Glance (and friends - Cinder etc) work with the RBD layer, so yeah the

I found a partial answer to some of the questions:
5./ My questions:
- Is there a simple command for me to check which sessions are
active? 'cephfs-table-tool 0 show session' does not seem to work
- Is there a way for me to cross check which sessions belong to
which clients (IPs)?

Hi All...
I have some questions about client session in CephFS.
1./ My setup:
a. ceph 9.0.3
b. 32 OSDs distributed in 4 servers (8 OSD per server).
c. 'osd pool default size = 3' and 'osd pool default min size = 2'
d. a single mds
e. dedicated pools for data and metadata
2./ I h
Ahh, and because that was my first insight into placing object into my ceph
pools I (Incorrectly) made some assumptions!

Aha, it seems like '--mark-init auto' (supposedly the default arg to
ceph-disk activate?) must be failing. I'll try re-activating my OSDs
with an explicit init system passed in.

Hi all, thanks for the replies.
So my confusion was because I was using "rados put test.file someobject
testpool"
This command does not seem to split my 'files' into chunks when they are saved
as 'objects', hence the terminology
Upon bolting openstack Glance onto Ceph I can see hundreds of small

Any idea why OSDs might revert to 'prepared' after reboot and have to
be activated again?
These are older nodes which were manually deployed, not using ceph-deploy.

The kernel client does not yet support the new RBD features of exclusive-lock,
object-map, etc. Work is currently in-progress to add this support in the
future. In the meantime, if you require something similar, you can script your
mount commands around the existing RBD advisory locking approa
We now have a gitbuilder up and running building test packages for arm64

Cavium (thank you!).
Trusty aarch64 users can now install packages with
