after GC: unreal project quota is displayed

[temirg]

Hello Harbor-devs,

we have a strange problem here: after the GC, a project quota is set to about 1 percent of
the space actually occupied by the images in the project.

our environment:
both harbors: standalone server
docker-25.0.6_ce
docker-compose-2.22.0
harbor v2.11.1-6b7ecba1

harbor-1
replica-1-to-harbor-2: push-based, Flatten All Levels, Scheduled
replica-2-to-harbor-2: push-based, Flatten All Levels, Event based

df -h /data
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/harbor-harbor 2.0T 1.3T 733G 64% /data

harbor-2

df -h /data/
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/harbor-harbor 2.0T 1.3T 736G 64% /data

---

The problem first discovered in Harbor 2.7.4 and tried the following:

• deleted all images from the project-1 (harbor-1, in harbor-2 automatically deleted by the event based replica)
• deleted project-1 in harbor-1 and harbor-2
• run GC in both harbors
• rm -rf /data/registry/docker/registry/v2/repositories/project-1 on the OS level
• created project-1 again in both harbors, let the customer push the images in harbor-1/project-1

Interim result: both harbors show about 38 GiB used in the project.
Run GC again in both harbors.

Final result:
harbor-1/project-1 - quota: 398.37MiB of 100GiB
harbor-2/project-1 - quota: 37.99GiB of 100GiB

What I don't understand: after the GC, the "wrong" project quota should be displayed in both harbors.
Why only in harbor-1?

Regards, temirg.

GC on both: "Allow garbage collection on untagged artifacts" is enabled
