ceph

Hi, I’m running Plex in an LXC container with the root disk on my local-zfs storage. However, when I try to move the storage to my ceph pool, my local OSD drives disconnect during the process. I tried doing something similar with a larger VM disk (300GB) with no issues. Likewise, when I move...

Hi all disclaimer: I work for Fujitsu, this is a semi-official posting but I hope it is not considered as advertising. ;) I found a couple of discussions in this forum around recommended hardware and components for Primergy servers, so maybe this will be helpful for some of you. Of course we...

Hello, I have a cluster of 9 nodes, with a default crush map and a replication (size) of 3, and min_size of 2. Are there any points against increasing the size to 5 and min_size 3 during operation to handle a higher failure of individual nodes? Enough disk space is available, I am aware of...

We are using Open vSwitch (OVS) for networking in our Proxmox VE cluster. We are experiencing a network issue after restarting a node – Ceph is not immediately ready, and HEALTH_OK status takes several minutes to appear instead of just a few seconds. Observed behavior: • Ping with MTU...

There’s not a whole lot of support forms on the Internet for ceph, so if this is misplaced, I apologize. This is my little one page platform I'm putting together https://github.com/rlewkowicz/micro-platform I use ceph nano to launch a standalone ceph cluster...

Hi ALL, I have a requirement where i need to install & Configure a 3 node Proxmox Cluster with HCI. As part of this setup, I need to configure Ceph storage and enable High Availability (HA). 3*server Configuration: 2CPU - Intel(R) Xeon(R) CPU E5-2697 v4 @ 2.30GHz (18cores) with 10 RAM (32GB)...

Moin zusammen, aktuell setzen wir einen kleinen Proxmox-Cluster jeweils mit lokalem Storage via ZFS ein. Da die Hardware zur Reinvestition ansteht, plane ich einen neuen PVE-Cluster mit CEPH und habe dazu noch ein paar Fragen, die ich trotz Recherche hier und via Google nicht oder teilweise...

Hello, I just want to ask, is it possible for me to install Ceph with Cephadm on a Proxmox node? then I install the RBD from Ceph as a storage disk image / container? I think the Ceph that is included in Proxmox is less customizable, and cannot implement Orchestrator on Ceph Proxmox.

I am relatively new to Proxmox. I had Ceph installed and fully configured and for learning purposes i tried removing it. I removed the Ceph install and rebuilt the whole Ceph setup. I have all the nodes online, but i can't create an OSD. The drives are wiped. NAME MAJ:MIN RM...

Hello all, Here is the situation : We have a Ceph cluster on top of proxmox on Dell Hardware. On of the DELL virtual disk failed, hence the corresponding OSD failed. This is a HDD disk not NVME and "thankfully" the bluestore was not split out on local NVME disks. Anyway, we followed the...

Hello, just after a bit of implementation advice for planning out a cluster. Scenario - VMs running on ceph as a high availability cluster, but attached to each VM is an additional drive which is just for storing ephemeral data as a high-speed cache. This data does not need to survive a...

Mit dem Titel fängt es ja schon mal sehr gut an. Wir haben ein kleines Problem: Wir müssen eine VM aus dem Backup wiederherstellen und leider sind unsere Backups failed. Warum fragen wir trotzdem? Im Backup liegen 5 SCSi Abbilder, welche ursprünglich aus einem Ceph Cluster stammen. Nur die...

Hello, I had OSD 23 on one of my hosts but the drive failed so we stopped the services and removed it. We did not need to replace it immediately (lots of OSDs in the cluster so not a lot of capacity lost) so I didn't pay much attention to it. Sometime in the last couple of months another disk...

I hope this message finds you well. I would like to gain a clearer understanding of the Monitor permissions (mon caps) in Ceph. Specifically, could you explain what actions these permissions allow, and what exactly can be executed or written with them? Thank you in advance :)

Hi, I'm trying to figure out how to upgrade Ceph from 18.2.2 to 18.2.4. I've found this document describing going from Reef to Squid but I want to get to the latest Reef 18.2.4 first. I know I can use that procedure to get to 18.2.4 if I don't update my ceph repo file to squid but then I'll...

What are the best storage configurations in Proxmox to access a SAN with multiple nodes while ensuring high performance, redundancy, and simultaneous access? How do options like ZFS over iSCSI, ZFS over NVMe/TCP, Ceph compare in terms of latency, scalability, and complexity? The goal is to...

I’ve read many threads but haven’t quite figured it out… I know one should not use RAID with Ceph. Do drives connected as JBOD/single drives on a RAID controller (3108) still fall into that warning category? We’re hoping to reuse some older hardware.

Hi all! I have a pve cluster and a cef storage of 3 nodes. On one node, both OSDs are in the down and out status. I need to replace this node with another node. I added a new node to the proxmox cluster, installed cef. Tell me what are my next steps? Do I need to delete the OSD on the node I...

I tried to move my ceph network to another subnet and now all osd's are not picking up the new network and staying down. I fear i may have hosed ceph, but as a learning experience, would like to see if i can recover them. this is what they look like in the cluster: this is the contents of...

We've got a quite serious problem over here. We have added a new node to our cluster. However, when installing ceph on the new node, there was a problem due to the fact that the VLANs for ceph and osd could not communicate correctly (network problem). As a result, we tried to uninstall ceph...
