Hello,
I need advice on the creation of an EC profile and the associate crush rule,
for a cluster of 15 nodes, each with 12 x 18Tb disks with the objective of
being able to lose 2 hosts or 4 disks.
I would like to have the most space available, a 75% ratio would be ideal
If you can give me some
ld storage used only with cephfs and where we store only big files.
We cannot have a full replicated cluster, and we need maximum uptime...
Regards

Hello,
How to simply monitor the growing of db/wal partitions ?
We have 2 nmve shared for 12 osd by host (1 nvme for 6 osd), and we want to
monitor the growing.
We use cephadm to manage ours clusters
Thanks for advance

Hello,
We have a cluster with 21 nodes, each having 12 x 18TB, and 2 NVMe for db/wal.
We need to add more nodes.
The last time we did this, the PGs remained at 1024, so the number of PGs per
OSD decreased.
Currently, we are at 43 PGs per OSD.
Does auto-scaling work correctly in Ceph versio
Thanks for your reply

Hi all
I got many error about PG deviation more than 30% on a new installed cluster
This cluster is managed by cephadm
all box 15 have :
12 x 18Tb
2 x nvme
2 x ssd for boot
Our main pool is on EC 6 + 2 for exclusive use with cephfs
created with this method :
