That's not wrong, those are expected objects that contain information
about your rbd images. If you take a look into the rbd_directory
(while you have images in there) you'll find something like this:
host:~ $ rados -p pool listomapkeys rbd_directory
id_fe976bcfb968bf
id_ffc37728edbdab
name_01673d5d-4b12-4a44-8793-403581f7d808_disk
name_01673d5d-4b12-4a44-8793-403581f7d808_disk.config
name_volume-8a1a0825-1163-44bc-abe2-1a711daea07b
The rbd ls command uses the rbd_directory object to read from, an
excerpt from rbd man page:
---snip---
ls [-l | –long] [pool-name]
Will list all rbd images listed in the rbd_directory object.
---snip---
The gateway.conf is your iSCSI gateway configuration stored in the cluster.
Zitat von icy chan <icy.kf.c...@gmail.com>:
Hi,
The numbers of object counts from "rados df" and "rados ls" are different
in my testing environment. I think it maybe some zero bytes or unclean
objects since I removed all rbd images on top of it few days ago.
How can I make it right / found out where are those ghost objects? Or i
should ignore it since the numbers was not that high.
$ rados -p rbd df
