Hi,
the autofs on our clients is configured to use LDAP, so there's one
more layer.
This is the current setup:
# autofs on LDAP server
/etc/sysconfig/autofs:SEARCH_BASE="ou=cephfs,ou=AUTOFS,[...]"
# LDAP config
-fstype=ceph,name=autofs,secretfile=/etc/ceph/autofs.key,nodev,nosuid

Hi Eugen
I configured auto.master and a mount point file auto.ceph with the

Hi all.
Is there any way that I could calculate how much time it takes to add
OSD to my cluster and get rebalanced or how much it takes to out OSD
from my cluster?
Thanks.

We have a dev cluster to test things on ceph, that only have one 1gig nic
network. Although it can work we noticed major impact with latencies when
the cluster is balancing or under heavy load.

Hi,
I have a question regarding Ceph CRUSH. I have been going through Crush.h
file. It says that *struct crush_bucket **buckets * (below) is an array of
pointers. My understanding is that this particular array of pointers is a
collection of addresses of six scalar values namely __s32 id; __u16
Hi,
we had bad blocks on one OSD and around the same time a network switch
outage, which seems to have caused some corruption on the mon service.

I'm happy to announce the another release of the go-ceph API
bindings. This is a regular release following our every-two-months release
cadence.

The bindings aim to play a similar role to the "pybind" python bindings in the
ceph tree but for

Hi everyone,
I'm looking for a proposal for this month's Tech Talk on the 25th at

We are using multiple filesystems in production (Nautilus). While we
have had a number of issues over the past year, I don't think any of
them are specific to the use of multiple filesystems.

I wonder if there is any (theoretical) advantage running a separate
backend network next to the public network (through vlan separation) over
a single interface
I googled a lot and while some blogs advice to do so, they do not give any
argument that supports this statement

Hello,
really thanks for your answer. I will try to investigate to the 2nd problems,
and I will keep you informed if I find something.
For the first one, I am experimenting cache pool as you pointed me to, I never
tried it because the ceph documentation doesn't really encourage this with rbd.

Hello,
What is the current status, of using multiple cephfs?
In octopuss I get lots of warnings, that this feature is still not fully
tested, but the latest entry regarding multiple cephfs in the mailinglist is
from about 2018.
Is someone using multiple cephfs in production?
Thanks in Advanc
Those df's and PG numbers all look fine to me.
I wouldn't start adjusting pg_num now -- leave the autoscaler module disabled.
Some might be concerned about having 190 PGs on an OSD, but this is
fine provided you have ample memory (at least 3GB per OSD).
Cheers, Dan

Oh ok. Because we have two types of ssds. 1.8TB and 3.6TB.
The 1.8TB got around 90-100pgs and the 3.6TB around 150-190pgs

I did this on my cluster and there was a huge number of pg rebalanced.
I think setting this option to 'on' is a good idea if it's a brand new
cluster.

This way we can see how the pools are configured and help recommend if
pg_autoscaler is worth enabling.

Hi,
I agree with "someone" -- it's not a good idea to just naively enable

If you're curious about this feature, it would be harmless to start
out by enabling it with pg_autoscale_mode = warn on each pool.
This way you ca

Hi Reed,
you might want to use bluefs-bdev-migrate command which simply moves
BlueFS files from source path to destination. I.e. from main device to

It needs neither OSD redeployment nor additional/new device creation.
Neither it guarantees that spillover reoccurs one day tho

As Paul already answered in your previous thread you need to correct
the fsid in your ceph.conf. The ceph-disk activate-all should work as
soon as the config file is correct.
Zitat von Zhenshi Zhou :
Yep, I think the ceph_fsid tells OSDs how to recognize the cluster. It
should be the same
