Title:
Compute service wrong report disk usage when libvirt_images_type is
LVM
Status in OpenStack Compute (Nova):
Fix Released
Bug description:
Heloo,
I obsereved wrong compute node disk usage when I setup
libvirt_images_type to lvm. The compute service still reports
filesystem usage (instances_path) instead of volume group usage
(libvirt_images_volume_group).
Fo exmample:
instances_path ~= 50GB
libvirt_images_volume_group = foo_vg, where foo_vg ~= 1000GB
create few Instances (6GB root volume + 300GB ephemeral),
create a few volumes in same VG (by cinder or nova-volumes of 580GB size)
The status shows:
---------------------
local_gb_used = OK
local_gb = Wrong
free_disk_gb = Wrong
disk_available_least = Wrong
select
s.availability_zone,c.local_gb,c.local_gb_used,c.free_disk_gb,c.disk_available_least
from compute_nodes as c, services as s where s.id=c.service_id and
s.availability_zone='foo_av_zone';
+-------------------+----------+---------------+--------------+----------------------+
| availability_zone | local_gb | local_gb_used | free_disk_gb |
disk_available_least |
+-------------------+----------+---------------+--------------+----------------------+
| some_av_zone | 49 | 306 | -257 |
49 |
+-------------------+----------+---------------+--------------+----------------------+
Instead of:
------------
local_gb_used = OK (ephemeral + root volume)
local_gb = OK (whole space)
free_disk_gb = OK (free = local_gb - ephemeral - root volume)
disk_available_least = OK (free space in vg disk_available_least =
local_gb - ephemeral - root volume - volume)
select
s.availability_zone,c.local_gb,c.local_gb_used,c.free_disk_gb,c.disk_available_least
from compute_nodes as c, services as s where s.id=c.service_id and
s.availability_zone='foo_av_zone';
+-------------------+----------+---------------+--------------+----------------------+
| availability_zone | local_gb | local_gb_used | free_disk_gb |
disk_available_least |
+-------------------+----------+---------------+--------------+----------------------+
| foo_av_zone | 1003 | 306 | 697 |
117 |
+-------------------+----------+---------------+--------------+----------------------+
I attached a patch which "fix" the reporting.
