Hi Xiubo,
Nevermind I was wrong, most the blocked ops were 12 hours old. Ug.
I restarted the MDS daemon to clear them.
I just reset to having one active MDS instead of two, let's see if that
makes a difference.
I am beginning to think it may be impossible to catch the logs that
matter here
Look for unlinked but open files, it may not be Ceph at fault. Suboptimal
logrotate rules can cause this. lsof, fsck -n, etc.

With cephadm you're able to set these values cluster wide.
See the host-management section of the docs.

Hi Ondrej,
When running multiple OSDs on a shared DB/WAL NVME,it is important to take
into account,when designing your redundancy/failure domains,that the loss
of a single NVMe drive will take out a number of OSDs.You must design your
redundancy,so tat it is acceptable to lose that many OSDs

Hello,
I’m going to mainly answer the practical questions Niklaus had.
Our standart setup is 12HDDs and 2 Enterprise NVMe per node which means we have
6 OSDs per 1 NVMe. For the partition we use LVM.
The fact that one one failed NVMe takes down 6 OSDs isn’t great but our
osd-node count is more

Hi
Red Hat Ceph support told us back in the day that 16 DB/WAL partitions
pr NVMe were the max supported by RHCS because their testing showed
performance suffered beyond that. We are running with 11 pr NVMe.
We are prepared to lose a bunch of OSDs if we have an NVMe die. We
expect ceph will
Hi Matthew,
Cephadm doesn't cleanup old container images, at least with Quincy. After a
upgrade we run the following commands:
sudo podman system prune -a -f
sudo podman volume prune -f
But if someone has a better advice, please tell us.
Kind regards,
Sake

Dear all
We have an HDD ceph cluster that could do with some more IOPS. One
solution we are considering is installing NVMe SSDs into the storage
nodes and using them as WAL- and/or DB devices for the Bluestore OSDs.
However, we have some questions about this and are looking for some
guidance
Hi All,
*Something* is chewing up a lot of space on our `\var` partition to the
point where we're getting warnings about the Ceph monitor running out of
space (ie > 70% full).
I've been looking, but I can't find anything significant (ie log files
aren't too big, etc) BUT there seem to be a h
Cool!
Thanks for that :-)

Hi Zac,
Yeap, followed the instructions (ie removed the client) and then re-ran
the commands - say thing.
What in particular do you need to know? :-)
Cheers

I need more information about your cluster before I can determine whether the

Hi All,
In reference to this page from the Ceph documentation:
https://docs.ceph.com/en/latest/cephfs/client-auth/, down the bottom of
that page it says that you can run the following commands:
~~~
ceph fs authorize a client.x /dir1 rw
ceph fs authorize a client.x /dir2 rw
~~~
This will allo
Hi Konstantin,
Thank you for the reply. I tried setting ulimit to 32768 when I saw 25726
number in lsof output and then after 2 disks deletion again it got an error
and checked lsof and which is above 35000. I'm not sure how to handle it.
I rebooted the monitor node, but the open files kept growin
