Hi,
What is the easiest and fastest way to upgrade Ceph clients which are
Openstack instances. We have a lot of Openstack Instances and rebooting
them will take a lot of time as we need to communicate with the end users.
Is there any other way like restarting a cinder service to get those
clients
Can you open a tracker for this Dan and provide scrub logs with
debug_osd=20 and rados list-inconsistent-obj output?

I am a student new to cephfs. I want see the ldout log in /src/client/Client.cc
(for example, ldout(cct, 20) << " no cap on " << dn->inode->vino() << dendl;).
Can anyone teach me? The /var/log/ceph dir on the client is empty.

It respects any blocked requests on the Cluster, and toggles recovery

Recently we moved a bunch of our servers from one rack to another. In

why this happened. However it's brou

This was a little long to respond with on Twitter, so I thought I'd share

Hey all,

Hi Harry,
When dynamic resharding was introduced for luminous, this limit on the
number of bucket index shards was increased from 7877 to 65521. However,
you're likely to have problems with bucket listing performance before
you get to 7877 shards, because every listing request has to read from
Hi Harald ,
We saw in our internal Veeam repo that only 4TB used created more than 10M
objects.
I don't know if Veeam need to list content inside the bucket, that will make
a 500 millions bucket not a good solution at least in our experience with
sharding.
I read someone in the IRC telling that

We have resharded a bucket with 60 million objects from 32 to 64
shards without any problem. (Though there were several slow ops at the
"stalls after counting the objects phase", so I set nodown as a
precaution).
We're now resharding that bucket from 64 to 1024.
In your case I wonder if it was the
We received the large omap warning before, but for some reasons we could
not react quickly. We accepted the risk of the bucket becoming slow, but
had not thought of further risks ...

Hi Maged,
min_alloc_size determines allocation granularity hence if object size
isn't aligned with its value allocation overhead still takes place.
E.g. with min_alloc_size = 16K and object size = 24K total allocation
(i.e. bluestore_allocated) would be 32K.
And yes, this overhead is perman
Nice to hear this was resolved in the end.
Coming back to the beginning -- is it clear to anyone what was the

some better default configs to warn users earlier about too-large
