Hi Ceph users
I am designing a CEPH system with 6 servers running full NVMe. Do I need to
use 3 separate servers to run the MON services that communicate with
OpenStack, or should I integrate the MON services into the OSD servers?
What is the recommendation? Thank you.

check mtu between nodes first, ping with mtu size to check it.

Hi everyone,
I want to know about the scrubbing state placement group, my cluster has
too many pg in state scrubbing and it's increasing over time, maybe
scrubbing takes too long.

Hi ceph user!
I need to determine which erasure code values (k and m) to choose for a
Ceph cluster with 10 nodes.
I am using the reef version with rbd. Furthermore, when using a larger k,
for example, ec6+2 and ec4+2, which erasure coding performance is better,
and what are the criteria for choos
Only change it with a custom profile, no with built-in profiles, i am
configuring it from ceph dashboard.
osd_mclock_scheduler_client_wgt=6 -> this is my setting

I update the config
osd_mclock_profile=custom
osd_mclock_scheduler_background_recovery_lim=0.2
osd_mclock_scheduler_background_recovery_res=0.2
osd_mclock_scheduler_client_wgt=6

Hi Yang and Anthony,
I found the solution for this problem on a HDD disk 7200rpm
When the cluster recovers, one or multiple disk failures because slowop
appears and then affects the cluster, we can change these configurations
and may reduce IOPS when recovery.
osd_mclock_profile=custom

I'm currently facing a significant issue with my Ceph cluster. I have a

Hi community,
When I list images of rbd in ceph dashboard, Block->Images, list image is

Hi community,
I am running ceph with block rbd with 6 nodes, erasure code 4+2 with
min_size of pool is 4.
When three osd is down, and an PG is state down, some pools is can't write
data, suppose three osd can't start and pg stuck in down state, how i can
delete or recreate pg to replace down pg o
It works!!!
Thanks Kai Stian Olstad
