Cannot Remove CUSTOM STORAGE VOLUME

LXD
1

i have two storage pools with an used_by like

“/1.0/storage-pools/ssd/volumes/custom/default”
“/1.0/storage-pools/default/volumes/custom/default”

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": [
    "/1.0"
  ],
  "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)

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

indeed, it shows

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

but if i try to edit, i get:
