ceph

On an old installation I had PVE and CEPH in the same network. To improve performance and security, I'm currently separating networks more strict. The first step I'm trying is to separate the cluster network from the PVE network. I was following the...

Now I don't know where to ask and post this but I am trying to get my Ceph RBD image mounted again on a new Windows OS install Due to unfortunate disk errors (both SSDs died at same time) I cannot access my previously working Ceph config and keyring for Windows. I did have it working quite...

Hello, I have problems with various VMS that seems do not release unused space. Here is the VM Config: Here is the fstab: Here is the LVM config: Here is the Filesystem free disk space: I've also issued fstrim manually after poweroff/poweron the VM: But when I investigate du on...

I have been running a small (3-node) homelab proxmox cluster with CEPH for almost 5 months. It has been running great and I learned a lot on many levels. So far so good, but yesterday I noticed that two of the three 1TB Samsung SSD Pro NVME drives were in degraded mode because of percentage...

Hey dear Proxmox Pros, I have an issue with my Ceph Cluster after the attempt of migrating it to a dedicated network. I have a 3 node Proxmox Cluster with Ceph enabled. Since I only had one network connection on each of the nodes, I wanted to create a dedicated and separate network only for the...

Hi All Is there any recommendations for configuring pools with differing goals? I am setting two pools with opposite goals. A fast NVMe pool for VM's and a slow cephfs using spinning drives. Considering the different objectives, i was thinking of setting up two ceph clusters. Both would be...

Hi All I have a 3 node cluster with ceph storage. I want to configure the ceph cluster to work with only one node. (in the even of a double failure) Currently the ceph continues working correctly with the failure of one node, but as soon as two nodes are down, ceph becomes unavailable and you...

I'm trying to do a two ceph pools with 3 nodes (Site A) and 3 nodes (Site B) with two different rules. The first rule is a stretched Ceph with Site A and Site B and the second rule is just a standalone ceph rule on Site A. Each of the 6 nodes has 3 OSDs. So total there's 18 OSDs. I'm...

Hello, I am trying to create a high availability Proxmox cluster with three nodes and three SSD's however I can't seem to get it working. The monitoring on two of the three nodes isn't working and I cannot actually create the VM on the share

I'm operating a Dell PowerEdge R740 server as a Ceph node. The current system boot configuration utilizes a single SAS SSD for the OS drive. I'm planning to migrate to an Dell BOSS M.2 SATA drive via PCIe adapter (two drives as RAID 1) (https://www.ebay.com/itm/296760576190) to optimize the...

Hey everyone, I’m running into a serious issue while trying to install Ceph Reef (Windows x64) on my Windows laptop. The installation seems to go smoothly until it prompts me to restart the PC. However, after the restart, my computer goes into automatic repair mode, and I can't seem to get it...

I have 3 HPE Proliant DL360 Gen10 servers that I would like to configure as a 3 node Proxmox cluster. Each node has 6 x 2TB data drives, for a total of 12TB per node + 2 system drives in mirror. Most configurations I have seen relay on an external NAS as the shared storage space. I am specially...

Hi Community! The recently released Ceph 19.2 Squid is now available on the Proxmox Ceph test and no-subscription repositories to install or upgrade. Upgrades from Reef to Squid: You can find the upgrade how-to here: https://pve.proxmox.com/wiki/Ceph_Reef_to_Squid New Installation of Reef...

Howdy, I have a CEPH cluster built on a former vSAN cluster. Right now, there are three nodes, although I do have three more identical servers available. CEPH is slow and I know that I am not getting any new hardware, so I would like to make it run as well as possible. Hosts are BL460G9 with...

Hello, we have a proxmox server cluster with CEPH storage. Today one of the nodes (1/3) was crashed, we rebooted it physically but one of the VMs doesn't boot anymore because the disk is not visible in the CEPH pool. With the command rbd ls “poolname” the disk doesn't appear. Any ideas?

Hallo, ich bin gerade damit beschäftigt unseren ersten Cluster mit Proxmox zu installieren und hätte noch die ein oder andere Frage. Hardware Daten: 6 Server mit je 2x AMD Epyc 9124 768GB RAM 6x 3,84TB NVME SSD 2x 2Port 25G NIC Workload: ~100-120 Windows/Linux VMS Auf den Servern habe...

Hello, We recently built a 3-node PVE hyper-converged cluster w/ ceph and I was wondering about the following: For MTU size on interfaces, does it matter where that is applied? I believe I've found that on linux bridge it is unnecessary as it inherits it from the bond, but what about the...

I've just installed radosgw with apt install radosgw on my Proxmox Ceph 18.2.4 Reef cluster as well as the Ceph dashboard in the hopes of managing the object storage from it, however the dashboard throws a number of internal errors as it requires the rgw module to be enabled. When checking the...

Any guess for Ceph 19.2 implementation on the horizon?

Hi, i get the error message "595 Connection refused" if i try to manage 2 of a 4 nodes cluster. This is a production cluster and every node comes with 1 dedacted 10gig nic which one with 2 ports, one for HA and one for Ceph. The manage network is on default 1gig nic, checking on logs i'll see...
