Use scsi disk and virtio adapter? I think that is recommended also for
use with ceph rbd.

Rescan
Linux vm
echo 1 > /sys/class/scsi_device/2\:0\:0\:0/device/rescan (sda)
echo 1 > /sys/class/scsi_device/2\:0\:3\:0/device/rescan (sdd)
I have this to, have to do this to:
virsh qemu-monitor-command vps-test2 --hmp "info block"
virsh qemu-monitor-command vps-test2 --hmp "block_resize
drive-scsi0-0-0-0 12G"

Subject: Online disk resize with Qemu/KVM and Ceph
Hi,
I'm making a environment for VMs with qemu/kvm and Ceph using RBD,
and
I'm with the follow problem: The guest VM not recognizes disk
resize
(increase). The cenario is:
Host:
Centos 7.6
Libvirt 4.5
Ceph 13.2.4
I follow the following steps to increase the disk (ex: disk 10Gb
to
20Gb):
# rbd resize --size 20480 mypool/vm_test # virsh blockresize
--domain
vm_test --path vda --size 20G
But after this steps, the disk in VM continue with original size.
For
apply the change, is necessary reboot VM.
If I use local datastore instead Ceph, the VM recognize new size
imediatally.
Does anyone have this? Is this expected?
