Thanks Robert, I'm trying those settings to see if they make a difference for
our case. It's usually around the weekend we have issues so should have some
idea by next week.

hey folks,
I spent the past 2 hours digging through the forums and similar sources with no
luck..
I use ceph storage for docker stacks, and this issue has taken the whole thing
down as I cannot mount their volumes back...
Starting yesterday, some of my nodes cannot mount the filesystem and it j
Thanks for that insight.
My main metrics source is the influx plugin, but I enabled the prometheus
plugin to get access to the per-rbd image metrics.
I may disable prometheus and see if that yields better stability, until
possibly the influx plugin gets updated to support those metric exports.
I'm having a similar issue with ceph-mgr stability problems since
upgrading from 13.2.5 to 13.2.6. I have isolated the crashing to the
prometheus module being enabled and notice much better stability when
the prometheus module is NOT enabled. No more failovers, however I do
notice that even with pr
Ok, then Ceph probably doesn't fit for me.
I wanted to provide a backup platform for me, my family and my friends.
Speed is not relevant, but long-term reliability. So I'm depending on
home internet connections and VPN.
At the moment I'm mostly using wireguard, but I could switch to openvpn

Hi all,
I'm experiencing some stability issues with my ceph-mgr daemons post Nautilus
upgrade (13.2.6->14.2.2).
On top of Ubuntu 18.04, the mgr's are colocated with the mon's, and 2 of the 3
mon/mgr nodes also colocate an MDS, running a single rank active:standby-replay.
The main issue(s) I am
You cannot add OSDs to a cluster that is offline.

Hi,
this was the first thing I was thinking about (and yes, there had been
some issues, but they are resolved - double checked!).
MTU is consistent throughout the whole net and pings in all sizes are
handled well. And MTU problems wouldn't probably make a difference
between backfills and normal o

I was wondering if you were aware of a way to add more OSD nodes to an
existing OFFLINE cluster.

hello
I got a huge difference of read/write performance on my ceph cluster
when I use rbd.
rbd bench reach the limit of my cluster (1gbps network) when the
performance in mapped rbd is very low. 30MB/s.

Dear ceph-users,
I'm having trouble with heartbeats, there are a lot of "heartbeat_check:
no reply from..."-messages in my logs when there is no backfilling or
repairing running (yes, it's failing when all PGs are active+clean).
Only a few OSDs are failing, even when there are several OSDs on the

Hi Tom,
responding back on this briefly so that people are in the loop; I'll
have more details in a blog post that I hope to get around to writing.
