Can I confirm if this bluestore compression assert issue is resolved in 12.2.8?
https://tracker.ceph.com/issues/23540
I notice that it has a backport that is listed against 12.2.8 but there is no
mention of that issue or backport listed in the release notes.

Thank you for Gregory to provide it.
By the way where to get the pdf for these talks?
Thanks again!

Hey all,
Just wanted to let you know that all the talks from Mountpoint.io are
now available on YouTube. These are reasonably high-quality videos and
include Ceph talks such as:
"Bringing smart device failure prediction to Ceph"
"Pains & Pleasures Testing the Ceph Distributed Storage Stack"
"Ceph
With more testing and checking, we realised that this had nothing to do with
Ceph. One part of the upgrade accidentally changed the MTU of our VMs tap
interface from 9000 to 1500... Sorry for the false warning everyone!

Mine is currently at 1000 due to the high number of pgs we had coming from
Jewel. I do find it odd that only the bluestore OSDs have this issue.
Filestore OSDs seem to be unaffected.

Just a thought - have you looked at increasing your "—mon_max_pg_per_osd” both
on the mons and osds? I was having a similar issue while trying to add more
OSDs to my cluster (12.2.27, CentOS7.5, 3.10.0-862.9.1.el7.x86_64). I
increased mine to 300 temporarily while adding OSDs and stopped
I've experienced the same thing during scrubbing and/or any kind of

I'm running Centos 7.5. If I turn off spectre/meltdown protection then a
security sweep will disconnect it from the network.

I'm also experiencing slow requests though I cannot point it to scrubbing.
Which kernel do you run? Would you be able to test against the same kernel with Spectre/Meltdown mitigations disabled
("noibrs noibpb nopti nospectre_v2" as boot option)?

The magic sauce to get Filestore OSDs to start on a node reboot is to make
sure that all of your udev magic is correct. In particular you need to
have the correct UUID set for all partitions. I haven't dealt with it in a
long time, but I've written up a few good ML responses about it.
On Tue,
Marc,
As with you, this problem manifests itself only when the bluestore OSD is
involved in some form of deep scrub. Anybody have any insight on what
might be causing this?

I upgraded my home cephfs/rbd cluster to 12.2.8 during an OS upgrade to
Ubuntu 18.04 and ProxMox 5.1 (Stretch). Everything is running well so far.

Below are the performance counters. Some scientific workflows trigger
this - some parts of them are quite data intensive - they process
thousands of files over many hours to days. The 200GB ceph-fuse got
there in about 3 days. I'm keeping the node alive for now in case we
can extract some

Hi cephers,
Every so often we have a ceph-fuse process that grows to rather large
size (up to eating up the whole memory of the machine). Here is an
example of a 200GB RSS size ceph-fuse instance:

Hi,
I have a really small homelab 3-node ceph cluster on consumer hw - thanks
to Proxmox for making it easy to deploy it.
The problem I am having is very very bad transfer rates, ie 20mb/sec for

Hi dashboard devels & users,

Aside from the obvious (errors are bad things!),
Hi Jones,
Just to make things clear: are you so telling me that it is completely
impossible to have a ceph "volume" in non-dedicated devices, sharing space
with, for instance, the nodes swap, boot or main partition?
And so the only possible way to have a functioning ceph distributed
filesystem
The adviced solution is to upgrade ceph only in HEALTH_OK state. And I
also read somewhere that is bad to have your cluster for a long time in
an HEALTH_ERR state.
But why is this bad?
Why is this bad during upgrading?
Can I quantify how bad it is? (like with large log/journal file?)
I'm not the expert when it comes to cephmetrics but I think (at least until very
recently) cephmetrics relies on other exporters besides the mgr module and the
node_exporter.

The prometheus plugin currently skips histogram perf counters. The
representation in ceph is not compatible with prometheus' approach (iirc).
However I believe most, if not all of the perf counters should be exported as

Hi Martin,
hope this is still useful, despite the lag.
