Hi all,
Same question with CEPH 10.2.3 and 11.2.0.
Is this command only for client.admin ?
client.symphony
key: AQD0tdRYjhABEhAAaG49VhVXBTw0MxltAiuvgg==
caps: [mon] allow *
caps: [osd] allow *
Traceback (most recent call last):
File "/usr/bin/ceph-rest-api", line
Thanks both of your reply.
Hi haomai.
If we compare the RDMA with Tcp/Ip stack, as I know, we can use the RDMA to
offload the traffic and reduce the CPU usage, which means the other
components can user more CPU to increase some performance metrics, such as
IOPS ?
Hi Deepak,

Oh wow, I completely misunderstood your question.
Yes, src/osd/PG.cc and src/osd/PG.h are compiled into the ceph-osd binary which
is included in the ceph-osd rpm as you said in your OP.

Hi Nick,
I didn't test with a colocated journal. I figure ceph knows what it's
doing with the journal device, and it has no filesystem, so there's no
xfs journal, file metadata, etc. to cache due to small random sync writes.
I tested the bcache and journals on some SAS SSDs (rados bench was ok

Hello Ceph community!
I would like some help with a new CEPH installation.

What can I do?
Could you please help me solve the problem?

Hi Peter,
Interesting graph. Out of interest, when you use bcache, do you then just
leave the journal collocated on the combined bcache device and rely on the
writeback to provide journal performance, or do you still create a separate
partition on whatever SSD/NVME you use, effectively giving t
Hi Alexandro,
As I understand you are planning NVMe for Journal for SATA HDD and collocated
journal for SATA SSD?
Option 1:
- 24x SATA SSDs per server, will have a bottleneck with the storage
bus/controller. Also, I would consider the network capacity 24xSSDs will
deliver more performance tha
Nope. This is a theoretical possibility but would take a lot of code change
that nobody has embarked upon yet.

ceph speeds up with more nodes and more OSDs - so go for 6 nodes with
mixed SSD+SATA.

Hi everyone!
I have to install a ceph cluster (6 nodes) with two "flavors" of
disks, 3 servers with SSD and 3 servers with SATA.
Y will purchase 24 disks servers (the ones with sata with NVE SSD for
the SATA journal)
Processors will be 2 x E5-2620v4 with HT, and ram will be 20GB for the
OS, and 1.
