osd

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...

Hi, I am trying to create Ceph OSD(Squid) on a hard drive from Proxmox web GUI but it failed. Please tell me how to fix it! Here's log: https://pastebin.mozilla.org/5zwd5RVA Thank you in advance!

Hello, I work for multiple clients and one of them wanted us to create a Proxmox cluster to assure them fault tolerance and a good hypervisor that's cost-efficient. It's the first time we put a Proxmox cluster in Production environment for a client. We've only used single node proxmox. Client...

Hello everyone! I have a question regarding CEPH on PROXMOX. I have a CEPH cluster in production and would like to rebalance my OSDs since some of them are reaching 90% usage. My pool was manually set to 512 PGs with the PG Autoscale option OFF, and now I've changed it to PG Autoscale ON. I...

I tried to remove all OSD's from a cluster and recreate them, but 2 of them are still stuck in the ceph configuration database. I have done all the standard commands to remove them, but the reference stays. # ceph osd crush remove osd.1 removed item id 1 name 'osd.1' from crush map # ceph osd...

Hello, I've added some more drives to our 3 node ceph cluster, started creating OSDs and accidently created LVM,CEPH (DB) disk instead of OSD. I do not need a seperate DB disk. How can i destroy it and re-create it to regular OSD? Actually i did the same mistake on two nodes. Here's output...

Hi, Could anyone help how to configure OSD with iSCSI??

Hi everyone, I'm working with a 3 node cluster running with ceph 17 and I'm about to upgrade. I also add a new node to the cluster and install ceph 18.2 . The first OSD i'm creating seems OK yet after a few moments it's shut down. In the logs here is what I can find : May 18 15:34:44 node4...

Hey all, I'm having trouble clearing some warnings from my ceph cluster. 1.) HEALTH_WARN: Reduced data availability: 1 pg inactive pg 1.0 is stuck inactive for 5m, current state unknown, last acting [] 2.) HEALTH_WARN: 2 slow ops, oldest one blocked for 299 sec, daemons [osd.0,osd.1] have...

Hello, I'm managing a cluster of 4 nodes using proxmox 7.4-17 with CEPH. After a messy shutdown caused by a long power outage, a couple of VM images were corrupted, but we could restore them from backup. However, two of the OSD services refuse to come back, showing this kind of error: Apr 18...

Long story short... not possible. I'm planning to install and use ceph and HA in my working cluster enviroment. I have 4 nodes with 256GB RAM each and 2x10G NICs dedicated for ceph cluster network traffic. I already know this may be not enough for perfect performance so I'm planning to swap NICs...

Greetings community! After few month of using ceph from Proxmox i decided to add new disk and stuck with this issue. ceph version 17.2.7 (2dd3854d5b35a35486e86e2616727168e244f470) quincy (stable) Running command: /usr/bin/ceph-authtool --gen-print-key Running command: /usr/bin/ceph --cluster...

I need to build a 4 node Ceph cluster and I need an effective capacity of 30TB. Each node is configured like this: Supermicro 2U Storage Server 24 x NVME, X11DPU, Dual 1600W 2 x Intel Xeon Gold 6240 18 Core 2.6Ghz Processor 768G Ram 2x 100G Network 6 x Samsung PM9A3 3.84TB PCIe 4.0 2.5...

Hi, when I try to attach a new osd to my ceph cluster, I get an error regarding the link https://quay.io/v2/ I would like to know where this error comes from and why ? And what is the real use of the quay.io/v2/, does ceph retrieve information on the remote server ? Thanks in advance Error...

Just written down for your amusement, on a lazy, dark and rainy Sunday afternoon: Someone (me) might try to extend a Ceph cluster by adding NVMe (or other SSDs) via USB3 Adapters. For a small homelab this should be feasable, isn't it? My three PVE nodes already run a single Ceph OSD on an...

Hi, I'm trying to build a hyper-converged 3 node cluster with 4 OSD each on proxmox but I'm having some issues with the OSDs... First one is the rebalance speed: I've noticed that, even over a 10Gbps network, ceph rebalance my pool at max 1Gbps but iperf3 confirm that the link is effectively...

Hi, i had created a 3 Nodes Proxmox cluster with 3 Lenovo M720Q (for simplicity i call the nodes N1,N2 and N3). Then i had added 4 disks (D1, D2, D3 and D4). All was working fine. Then i move all the SFF PC and the disk from my desk to the rack but unfortunately i do not write down the...

Hello, We have a failed OSD disk to replace on a production server. We have to hot replace it using remote hands in data center. Are theese steps correct? 1.Set global OSD flags: noout/norebalance/nobackfill 2.Out and destroy failed disk 3.Wipe failed disk under Disks /dev/sdx 4.Physically...

Hi everyone, I have a 3 nodes cluster running on PVE 6.4 with a total of 24 SSDs with CEPH. Considering that: - the cluster can be brought to a total stop - each node is more than capable to host all the machines - new SSDs are bigger (from 960GB to 1.92TB) - I'd highly prefer to not stress the...

I run a 3-node PVE with CEPH. I migrated all VMs away from node 3, upgraded to the latest CEPH (Quincy) and then started the PVE 7 to 8 upgrade on node 3. After rebooting node 3 (now PVE 8), everything seemed to work well. So I migrated two VMs, one each from node 1 (still on PVE 7) and node 2...
