CephFS snapshots operate on a per-directory level (rather than per

wish.

Hi everyone,
OSS Europe is happening in Edinburgh next week, and on Monday there'll
be a Ceph BoF session[1] at 18:00. This is an informal session for
Ceph users and developers to meet up and talk about whatever's on our
collective mind.
Hope to see you there!
Thanks,
John

public addresses in the 192.168.10.x range rather than
the 192.168.40.x range like the others.
So my guess would be that you are intending your OSDs to be in the
192.168.40.x range, but are missing some config settings for certain
daemons.

Check out the "ceph osd dump --format=json-pretty" and "ceph fs dump

to those logs, data pool with ID 1 and metadata pool with ID 2 do not

The docs you're looking at are from the master (development) version of
ceph, so you're seeing commands that don't exist in mimic. You can swap
master for mimic in that URL.
Hopefully we'll soon have some changes to make this more apparent when
looking at the docs.

Hi all,
Since time immemorial, the Ceph CLI has had a mode where when run with
no arguments, you just get an interactive prompt that lets you run
commands without "ceph" at the start.
I recently discovered that we actually broke this in Mimic[1], and it
seems that nobody noticed!
So the question

The utilization (recursive statistics) are also xattrs. Specifically,
you probably want "ceph.dir.rbytes"

Assuming that ansible is correctly running "ceph mgr module enable
dashboard", then the next place to look is in "ceph status" (any
errors?) and "ceph mgr module ls" (any reports of the module unable to

Aside from the obvious (errors are bad things!), m
It's mds_beacon_grace. Set that on the monitor to control the
replacement of laggy MDS daemons, and usually also set it to the same
value on the MDS daemon as it's used there for the daemon to hold off
on certain tasks if it hasn't seen a mon beacon recently.

In general, no. There is a sho
