some tips:
1.if you enabled auth_cluster_required, you may shoud have a check
the keyring
2.can you reach the monitors from your admin node by ssh without passwd

Hi,

any way.
Write rates are very good i
I have read the SK‘s performance tuning work too, it's a good
job especially the analysis of write/read latancy on OSD.
I want to ask a question about the optimize on 'Long logging time', what's
the meaning about 'split logging into another thread and do it later',
AFAIK, ceph does logging async by

ceph-qa-suite repository contains the test snippets, teuthology is the
test framework that knows how to run them. It will pull the appropriate

None of the "new" features are currently supported by krbd. 4.7 will

All,
I was called in to assist in a failed Ceph environment with the cluster
in an inoperable state. No rbd volumes are mountable/exportable due to
missing PGs.
The previous operator was using a replica count of 2. The cluster

Hello,
At my workplace we have a production cephfs cluster (334 TB on 60 OSDs) which
was recently upgraded from Infernalis 9.2.0 to Infernalis 9.2.1 on Ubuntu

It seems that cephfs still doesn't free up space at all or at least that's what

I just installed 3 monitors, using ceph-deploy, on CentOS 7.2. Ceph is 10.1.2.
My ceph-mon processes do not come up after reboot. This is what ceph-deploy

Mounting and unmount doesn't change anyting.
The used space reported by df command is nearly the same as the values
returned by ceph -s command.
Example 1, df output:
ceph-fuse 334T 134T 200T 41% /cephfs
Example 2, ceph -s output:
health HEALTH_WARN

I Have a setup using some Intel P3700 devices as a cache tier, and 33 sata
drives hosting the pool behind them. I setup the cache tier with writeback,
gave it a size and max object count etc:
ceph osd pool set target_max_bytes 5000
ceph osd pool set nvme target_max_bytes 5000
have you ever used fancy layout?

A bit more details about the setup would be nice, as in how many nodes,

This is all via RBD, I am running a single filesystem on top of 8 RBD devices

Hi Mike,
I don't have experiences with RBD mounts, but see the same effect with RBD.
You can do some tuning to get better results (disable debug and so on).
As hint some values from a ceph.conf:
[osd]
debug asok = 0/0
debug auth = 0/0
debug buffer = 0/0
debug client = 0/0
20 matches
