ceph

I'm using PVE on three nodes, and have Ceph installed as a distributed storage on these nodes. I now want to access the Ceph storage from other servers as well, via NVMe-oF. So, what I have to do is to extend my node configuration so that the PVE nodes also act as NVME-oF targets. In principle...

First, let me contextualize our set-up: We have a 3 node cluster, where we will be using CEPH for storage hyperconvergence. We are familiarizing ourselves with CEPH and would love to have someone more experienced chiming in: All of our storage hardware are SSDs. (24x 2TB NVMe, 8 per server)...

Wir testen gerade ProxMox als VMWare Ersatz. Ich habe die Schulungen gemacht und bassierend auf dieser ohne große Probleme ein Cluster mit 3 Nodes und Ceph aufbauen können. Heute wollte ich unsere ISCSI NAS hinzufügen, aber das hat nicht so ganz geklappt. Ich konnte auf die LUN zugreifen und...

Hello everyone Quick backstory. We have 2 main programs, both of them are using SQL server on windows. We used Hyper-V, but it wasn't very fast, nor secure enogh (periodic backups). Both of these systems are crucial for our company, so the best way would be to have some sort of continuity of...

I am attempting to write an Ansible playbook that sets up my Proxmox cluster. One issue I'm running into is pveceph install doesn't have a non-interactive option. I've tried setting DEBIAN_FRONTEND=noninteractive on the task like this: - name: Install Ceph environment: DEBIAN_FRONTEND...

Hey Folks, Stashing this here as it's the only solution that worked for me and I will undoubtedly need it again. Given, $> ceph health detail ... [WRN] PG_AVAILABILITY: Reduced data availability: 1 pg inactive, 1 pg incomplete pg 7.188 is incomplete, acting [5,10,43] (reducing pool...

Hi This seems to be the best place / forum to ask question about ceph :) My understanding of ceph is the underlying storage is OSD, these are distributed between nodes. Pools are then created that sit on top of OSD's ... i think OSD's are broken into PG and PG are assigned to Pools I think ...

I'm recreating my ceph cluster due a configuration corruption. I will be reusing the same hardware. The problem is I don't have enough hard drives for two ceph clusters, but there is enough capacity. I know that you can't change the size of a erasure coded pool, but is there any way to override...

Here's what I did. When I first set up the 3-node cluster I only had 1 cable for the storage network, ie. where each host is connected 10Gb/s to a switch so they can use a shared storage scheme (Ceph - to which I'm fairly new and just learning) This week we got the extra cables ordered (because...

Hi I have built a proxmox cluster and im running ceph on there. I have another proxmox node - out side the cluster and for now don't want to connect it to the cluster but I want to share the ceph filesystem - so the rdb and a cephfs so I'm thinking i need to do something like this on the...

Hello Community, I am currently setting up our new 3-Node Proxmox Cluster, pretty new to Proxmox itself. We are Using Full-Mesh with 25Gbit/s cards for Ceph, 10Gbit/s cards for Coro/VMBR and 18 (6 per Node) SATA 6G Enterprise SSDs. Ceph performance took a bit of testing, but we are now at a...

Hi got a 6 node cluster , want to reduce the number of nodes. so lets say i have server A1 and server A4 out of a1..A6 I have ceph installed on all node I want to take the drives (OSD one) out of A1 and install them into A4 with out having to resync the entire drive. I have read its possible...

Hi guys, I have a Ceph pool that I removed by accident and then I readded it back in my proxmox cluster. I had a VM disks in there before I removed and when I added the Ceph pool back in, they're not showing up. I can see that the data is there when I take a look at the storage metrics and run...

I set up a home lab of 3 machines to set up a proxmox cluster so I could learn how to do it. I got through the ceph setup and started setting up a cephfs, but when I set it up, for some reason, I cannot create any VMs on it, and can only use the storage local to each host. I found the content...

Hello! I have a LXC that's on a (deprecated by ourselves) erasure coding pool. I want to move their 20TB mountpoint to a SSD erasure coding pool, without taking down the container. First I tried to take down the container and do a migration, but this activity was taking longer than a week, so...

So I have this cluster in mind: PLEASE keep in mind the availability of hardware be it new/used server/workstation hardware is quit unorthodox and different Here from what's available in the us/eu. for example a single used epyc 9654 costs 10x a 9950x and that's just a single cpu, a single...

I upgraded my Proxmox cluster from the latest 8.4 version to 9.0, post upgrade most things went well. However the Ceph cluster has not gone as well. All monitors, OSDs, and metadata servers have all upgraded to Ceph 19.2.3, however, all of my manager services have failed. They ran for a while...

Good Morning While we were doing upgrades to our cluster (upgraded each memory from 256 to 512 - 3 identical nodes), doing one node at a time and all VM's removed from HA and switched off, we noticed that after a node comes online it takes approximately 20-30 minutes for the Remap/Scrub/Clean...

Hello community! I have a theoretical question for you: In case a proxmox node dies and is reinstalled, can the ceph osds with data be salvaged? Given we know the original fsid, reinstall ceph on the reinstalled node, reconfigure it to the original fsid, can we do just 'ceph-volume lvm...

PVE wiki details you should assign CPU cores to CEPH: https://pve.proxmox.com/wiki/Deploy_Hyper-Converged_Ceph_Cluster It doesn't detail on how it (excluding 25% of the cores from VMs) should be done. How do you run your systems?
