sda2 --LV-expand / dev / vg_livecd /
lv_root hda.qcow2 hda-new.qcow2

Hi,
I have a lot of qcow2 based vm (from my kvm box) disks and I would like to copy to ovirt them.
Ovirt can use qcow2 based images directly or I need to convert to raw in any case?
I don't have long time for migration, the conversion process takes a long time.
Thanks in advance
Tibor

by Grzegorz Szypa

So it should be or should disable this service?
