I want to use ceph rbd, because it shows better performance. But I dont
like kernal module and isci target process. So here is my requirments:
I dont want to map it and mount it , But I still want to use some
filesystem like api, or at least I can write multiple files to the rbd
volume
Sound like cephfs to me

Dear All,
Not sure if this is a bug, but when I add Intel Optane 900P drives,
their device class is automatically set to SSD rather than NVME.
This happens under Mimic 13.2.0 and 13.2.1

Thanks for the advice John.
Our CentOS 7 clients use linux kernel v3.10 so I upgraded one of them to use
v4.17 and have run 10 more node fail tests. Unfortunately, the kernel upgrade
on the client hasn't resolved the issue.
With each test I took down the active MDS node and monitored how long

Please keep the discussion on the mailing list.
With 11 nodes and requirements I'd probably go for 8+2 or 7+3 depending on
the exact requirements.
The problem with +1 is that you either accept writes when you cannot
guarantee redundancy or you have a downtime when one osd is down.
Yes, you can red
Today we pulled the wrong disk from a ceph node. And that made the whole
node go down/be unresponsive. Even to a simple ping. I cannot find to
much about this in the log files. But I expect that the

I didn't lose any clients this time around, all clients reconnected within at
most 21 seconds. We think the very long client disconnections occurred when
both the mgr and mds were active on the failed node, which was not the case for
any of my recent 10 tests. We have noticed in the client logs

Hello people :)
we are facing a situation quite similar to the one described here:
http://tracker.ceph.com/issues/23117
Namely:
we have a Luminous cluster consisting of 16 hosts, where each host holds
12 OSDs on spinning disks and 4 OSDs on SSDs. Let's forget the SSDs for
now since they're not u
You should probably have used 2048 following the usual target of 100 PGs
per OSD.
Just increase the mon_max_pg_per_osd option, ~200 is still okay-ish and
your cluster will grow out of it :)

Hi!
Trying to replace an OSD on a Jewel cluster (filestore data on HDD + journal

I've set noout and removed the flapping drive (read errors) and replaced it
with a new one.
I've taken down the osd UUID to be able to prepare the new disk with the same
osd.ID. The journal device
rgw is not really my area but I'd suggest before you do *anything* you
establish which object it is talking about.

Hi Cephers,
I’m starting to play with the Ceph Balancer plugin after moving to straw2 and
running into something I’m surprised I haven’t seen posted here.
My cluster has two crush roots, one for HDD, one for SSD.
Right now, HDD’s are a single pool to themselves, SSD’s are a single pool to

Hello Ceph Users,
Does anyone know how to set the Cluster Name when deploying with Ceph-deploy? I
have 3 clusters to configure and need to correctly set the name.
Kind regards,

Don't set a cluster name. It's no longer supported. It really only matters
if you're running two or more independent clusters on the same boxes.
That's generally inadvisable anyway.
Cheers,

What is the status of the cluster with this osd down and out?

It seems I got around this issue with the following process.
1. I noted from the error that the pg causing the problem was 2.621.
2. I did “ceph pg 2.621 query” and I saw that that pg had nothing
whatsoever to do with the affected OSD.
3. I looked in the /var/lib/ceph/osd/ceph-14/current directo

Briefly, miserable.
All client IO was blocked.
36 pgs were stuck “down.” pg query reported that they were blocked by
that OSD, despite that OSD not holding any replicas for them,
If you don't already know why, you should investigate why your cluster
could not recover after the loss of a single osd.
Your solution seems valid given your description.

Hello Erik,
We are going to use RBD-mirror to replicate the clusters. This seems to need
separate cluster names.
