Hi all,
Running into some trouble. I just setup ceph multi-site replication.
Good news is that it is syncing the data. But the metadata is NOT syncing.
I was trying to follow the instructions from here:
https://docs.ceph.com/en/quincy/radosgw/multisite/#create-a-secondary-zone
I see there
I’ve come close more than once to removing that misleading 4% guidance.
The OP plans to use a single M.2 NVMe device - I’m a bit suspcious that the M.2
connector may only be SATA, and 12 OSDs sharing one SATA device for WAL+DB,
plus potential CephFS metadata and RGW index pools seems like a soun
Thanks Christophe,

Hi
We have 20 ceph node, each with 12 x 18Tb, 2 x nvme 1Tb
I try this method to create osd
ceph orch apply -i osd_spec.yaml

Hi Stefan
We use cephfs for our 7200CPU/224GPU HPC cluster, for our use-case
(large-ish image files) it works well.
We have 36 ceph nodes, each with 12 x 12TB HDD, 2 x 1.92TB NVMe, plus a
240GB System disk. Four dedicated nodes have NVMe for metadata pool, and
provide mon,mgr and MDS service

According to news articles, HDDs up to 26TB are sampling. Mind you they’re SMR.
And for many applications having that much capacity behind a tired SATA
interface is a serious bottleneck; I’ve seen deployments cap HDD size at 8TB
because of this. But I di

How would a storage system look like in reality that could hold such an

Hello thanks for the answer
But is there any hard coded limit ? Like in zfs ?
Maybe a limit to the maximum files a cephfs can have ?
All the best

Currently the biggest HDD is 20TB. 1 exabyte means 50.000 OSD

AFAIK Cern did some tests using 5000 OSDs. I don't know any larger
clusters than Cern's.
So I am not saying it is impossible but it is very unlikely to grow a
single Ceph cluster to that size.
Maybe you
