  1. Ceph 15.2.11 upgrade : insecure client warning disappear and reappearing

    Hello, In follow to https://forum.proxmox.com/threads/ceph-nautilus-and-octopus-security-update-for-insecure-global_id-reclaim-cve-2021-20288.88038/post-389914, I'm opening a new thread. I was asked to check this : # qm list prints the PID qm list # print all open files of that process, which...
  2. [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...
  3. [SOLVED] Is verify task needed with ZFS-backed datastore ?

    Hello, On PBS, when using a ZFS datastore, should we really enable verification job ? AFAIK, when there's some kind of redundancy (multiple copies, RAIDZ or mirroring), checksum not disabled (why would you do this ?) AND ZFS scrubbing is done on a regular basis (once a week, a month ?), ZFS is...
  4. [SOLVED] Ceph : delta in reported total space

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

    Hello, In the past, I made a mistake : using the same 10G network to run proxmox cluster AND Ceph cluster. I know, that's bad practice. 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...
  6. 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...
  7. 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...
  8. [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...
