  1. Are there expected integrity problems with incremental backups for clients without ECC-RAM?

    Hi there, see title. For example you have a baremetal Debian client and you secure it with the Proxmox Backup Server: Could a client destroy a whole backup-chain which has been going on for a few months/years because some backup contains corrupted data though bit-flips in RAM? Thanks in advance!
  2. External Corosync QDevice via WAN/VPN

    Hello Proxmox-community, I want to develop a 2-node cluster-concept. Is it possible to have a QDevice via VPN, for example in a datacenter? Multiple ISP-uplinks (DSL, Cable, Fiber, LTE) with failover are mandatory of course. I'm not talking about datacenter to datacenter interconnect fiber...
  3. Ceph: Recommended size for caching SSD in a hybrid cluster

  7. Proxmox VE 6.0-6 ZFS Replication issues/bug with 3 nodes

    Hey there Richard, I've read the wiki and this specific warning, this is why I've set the following HA-Profile: as you can see, it's set to "nofailback" - so if pve01 comes back online again, it shouldn't be the more preffered node or not? Thank you for your reply.
  8. Proxmox VE 6.0-6 ZFS Replication issues/bug with 3 nodes

    Hello, I've been tinkering with Proxmox since a few days and I'm trying to have a 3-node failover cluster. I am running 3x Fujitsu RX300 S7 with the following specs: - 2x Intel(R) Xeon(R) CPU E5-2620 - 192GB RAM ECC RDIMM 1333MHz - 8x SAS 300GB 2,5" with RAIDZ2 - 1x Dual 10GBit Card -...
