Other OSDs are on other computers, they are just one disk=one osd.
Running "lvm activate --all" output is

active. Skipping activation
this "osd 23" run on ssd and is active and working, but "osd 22" does
not appear here.. Is
other OSDs have
1x8tb, but this host has 2x4tb and just 8gb of ram, therefore we did not
want to make two separate OSDs.

We run Ceph on quite old hardware with quite low traffic. Yesterday we

Hello community,
we have developed a cluster on latest mimic release. We are on quite old
hardware, but using Centos7. Monitor, manager and all the same host.
Cluster has been running for some week without actual workload. There
might have been some sort of power failure (not proved), but at
Hello community,
We are building CEPH cluster on pretty old (but free) hardware. We will
have 12 nodes with 1 OSD per node and migrate data from single RAID5
setup, so our traffic is not very intense, we basically need more space
and possibility to expand it.
We plan to have data on

Hello community,
I am building first cluster for project, that hosts millions of small
(from 20kb) and big (up to 10mb) files. Right now we are moving from
local 16tb raid storage to cluster of 12 small machines. We are
planning to have 11 OSD nodes, use erasure coding pool (10+1) and one
Hello,
Might sounds strange, but I could not find answer in google or docs,
might be called somehow else.
I dont understand pool capacity policy and how to set/define it. I have
created simple cluster for CephFS on 4 servers, each has 30gb disk - so
in total 120gb. On top I build replicated
You need to give us more details about your OSD setup and hardware
specification of nodes (CPU core count, RAM amount)

I think you will get some useful information from this link:

Even though it is dated 2014 - you can get approximate direction.

Hello,
I wonder how good or bad is to reserve space for WAL/DB on the same SSD
as OS or is it better to separate them? And what are recommended size
for WAL/DB partition?
I am building Luminous cluster on Centos7 with 2 OSD per host, each OSD
would be 2 * 8tb disks through LVM.
Anton.
Hello,
We have small cluster, initially on 4 hosts (1 osd per host, 8tb each)
with erasure-coding for data-pool (k=3 m=1).
After some time I have added one more small host (1 osd, 2tb). Ceph has
synced fine.
Then I have powered off one of first 8tb hosts and terminated it. Also
