i have two storage pools with an used_by like


their created_at differ, but that’s irrelevant. The latter has an empty used_by and the former has “/1.0

  "config": {},
  "description": "",
  "name": "default",
  "type": "custom",
  "used_by": [
  "location": "none",
  "content_type": "filesystem",
  "project": "default",
  "created_at": "****"

I’d like to remove the volume from the former pool (SSD), but it tells me “The storage volume is still in use” :

A) What does “/1.0” mean? Doesn’t look like it is in use to me.

B) How do I remove it from the SSD pool? Or how do I move it to the default pool? I can’t edit the former to remove the “used_by”: ["/1.0"] and add it to the latter. I even tried moving from ssd/default to default/default and it gives me “Failed deleting source volume after copy: The storage volume is still in use

/mnt/storage-ssd/custom is empty (also on the default storage pool)

select * from storage_pools

select * from storage_volumes

What does “lxc storage volume show ssd default” show?

The 1.0 is the api version. This is currently always 1.0 for lxd.

Sounds like the /1.0 means the volume is being used by LXD itself. So likely referenced in “lxc config show”

See Server configuration - LXD documentation for storage.backups_volume or storage.images_volume

shows what was posted above:

config: {}
description: ""
name: default
type: custom
- /1.0
location: none
content_type: filesystem
project: default
created_at: 0001-01-01T00:00:00Z

indeed, it shows

  core.https_address: '[::]:8443'
  core.trust_password: true
  storage.images_volume: ssd/default

but if i try to edit, i get:
