I have configured 3 node proxmox with equal number of OSDs and storage. The storage use keeps increasing despite of the allocated space. The used percentage grows from 99 percent to 100 percent. Why is this happening?

My ceph cluster has 3 3TB and 3 1TB drives with SSD WAL and DB. The write speeds are kinda meh on my VMs, from what I understand the 3 TB drives will get 3x the write request of the 1TB drives. Is my understanding correct ? and would it be better if I swapped my 3TB with 1TB drives making it 2...

Hi We are deploying cloudinit images from terraform (telmate/proxmox), by cloning a template in proxmox already configured with cloud init. The new machine gets created with the next available VMID, and a small 4MBdisk is created to feed the cloudinit settings. The disk created for cloudinit is...

Hi all, we needed to replace a drive caddy (long story) for a running drive, on a proxmox cluster running ceph (15.2.17). THe drives themselves are hot swappable. First i stopped the OSD, pulled out the drive, changed the caddy, refitted the (same) drive. The drive quickly showed up in proxmox...

Hello, maybe often diskussed but also question from me too: since we have our ceph cluster we can see an unweighted usage of all osd's. 4 nodes with 7x1TB SSDs (1HE, no space left) 3 nodes with 8X1TB SSDs (2HE, some space left) = 52 SSDs pve 7.2-11 all ceph-nodes showing us the same like...

Hi collegues, i would like to ask you about migration speed between PVE cluster nodes. I have a 3-node PVE 8 cluster with 2x40G network links: one for CEPH cluster (1) and another one for PVE cluster/CEPH public network (2). CEPH OSDs is all-nvme. In cluster options i've set also one of these...

Dear community, the HDD pool on our 3 node Ceph cluster was quite slow, so we recreated the OSDs with block.db on NVMe drives (Enterprise, Samsung PM983/PM9A3). The sizing recommendations in the Ceph documentation recommend 4% to 6% of 'block' size: block.db is either 3.43% or around 6%...
