Hm... on your pty, try:
> python -c "import os; hdd = os.statvfs(FLAGS.instances_path); print
hdd.f_frsize * hdd.f_blocks;"
that is exactly how to calculate total disk.
if you got minus value, something unexpected situation occurs.

I dont think disk space is not cheched on executing live-migration.
available disk space is only checked for kvm-block migration.

e0fd9c27-cc7b-4420-bd8a- 6dd9d5316929 to compute2: Lack of
disk(host:-188978561024 <= instance:37580963840)
In fact I have 170G free disk on compute2, then I check nova
database
and find this in compute_nodes which compute2 have:
disk_available_least: -176
free_ram_mb: 41086
free_disk_gb: -149
my question is that, how nova get disk info and then fill to this db
by the way, horizon seems don't have ability to show host
capabilities
which I can easy to know how much resource left on each node
Thanks
