If you use 'radosgw-admin bi list', you can get a listing of the raw bucket
index. I'll bet that the objects aren't being shown at the S3 layer
because something is wrong with them. But since they are in the bi-list,
you'll get 409 BucketNotEmpty.
At this point, I've found two different approaches
I'm testing using RBD as VMWare datastores. I'm currently testing with

My Ceph cluster is HDD backed.
In order to help with write latency, I added an SSD drive to my hypervisor

Hello Team,
We aware that ceph-disk which is deprecated in 12.2.2 . As part of my

12.2.2
Here I'm getting activation error on the second hit onwards.
First occurance OSD's creating without any issue.

Thanks David for the suggestion, let me try that :)

Why are you rebooting the node? You should only need to restart the ceph
services. You need all of your MONs to be running Luminous before any
Luminous OSDs will be accepted by the cluster. So you should update the
packages on each server, restart the MONs, then restart your OSDs. After

Hello Team,

My plan is to upgrade all 5 nodes to 12.2.2 Luminous without any downtime.

We have graphs for network usage in graphana. We even have aggregate
graphs for projects. For my team, we specifically have graphs for the Ceph
cluster osd public network, osd private network, rgw network, and mon
network. You should be able to do something similar for each of the
servers in you
You're correct, I was mistaken that a bucket could be renamed. How many
buckets do you have in your RGW? I got away from the buckets that wouldn't
delete by recreating the ceph pool for the data since it was only backup
data at the time.

I found no way to rename the bucket. Neither s3cmd nor radosgw-admin offer a
renaming option (even Amazon S3 does not support renaming).
Deleting the objects did not work:

Hi
we are planning to replace our NFS infra with CephFS (Luminous). Our use
case for CephFS is mounting directories via kernel client (not fuse for
performance reason). The cephfs root directory is logically split into
subdirs where each represent separate project with its own source codes

Hi,
Did you see this http://docs.ceph.com/docs/master/install/get-packages/ It
contains details on how to add the apt repo's provided by the ceph project.
You may also want to consider 16.04 if this is a production install as
17.10 has a pretty short life (

First off, you can rename a bucket and create a new one for the application
to use. You can also unlink the bucket so it is no longer owned by the
access-key/user that created it. That should get your application back on
its feet.
I have had very little success with bypass-gc, although I think it

Hi,
which repository should i take for Luminous under Ubuntu 17.10?
I want a total new install with ceph-deploy, no upgrade.
Is there any good tutorial for fresh install incl. bluestor?

Followup:
I eventually gave up trying to salvage the bucket. The bucket is supposed to
have ca. 11 objects, every attempt to "bucket index check --fix" increased
that number by 11, so something is very wrong.
Also, deleting the bucket with "radosgw bucket rm --purge-objects" failed with

It is probably due to the difference in block sizes used in the test vs
