Default storage unavailable (was Rsync error 12 when importing raw image)

Hello. I’m setting up a new server using Incus as my hypervisor.

I’ve found that my root partition was full after try to import a 500GB VM raw image (Windows 2012 one). I’ve found that /var/lib/incus/disks was full, so I stopped Incus, restarted it, but same thing happened. Then reboot the computer and now root seems ok in space. But now I have my containers stopped and when I try to start them I’m receiving

Error: Storage pool “default” unavailable on this server

so I did incus storage list

+---------+--------+-------------+---------+-------------+

+---------+--------+-------------+---------+-------------+
| default | lvm    |             | 6       | UNAVAILABLE |
+---------+--------+-------------+---------+-------------+

and then incus storage show default

config:
  lvm.thinpool_name: IncusThinPool
  lvm.vg_name: default
  size: 894GiB
  source: /var/lib/incus/disks/default.img

I was getting crazy and then I’ve found that no default.img file exists, but
source: /var/lib/incus/disks/default.img in my storage config....

What could be happening?

EDIT3: trying incus admin recovery:

incus admin recover
This server currently has the following storage pools:
 - default (backend="lvm", source="/var/lib/incus/disks/default.img")
Would you like to recover another storage pool? (yes/no) [default=no]: 
The recovery process will be scanning the following storage pools:

Would you like to continue with scanning for lost volumes? (yes/no) [default=yes]:

Then converted it to raw using qemu-img convert -f vhdx -O raw

When I choose ‘1’ to begín the import process executing bin.linux.incus-migrate.x86_64 I’m getting this rsync error:

Additional overrides can be applied at this stage:
1) Begin the migration with the above configuration
2) Override profile list
3) Set additional configuration options
4) Change instance storage pool or volume size
5) Change instance network

Please pick one of the options above [default=1]:
