    Hardware/Concept for Ceph Cluster

    Hello, we are using Proxmox with local storage on a small 3 node cluster. Now we are planning to set up a 4 node cluster with network storage (Ceph), live migration, HA and snapshot functionality. We already have some hardware laying around from dev projects. Now I would like to get some ideas...

    Is Ceph too slow and how to optimize it?

    The setup is 3 clustered Proxmox for computations, 3 clustered Ceph storage nodes, ceph01 8*150GB ssds (1 used for OS, 7 for storage) ceph02 8*150GB ssds (1 used for OS, 7 for storage) ceph03 8*250GB ssds (1 used for OS, 7 for storage) When I create a VM on proxmox node using ceph storage, I...

    Add Hard Disk "Storage Selector" times out

    I am having difficulty when adding a new disk to a vm where the storage selector dropdown is timing out. I assume this is from I/O degradation so the dropdown can't get the list of available NFS or iSCI mounts. But I can't ascertain the cause. The NAS is connected via quad gigabit bond and the...

    4.2 perf is lower then 4.1

    Upgraded 4 of 7 nodes today only to discover than especially two VMs running (Palo Alto - VM200 FWs) use much more CPU than when on pve 4.1 :( Pic 1 here shows VM usage last 24 hour and the jump when migrated onto 4.2.22 around 17:00, the last high jump is me introducing more load on the FW...

    Slower Snapshot-Mode Backups after moving from 3.0 to 4.1

    In Proxmox 3.0, my daily snapshot-mode-backup took 37 minutes to create a 78gig backup file. After installing Proxmox 4.1, this same virtual machine now takes an hour and 40 minutes (1:40:00) to create the same 78gig backup file. When I backup the same virtual machine using stop-mode backup, it...

    CEPH read performance

    7 mechanical disks in each node using xfs 3 nodes so 21 OSDs total I've started moving journals to SSD which is only helping write performance. CEPH nodes still running Proxmox 3.x I have client nodes running 4.x and 3.x, both have the same issue. Using 10G IPoIB, separate public/private...
