    CEPH: osd_pool_default_size > # nodes possible?

    Hello All, I have allocated two nodes in my PVE cluster for storage. The idea is to use cephfs wherever possible, and possibly set up ganesha NFS or samba file share export in containers on the storage nodes for applications that need those. I don't particularly trust the disks I have now...

    How to provide redundancy with an external drive and ZFS?

    I'm using Proxmox on a Intel Nuc using ZFS. It has a single disk (a fast NVME) and an external disk attached (a slow HDD which I could replace with a fastest NVME). I'm using Proxmox Backup Server virtualized on a VM which backups some local and remote VMs and CTs. Other than that, on the same...

    [SOLVED] Redundancy fails when node fails?

    We use ceph as FS on a cluster with 7 nodes. This cluster is used for testing, development and more. Today one of the nodes died. Since all the LXC and KVM are stored on ceph storage, they are completely there, but the configuration of the guests is not available since it's stored on the node...

    mixing vlans and bonding?

    Does anyone know if it's possible to mix bonding and vlas? Say I would like to setup a bond over 2 interface eno1 and eno2, and the interface eno1.3000 and eno1.3001. The main purpose of it is to use iscsi multipath while using the bond for ceph.
