Dear all,

 as promised, here I am  following up on this thread.

After a some days since the last message on this thread,  most of the insecure connections from clients "magically" disappeared and the latest ones were from not-yet upgraded openstack nova-compute nodes.

Now that all nova nodes are completely up-to-date and rebooted at the same ceph distribution level, we were able to remove the allow_insecure from MONs and all things seems fine.

Thank you again for the insightful suggestions.

Just a quick update: I set auth_allow_insecure_global_id_reclaim to false because all the client sessions we had showed either new_ok or reclaim_ok in global_id_status. No complaints so far. :-)

Zitat von Eugen Block <ebl...@nde.ag>:

The mon sessions dump also shows the global_id_status, this could help identify the clients to focus on. I would recommend to inspect this output:

ceph tell mon.<MON> sessions | jq -r '.[] | .name,.socket_addr.addr,.global_id_status'

and check each client.

While looking at our own mon sessions, it seems like I could probably disable auth_allow_insecure_global_id_reclaim, looks like all older clients are either new_ok or reclaim_ok. And we still have plenty of "con_features_release" entries with "luminous", just FYI. I don't really recall doing anything special with our clients (also OpenStack servers), tbh. We upgraded them along with the Ceph versions, and now it looks okay. Maybe a reboot after an upgrade suffices, I don't know.

Here's the list of possible global_id_status entries with a short comment:

Probably yes, but the list it's too long, so in the middle there's a "..." : that's why I searched for a ceph command able to return all the results for session properties without ellipsing.

For this purpose, in my search I found the command  "ceph daemon mon-name sessions" were I saw the "luminous" word that in my mind was "wrong" from my top post of this thread.

If auth_expose_insecure_global_id_reclaim is true, do you see the client in 'ceph health detail'?

Zitat von Sergio Rabellino <rabell...@di.unito.it>:

this is the output by now that allows normal operation. Changing the third breaks client access (and maybe other bad behaviour)

root@juju-XXX7ca-YY62-lxd-0:~# for i in $(ceph config ls | grep global_id); do echo "Config: $i"; ceph config get mon
 $i; done
Config: mon_warn_on_insecure_global_id_reclaim
true
Config: mon_warn_on_insecure_global_id_reclaim_allowed
true
Config: auth_allow_insecure_global_id_reclaim
true
Config: auth_expose_insecure_global_id_reclaim
true
We could disable the warnings, but is this affordable ?

It's been a while since I dealt with all that global_id stuff:

https://docs.ceph.com/en/octopus/rados/operations/health-checks/#auth-insecure-global-id-reclaim Can you share this output?

for i in $(ceph config ls | grep global_id); do echo "Config: $i"; ceph config get mon $i; done
Config: mon_warn_on_insecure_global_id_reclaim
true
Config: mon_warn_on_insecure_global_id_reclaim_allowed
false
Config: auth_allow_insecure_global_id_reclaim
true
Config: auth_expose_insecure_global_id_reclaim
true

We still allow older clients, but we're aware and don't want the warning.

Zitat von Sergio Rabellino <rabell...@di.unito.it>:

Sorry to bother the list with old questions again, I'm a little new into this list.

But if  'ceph daemon mon.name sessions' does not reports the actual protocol used, how I can find this info ?

Both the configs you asked for are "true": are you saying that I'm concerned on null problem ?

If so (and it may be), why if we remove the allow of insecure_global_id on mon(s) all the VMs stop talking with the underlying volumes ?

Bests.

The output of 'ceph features' (or the mon session output) does not reflect that it's an older client. It just represents a collection of supported features. This has been discussed multiple times on this list. This is not unusual.

Regarding the insecure global_id, does your cluster warn about it? Can you share these configs?

ceph config get mon mon_warn_on_insecure_global_id_reclaim_allowed
ceph config get mon mon_warn_on_insecure_global_id_reclaim


Zitat von Sergio Rabellino <rabell...@di.unito.it>:

Thanks for your prompt reply, dump follows:

# ceph osd dump |grep require_osd_release
require_osd_release octopus
We are aware of this setting and change it on release change (we did in the last days mimic->nautilus->octopus). The very strange thing it's that we upgraded luminous->mimic more than two years ago.

About librados, I get:
# rados -v
ceph version 15.2.17 (8a82819d84cf884bd39c17e3236e0632ac146dc4) octopus (stable)
so it seems fine to me.

What is the output of:
ceph osd dump | grep require_osd_release

Have you upgraded OpenStack (librados) as well?

   Dear list,

     we are upgrading our ceph infrastructure from mimic to octopus
   (please
   be kind, we known that we are working with "old" tools, but these
   ceph
   releases are tied to our openstack installation needs) and _*all*_
   the
   ceph actors (mon/mgr/osd/rgw  - no mds as we do not serve filesystem)
   were upgraded fine as follow:

   > # ceph -v
   > ceph version 15.2.17 (8a82819d84cf884bd39c17e3236e0632ac146dc4)
   > octopus (stable)
   We're using a ubuntu/juju orchestrator for managing ceph (and
   openstack
   too).

   It seems all ok, but if I ask a mon to dump the sessions, we get
   that_all of them_ are on luminous:

   >         "con_features": 4540138292840890367,
   >         "con_features_hex": "3f01cfb8ffedffff",
   >         "con_features_release": "luminous",
   We found this oddity when we tried to unset the "insecure global_id    reclaim" flag and all things got broken, so we had to reactivate
   the flag.

   All ceph network layers are "closed", so we're not so urged to remove
   the flag, but we would like to understand if this is a known
   problem or
   an error done by us.

   Any hints ?

   thanks in advance.
