As it should be working, I will increase the logging level in my
smb.conf file and see what info I can get out of the logs, and report
back.
I would like to use the native Samba's CephFS VFS interface, but I
could not get Samba ACLs to work when testing it, as it it looks like

Hi,
I need to install Ceph Hammer because of some kernel issues with Jewel by
ceph-deploy tool.
But when I enter “ceph deploy install node1 node2 node3” , ceph deploy starts
installing Ceph-Jewel.
How can I install older versions of Ceph, like Hammer on CentOS 7 ?
Thank you

Hi Oliver
It's all about resources.
If you have lots of CPU and memory it is completely doable.
If you're using lower specification hardware, it might be a little
difficult.

There is potential for locking due to hung processes or such when you have OSDs

That's good to know. My plan is to have three nodes initially; each with every

Hi Alex,
thats no problem.
It might get harder to troubleshoot problems, because the
serverressourced will be used for everything. Also you will have on the
same node logs for every different service.
But in general, its no problem technically to have all ( Mon+Osd+MDS )
on one node.

Hi,
I'm looking at standing up a small Ceph cluster, but I'm curious as to what the
general opinion is around having dual role nodes. E.g. each node is both an OSD
and MON.

Hi,
I wanted to add 2 new nodes (21 OSDs per node) to the current ceph

What is best way doing the same without impacting the customers with
no downtime (and not network impact due to rebalcing activity)?
