Hi,
is adjusting crush weight really a good solution for this? Crush weight out of
the box corresponds to OSD capacity in TB and this looks like a good “weight”
to me. The issue is not in a bucket having wrong weight, but somewhere else
depending on CRUSH.
We actually use “osd reweight” for this

Hi Burkhard,
I seemed to have missed that part but even though allowing access (rwx) to the
cache pool it still has a similar (not same) problem. The VM process starts but
it looks more like a dead or stuck process trying forever to start and has high
CPU (for the qemu-system-x86 process). Whe

I remember when ceph.com was down a while ago - it hurts. Thank you for this.
Cloudflare works and should be free for the website itself.
Not sure how they handle caching of “larger” (not website) objects for
repositories etc, might be plug and play or might require integration with
their CDN.

I would suggest splitting OSDs across two or more SSD journals (depending
on OSD write speed and SSD sustained speed limits)
e.g 2x Intel S3700 400GB for 8-10 OSDs or 4x Intel S3500 300GB for 8-10
OSDs (it may vary depending on the setup)
If you RAID-1 SSD journals they will potentially "wear out
Would love to be a part of this Wido, we currently have a mirror at

The way we currently mirror it does feel a bit clunky and I would welcome a
better way to mirror Cep
I intend to have 5-8 OSDs for 400GB SSD.
Should there be different partitions for each OSD on the SSD?

Yes, there should a separate partition per OSD. You are probably looking at
10-20GB journal partition per OSD. If you are creating your cluster using
ceph-deploy it can create journal partitions for you.

I suspect something more sinister may be going on. I have set the values
(though smaller) on my cluster but the same issue happens. I also find when the
VM is trying to start there might be an IRQ flood as processes like ksoftirqd
seem to use more CPU than they should.
I appreciate your help, I will use ceph-deploy and I will start with 10GB
journal size.

I've been asked to look at the performance of RHEL 7.1/RHCS 1.3. I keep running
into these errors on 1 of my RHEL 7.1 client systems. The rbd devices are still

Hi John,
You are correct in that my expectations may be incongruent with what is
possible with ceph(fs). I'm currently copying many small files(images)
from a netapp to the cluster...~35k sized files to be exact and the number
of objects/files copied thus far is fairly significant(below in bold):
Hi everyone,
A new version of ceph-deploy has been released. Version 1.5.27
includes the following:
- a new "ceph-deploy repo" command that allows for adding and
removing custom repo definitions
- Makes commands like "ceph-deploy install --rgw" only install the
RGW component of Ceph.

I found a way to get the stats you mentioned: mds_server.handle_client_request
& objecter.op_active. I can see these values when I run:
ceph daemon mds. perf dump
I recently restarted the mds server so my stats reset but I still have
something to share:
"mds_server.handle_client_request": 44060
32 matches
