I haven't done much with rbd trash yet but you probably should still
see rbd_data.43def5e07bf47 objects in that pool, correct? What if you
deleted those objects in a for loop to "help purge"? I'm not sure if
that would work, though.
Zitat von Anthony D'Atri <anthony.datri@xxxxxxxxx>:
Perhaps setting the object-map feature on the image, and/or running
rbd object-map rebuild? Though I suspect that might perform an
equivalent process and take just as long?

Hi Andre,
I once faced the same problem. It turns out that ceph need to scan
every object in the image when deleting it, if object map is not
enabled. This will take years on such a huge image. I ended up
deleted the whole pool to get rid of the huge image.
Maybe you can scan all the objects in the pool and remove all
objects relevant to this image manually, but I don’t know how.

Hi,
I'm running a 15.2.4 test cluster in a rook-ceph environment. The
cluster is reporting HEALTH_OK but it seems it is stuck removing
an image. Last section of 'ceph status' output:
progress:
Removing image replicapool/43def5e07bf47 from trash (6h)
[............................] (remaining: 32y)
This is now going for a couple of weeks and I was wondering if
there is a way to speed it up? The cluster doesn't seem to be
doing much judging from the system load.
I've created this largish image to test what is possible with the
setup but how do I get it out of the trash now?
# rbd info --image-id 43def5e07bf47 -p replicapool
rbd image 'csi-vol-cfaa1b00-1711-11eb-b9c9-2aa51e1e24e5':

Any pointers how to resolve this issue are much appreciated.

Andre
