Hi, everyone.
Sometimes, I've got a need to know the ip address of the ceph client at the
time, is there any way to list those ip address in ceph cluster?
Thank you:-)___

Hi,
I'm currently investigating a case where Ceph cluster ended up with
inconsistent clone information.
Here's a what I did to quickly reproduce:
* Created new cluster (tested in hammer 0.94.6 and jewel 10.2.3)
* Created two pools: test and rbd
* Created base image in pool test, created snapshot
Hi Andras,
Iam not the experienced User but i guess you could have a look on this object
on each related osd for the pg, compare them and delete the Different object. I
assume you have size = 3.
Then again pg repair.
But be carefull iirc the replica will be recovered from the primary pg.

Hi all,
In top of our ceph cluster, one application use the rados gateway/S3.
This application did not use multipart s3 api, but it split files (for example
1 MB) into chunk of desire size (it have to work on top of several type of
storage).
For every tests, the application hang when uploadin

not sure what to do about it. pg repair does not fix it. In fact, the

I was under the impression that when a client talks to the cluster, it
grabs the osd map and computes the crush algorithm to determine where it
stores the object. Does the rgw server do this for clients? If I had 12

Hi Gerald,
for the s3 and swift case, the clients are not accessing the ceph cluster. They
are s3 and swift clients and only discuss with the RGW over HTTP. The RGW is
the ceph client that does all the interaction with the ceph cluster.

If it gets to rm, then it's probably not tunables. Are you running

Anything in dmesg?

Hi,
One of our OSDs have gone into a mode where it will throw an assert and die
shortly after it has been started.
The following assert is being thrown:

You should be able to use the rados CLI to list all the objects in
your pool, excluding all objects associated with known, valid image
ids:
rados ls -p rbd | grep -vE "($(rados -p rbd ls | grep rbd_header |

Thanks for your response. Here is what I am setting them to:
I am installing all binaries in the folder:
~/src/vanilla-ceph/ceph-install. So the folder contains the following

Hello Brad,
I manually deleted the py and pyc files under /usr/lib/python2.7/dist-packages
and that seems to have worked. The ceph command does not complain right now.
But I just noticed during the installation that there was an error installing
some python packages:
TEST FAILED:
/home/ssd/sr
The output from a working run of ceph is not very helpful.

I understand. We'll leave it at that and I will get back to you if I see
further issues.

Hi Christian,
Thank you for your explanation. Based on your suggestion, I have put
writeback cache-mode. But, currently the write ops is more better than read
ops. I mean "dd if=/dev/zero of=/dev/rb0" is more better than "dd
if=/dev/rb0 of=/dev/null". Do you know what's wrong here?

It is possible to add a warning message in rbd to say if memory is too low?
