ceph

Hi, i'm exeriencing a strange behaviour in pve@6.1-7/ceph@14.2.6: I have a Lab setup with 5 physical Nodes, each with two OSDs. This is the Ceph Config + Crushmap: Config: [global] auth_client_required = cephx auth_cluster_required = cephx auth_service_required = cephx...

Hello, everybody! Serious trouble. `ceph status` hangs, every ceph command hangs! PVE shows "got timeout" reinstalled the node, tried to join the node just by copying keys, but could not create monitor (error: monitor existed), then I removed the monitor from monmap, and that's it all...

Hello, We now have a well working Ceph cluster with 5 nodes (PVE5.4, Ceph luminous). OSDs are distributed like this : * host1 : osd.12 : 1750 GB osd.13 : 1750 GB * host2 : osd.0 : 894 GB osd.1 : 1750 GB * host3 : osd.5 : 1750 GB * host4 : osd.4 : 1750 GB osd.5...

Dear friends, I have a question on assembling a Proxmox + CEPH (I am a newbie in Proxmox... but a have experience in use VMWare) cluster with 7 servers.

Hi After days of searching and trying different things I am looking for some advice on how to solve this problem :). The performance issue persists in the VM's on Proxmox. They have some old software running on them that requires good random 4K read/write performance and this therefore has a...

I am trying to decide between using XFS or EXT4 inside KVM VMs. My goal is not to over-optimise in an early stage, but I want to make an informed file system decision and stick with that. Situation: Ceph as backend storage SSD storage Writeback cache on VM disk No LVM inside VM CloudLinux 7...

With colleagues, we have been using Proxmox VE for a long time. We want to implement Hyper-Converged Infrastructure (HCI). I read about caching modes in the official documentation https://pve.proxmox.com/wiki/Performance_Tweaks I would like to hear an authoritative opinion. What caching mode...

HI, My 'oldest' prx ceph cluster is based on samsung SM863a drives. After 3 years, wearout for some drives is less than "88% remaining". I don't know if these values are safe enough. Under what kind of Wearout value it is recommended to change the SSD drive ? Thanks !

i have a ceph setup, that is working. i want to connect another another network ( to the cephfs storage) is it possible? what is the best approach? the cpeh is proxmox based (over 40GB network) , the the clients are standalone desktop computers (over 1 gb network)

Hi all, I read a lot of documentation about Proxmox Ceph Cluster but I can't figure out the best solution for my case. I would like to configure a little 3 node cluster using Proxmox and Ceph with the ability of add in the future more nodes (so more CPU and RAM to the cluster) if needed or...

I have one issue... When I migrate a VM's disk from one Ceph storage pool size 2 to another Ceph storage pool size 3 it occupies the maximum capacity configure for the disk in the target Ceph storage, despite the real use of that disk is only a few gigabytes. The attached images are very...

Can not create OSD for ceph. Same error in GUI and terminal: # pveceph osd create /dev/nvme0n1 Error: any valid prefix is expected rather than "". command '/sbin/ip address show to '' up' failed: exit code 1 The only thing i can think of is since last time it worked was that i now have two...
