Hi Wes,

thanks the `ceph tell mon.* sessions` got me the answer very quickly :-)

Cheers

I'm using my gmail.com address, because the gmail.com dmarc policy is
"none", some mail servers will reject this (microsoft?) others will instead
allow this when I send mail to a mailling list which has not yet been
configured to send mail "on behalf of" the sender, but rather do a kind of
"forward". The latter situation causes dkim/dmarc failures and the dmarc
policy will be applied. see https://wiki.list.org/DEV/DMARC for more details

2023-12-21 Thread Wesley Dillingham 
You can ask the monitor to dump its sessions (which should expose the IPs
and the release / features) you can then track down by IP those with the
undesirable features/release

ceph daemon mon.`hostname -s` sessions

Assuming your mon is named after the short hostname, you may need to do
this for every mon.  Alternatively using the `ceph tell mon.* sessions` to
hit every mon at once.

IIRC there are nuances, there are case where a client can *look* like Jewel but 
actually be okay.
