  1. Update v6 to v7 went HORRIBLY bad

    Please take notice that I'm writing this post with my middle fingers! Earlier today I started updating my hyperconverged pve6 cluster. Family was gone, so I should have plenty of time, OR SO I THOUGHT. I read the update remarks TWICE and updated the local apt cache, in order to have every...
  2. [SOLVED] PVE7 says "No Proxmox VE repository is enabled"

    I mean, what the heck? The repository is right there!? Could this be related to the DNS split horizon entry for download.proxmox.com that I employed?
  3. [TUTORIAL] Firewall rules for a Samba AD DC

    I finally managed to fully enable the firewall (Input+Output DROP) on all of my VMs, including a Samba AD DC and a Samba File Server. Since the firewall macro "SMB" is not sufficient in this case, and because I didn't find an answer in the forums, here are the necessary directives: Samba AD DC...
  4. [SOLVED] Private linux bridge side effect

    Hey there! I ran into a quirk, that I could have foreseen, but I still have to ask for input, in case I'm missing something. I have three VMs that share vmbr0 as net0 and a private bridge (vmbr12) as net1. No other VM nor the Proxmox nodes use that bridge, and also the router does not know of...
  5. [SOLVED] Pxar backup running forever

    Hey there! I've been using PBS mostly for VM backups and I was always satisfied with the quality. Now I try to backup a CephFS and struggle a little bit without knowing where to start. PBS runs natively on my old QNAP NAS with an AMD Jaguar 64 bit SoC and 16 GiB RAM. The backup pool lies on a...
  6. SSL certificate hassle with VNC

    Hallo! Inspired by another post, I learned that usually VNC connections to VMs on other nodes are supposed to work. But for me, they don't. So I tried to dig into that and it's probably related to my self-signed certificates. Unfortunately, neither of the tutorials I found, were able to solve...
  7. Efficiently backing up CephFS to ZFS

    Hi there! I serve a CephFS via Samba to my hosts and would like to backup the shares to my PBS running a raidZ2. Is there an elegant and efficient way of doing so? Maybe even incremental? What are your recommendations? Regards Marco
  8. Redistribute traffic over bond

    Hey there! I have three nodes in a cluster with Ceph connected to a switch with two NICs each in 802.3ad bond mode. I noticed that one node hardly uses the second NIC and with most of the traffic going through one NIC the available bandwidth for cluster operations is more limited than with the...
  9. [SOLVED] Ceph safe nearfull ratio

    Recently, I recommended the Ceph calculator from florian.ca a couple of times and now that I'm about to set up a cluster myself, I also consulted it for a safe cluster size. However, I seem to not having grasped every detail of the Ceph concepts. I read somewhere that crush does not place the...
  10. [SOLVED] Configurating cluster networks with Ceph

    Hi everyone! I recently read a lot of stuff about hyperconverged PVE/Ceph clusters and now struggle to see the forest through all the trees. ;-) I (plan to) have a three node Proxmox cluster with 4 NICs in each node (2x 1Gbe, 2x 10 Gbe) and would like to have some advice on which NIC should be...
  11. Ceph-Cluster mit Mon-only-Node sinnvoll im Homelab?

    Hallo! Ich möchte mich in Richtung HA weiterentwickeln, scheue derzeit aber die Verdreifachung meiner Server-Hardware. Daher habe ich überlegt, einen zweiten identischen Node zu beschaffen und diesen zusammen mit dem ersten und einem kleinen SBC (Odroid H2) im Cluster zu betreiben. HA könnte ich...
  12. [SOLVED] (...once again...) Logging cadence

    Hello everony! Upon setting up an rsyslog server I realized, that proxmox-backup-api logs every ten seconds "successful auth for user backup@pbs" to syslog. Has anyone an idea if I can adjust the logging cadence and if so, where to do it? Regards Marco
  13. [SOLVED] Migration between two nodes with different network settings

    Hello everyone! I ran into a problem and didn't find a solution so far, maybe someone can point me in the right direction. I setup two rather different servers as a pve cluster (with a qdevice aside, so no problem here). One server has 4 NICs that I use physically for management, corosync, VM...
  14. [SOLVED] Am I doing this ZFS thing wrong? "zfs list" shows unexpected values

    Hey there! I managed to install PBS on my QNAP NAS (*yay*) and set up five spinning disks as a raidz2 with 10G SLOG. ZFS layout is as follows: root@pbs:~# zfs list NAME USED AVAIL REFER MOUNTPOINT bpool 7.23G 7.73T 7.19G /bpool bpool/pbs...
  15. [SOLVED] Input zu Festplatten gesucht

    Moin! Ich möchte in ein SuperMicro CSE505 einen Proxmox-Server einbauen. Platz ist darin für 4x SSD sowie 1x SATA-DOM oder 1x M.2 2280. Derzeit sind eingebaut 4x SA500 2TB sowie 1x SuperDOM 16GB, aber noch innerhalb der 14 Tage Rückgabefrist, d.h. grundsätzlich änderbar. Ich plane, etwa 10 VMs...
