Any idea would be appreciated:)

Hi everybody,
We've runned a 50TB Cluster with 3 MON services on the same nodes with OSDs.
We are planning to upgrade to 200TB, I have 2 questions:
1. Should we separate MON services to dedicated hosts?
2. From your experiences, how size of cluster we shoud consider to put

If you think about stability, simplicity and redundancy - yes.
2. From your experiences, how size of
Hello,
we do not see a problem in a small cluster having 3 MON on OSD hosts.
However we do suggest to use 5 MON's.
Near every customers of us does this without a problem! Please just
make sure to have enough cpu/ram/disk available.
So:

working well.

Hi,everyone
I found libcephfs API, redefine "struct ceph_statx" instead of "struct
stat", why not use "struct stat "
directly and I think it may be better understandable and more convenient to
use for caller.
struct ceph_statx {
uint32_tstx_mask;
uint32_

That's kind of unrelated to Ceph, but since you wrote two mails already,
and I believe it is caused by the mailing list software for ceph-users...
Your original mail distributed via the list ("[ceph-users] Ceph 10.2.11 -
Status not working") did
*not* have the forged-warning.

Hi Alex,
We are using ceph mostly for shared filesystem with cephfs. As well as
some rbd images for docker volumes and a little s3 data. I have been
looking for a plan that can backup datas on rados level. But maybe I should
backup data seperately.
Thanks for the reply.

Hi all, I have a ceph cluster running luminous 12.2.5.
In the cluster, we configured the cephfs with two MDS server,
ceph-mds-test04 is active and ceph-mds-test05 is standby.
Here is the MDS configuration:

Hi Oliver, Peter
Thanks, about an hour after my second email I sat back and thought about
it some more and realised this was the case.
I've also fixed the CEPH issue, a simple set of issues compounding into
ceph-mon's not working correctly.
1. We had power failure 7 days ago. Which for some reas
Thanks Mr Konstantin and Martin,
So with 200TB Cluster, the most afforadable choice is adding MON to OSD
hosts, and preparing enough CPU, RAM for MON services and Storage for
levelDB.
