Hi all cephers.
I don't know if this is the right place to ask this kind of questions, but
I'll give it a try.
I'm getting interested in ceph and deep dived into the technical details of
it but I'm struggling to understand few things.
When I execute a ceph osd map on an hypothetic object that

Hi,
Overload on the storage nodes that run OSDs is normal during the whole copy.
The memory pressure is on the client side. I think it may not work to turn the
dirty_ratio and dirty_background_ratio to small on the ceph storage server side.
Anyway，I will have a try.

Thanks for your expertise sharing.
We have already been using blue store and SSD for journal actually.
The mds_cache_memory_limit I will have a try.

Hello,
As mentioned earlier the cluster is seperatly running on the latest mimic.
Due to 14.04 only supporting up to Luminous I was running the 12.2.9
version of ceph-common for the rbd binary.
This is what was upgraded when I did the dist-upgrade on the VM mounting
the RBD.
The cluster it

This is probably because when CRUSH changes,
I have Mimic Ceph clusters that are hundreds of miles apart. I want to use
them in a multisite configuration. Will the latency between them cause any
problems?

Hi guys
I faced strange behavior of crushmap change. When I change crush
weight osd I sometimes get increment osdmap(1.2MB) which size is
significantly bigger than size of osdmap(0.4MB)

that initially it was firefly

re-adding mailing list.
I've had a quick look at the code and the logic for the
expected_num_objects seems broken, it uses the wrong way to detect
filestore OSDs.

Hi, another question relating to multi tenanted RGW.
Let's do the working case 1st. For a user that still uses the global
namespace, if I set a bucket as world readable (header
"X-Container-Read: .r:*") then I can fetch objects from the bucket via a
url like (e.g bucket0, object0):
I think it's new in 12.2.10, but it should only show up when using
Filestore OSDs. Since you mention that the cluster is new: are you not
using Bluestore?
That being said: the default crush rule name is "replicated_rule", so
"ceph osd pool createreplicated_rule
" is the right way to create a
Hello Everyone,
I have a newly re-created CEPH cluster and cannot create a new pool. I'm
using the following syntax, which has previously worked without issue in
the past:

The resulting error is:

Agree, please file a tracker issue with the info, we'll prioritize
reproducing it.

Thanks for taking the trouble to respond
I noticed some xfs error on the /var partition so I have rebooted the
server in order to force xfs_repair to run
It is now working

Hi
I have the same issue a few months ago. One of my client hung on waiting
for a file writing.
And other clients seems not being effected by it. However, if other clients
access to the same
hanged direcotry, it would hang there as well.
My cluster is 12.2.8 and I use kernel client on other

Hi Florian,
Thanks for the help. I did further testing and narrowed it down to objects
that have been uploaded when the bucket has versioning enabled.
Objects created before that are not affected: all metadata operations are
still possible.
Here is a simple way to reproduce this:
This capability is stable and should merge to master shortly.

Hi,
I have a strange issue
I configured 2 identical iSCSI gateways but one of them is complaining
about negotiations although gwcli reports the correct auth and status (
logged-in)
Any help will be truly appreciated

Thanks for replying.
Not the same machine. Our problem is other writing cephfs process will hung

The application node and storage nodes are independent . The cephfs mounts on

We copy large files to the application node’s cephfs mount point from

Dear all,
i am running a cephfs cluster (jewel 10.2.10) with a ec + cache pool. I plan on
upgrading to luminous around the end of December and wanted to know if this is
fine regarding the issues around 12.2.9. It should be fine since 12.2.10 is
released I guess ?
Cheers,
Markus
Is the cephfs mount on the same machine that run OSD?

Do you then get these types of error messages?

having upgraded my CEPH cluster to Luminous, I plan to add new OSD hosts,

- large pool for object-based cold (or not-so-hot :-) data,
