Hi all,
I'd like to update the tunables on our older ceph cluster, created with firefly
and now on luminous. I need to update two tunables, chooseleaf_vary_r from 2 to
1, and chooseleaf_stable from 0 to 1. I'm going to do 1 tunable update at a
time.
With the first one, I've dumped the current
Thank you Greg,
Another question , we need to give new destination object , so that we can
read them separately in parallel with src object . This function resides
in objector.h , seems to be like internal and can it be used in interface
level and can we use this in our client ? Currently we us
Thanks Paul and Janne

initiated a deep scrub on the placement group, which cleared the error.

Hi,
we are seeing a trend towards rather large RGW S3 buckets lately.
we've worked on
several clusters with 100 - 500 million objects in a single bucket, and we've
been asked about the possibilities of buckets with several billion objects more
than once.
From our experience: buckets with tens of

Hi Nathan,
Indeed that was the reason. With your hint I was able to find the
relevant documentation:
https://docs.ceph.com/docs/master/cephfs/client-auth/
that is completely absent from:
https://docs.ceph.com/docs/master/cephfs/quota/#configuration
I will send a pull request to include the lin
Please don't start new deployments with Luminous, it's EOL since last
month: https://docs.ceph.com/docs/master/releases/schedule/
(but it'll probably still receive critical updates if anything happens
as there are lots of deployments out there)
But there's no good reason to not start with Nautilus
Yes, this is power-failure safe. It behaves exactly the same as a real
disk's write cache.
It's really a question about semantics: what does it mean to write
data? Should the data still be guaranteed to be there after a power
failure?
The answer for most writes is: no, such a guarantee is neither

The client key which is used to mount the FS needs the 'p' permission
to set xattrs. eg:
ceph fs authorize cephfs client.foo / rwsp
That might be your problem.

Hi Thomas,
We did some investigations some time before and got several rules how to
configure rgw and osd for big files stored on erasure-coded pool.
Hope it will be useful.
And if I have any mistakes, please let me know.

Hello Jason,
it seems that there is something wrong in the rbd-nbd implementation.

The problem not seems to be related to kernel releases, filesystem types or the
ceph and network setup.
Release 12.2.5 seems to work properly
Dear ceph users,
We have been recently trying to use the two quota attributes:
- ceph.quota.max_files
- ceph.quota.max_bytes
to prepare for quota enforcing.
While the idea is quite straightforward we found out we cannot set any
additional file attribute (we tried with the directory pinning, too

We were trying to implement this however having issues in assigning the

There is a rados command "rados -p cp " , is
