Hello. We've moved on to creating a pool, but I'm confused by what the below options mean. What are size, and Min. Size. and Crush rule? We want to create a PG_NUM of 512 as we do plan to have a total of 12 OSDs once we upgrade our cluster, but we get this error. What would be the recommended...

Great, thank you. That helps.

We plan to get a fourth host. We have one empty drive on each host. I have a total of 4 drive bays on each server. Is it worth to add additional disks in the empty drives? If so how many OSDs would that be?

One OSD per non-PVE drive? Where is there documentation on that?

Hello, I have 3 nodes each with the below 1 SSD - PVE 1 SATA 1 SATA I took this from https://pve.proxmox.com/pve-docs/chapter-pveceph.html#pve_ceph_install_wizard How many OSDs should I have for my 3 node setup? I see this recommends 12 OSDs, but I'm not sure why. Thank you!

Yes - That partition was under 10mb. I was able to delete that partition with fdisk. I re ran the command and the output was successful. :)

This solved my problem. Networking services starts successfully once I removed the 3 default gateways.

I don't want traffic into the CEPH network from the outside. I just want each node to have 3 private networks used for corosync, and the CEPH public/cluster. I'd like to solve the issue with the networking.services error at boot (from my original post). My configuration appears to work and I can...

Would configuring additional IP tables for my 3 additional default gateways solve my problem? See below link. https://www.thomas-krenn.com/en/wiki/Two_Default_Gateways_on_One_System

I'm trying to do the below. I'm using fortinet firewall/switches. Each IP has a VLAN on the switch and is assigned to the ports as a Native VLAN. Why am is networking.services booting failed? Is it reading all traffic from one interface? auto eno2 iface eno2 inet static address...

I have hardware switches and a firewall taking care of the VLAN between the 3 servers. This is configured correctly. Would configuring linux VLAN within my network configuration file solve the failed start? I added the tags to my configuration file, but I'm unfamiliar with how to do it or if...

I'm able to ping the other servers. root@vmhost01:~# ping 192.168.51.30 PING 192.168.51.30 (192.168.51.30) 56(84) bytes of data. 64 bytes from 192.168.51.30: icmp_seq=1 ttl=64 time=0.192 ms 64 bytes from 192.168.51.30: icmp_seq=2 ttl=64 time=0.080 ms 64 bytes from 192.168.51.30: icmp_seq=3...

Hello, I'm getting a FAILED on my networking serivce. I'm not sure what's causing the problem? All networks are working correctly/pingable. The configuration looks correct. Here is my etc/network/interfaces auto lo iface lo inet loopback iface eno1 inet manual auto vmbr0 iface vmbr0 inet...

Hello, During my initial configuration of CEPH I'd like to format some drives on my server before the installation. I use this command to format the drives ceph-volume lvm zap /dev/sdb --destroy but i get a runtime error. How do i know the process completed? root@vmhost3:~# ceph-volume...

I found the solution here. https://pve.proxmox.com/pve-docs/pve-admin-guide.html#pvecm_edit_corosync_conf I just changed both config files below with correct IP. Restart service - systemctl restart corosync - and good. /etc/pve/corosync.conf /etc/corosync/corosync.conf

How do I change my cluster IP address to the preferred subnet? I want it on XXX.XXX.49.10. XXX.XXX.48.10 is for management. Where is this configuration handled?

I ran the update today and i see there are a few packages to install. I updated my node and there was a selection that came up for console encoding. What is the correct selection here? I selected cancel on this screen and didn't make a selection. I wasn't sure what to select. How do I correct...

ok How is CEPH redundant without an OSD on the disk for the operating system and VM files? If OS drive fails other OSDs will rebuild it? I added the SSD into my server and reinstalled proxmox onto the SSD. I did the installation without reformatting my other SATA disks. after my...

Thank you. I will just respond here. My (future) ceph setup will be 3 nodes (clustered). I do have 3 spare SSD 256gb to install PVE onto. I should select ext4 on the SSD, and then configure the other drives during the CEPH configuration? Wouldn't the SSD have an OSD as well?

Isnt there no need to use ZFS when configuring CEPH? I could use ext4 and that would be adequate? I would then be able to utilize each drive and the OSDs will provide the redundancy. Is this correct?
