    [SOLVED] Is pvelocalhost still needed ?

    Hello, I'm sure why but in the past, an entry containing pvelocalhost in /etc/hosts file was mandatory to get a proper node working. It's not specified anymore here : https://pve.proxmox.com/wiki/Install_Proxmox_VE_on_Debian_Buster So, do you think this entry is still needed anymore ? (PVE6...

    [SOLVED] Is verify task needed with ZFS-backed datastore ?

    Hello, On PBS, when using a ZFS datastore, should we really enable verification job ?

AND ZFS scrubbing is done on a regular basis (once a week, a month ?), ZFS is...

    [SOLVED] Separate Ceph and corosync networks on running cluster (PVE5)

Now, I'm trying to migrate corosync (aka pvecm) on a dedicated 1G link, recently added. All my hosts are configured on a new subnet (10.152.13.0/24) and ping...

    C236 & PCIe

    Hello, We're trying to setup a Supermicro X11SSW-F with X520-DA2 10Gbps NIC on a RSC-W-68-P riser card. But the card isn't detected, not even shown on lspci output. The motherboard is based on a C236 chipset but it doesn't seems really well detected. lspci shows : 00:00.0 Host bridge: Intel...

    Migration between ipv4-only and dual-stack hosts

    Hello, We just added 2 PVE 5.1 hosts into our 'old' 4.2 cluster in order to migrate and upgrade old nodes. This old nodes are ipv4 only and new ones are dual-stacked (ipv4 & ipv6). We have setup a dedicated 10Gbps network between all nodes for DRBD replication. It would be great to use it for...

    [SOLVED] Firewall auto-add MASQUERADE rule

    Hello, We just activate firewall on a Proxmox 4.4 installation. We observed that proxmox automatically add a masquerade rule : # iptables-save |grep MASQ -A POSTROUTING -o vmbr0 -j MASQUERADE So we need to delete this rule at every reboot or the VMs are seeing connections from the hypervisor...
