You have configured your corosync to use the internal ip addresses 172.24.129.85 (biomass) and 172.24.124.27 (pve02) but your machine "biomass" has the ip not configured. Thats why your corosync is not working.
Did you change the IP of "biomass"...
journalctl -b (upload as file here)
cat /etc/pve/corosync.conf on both nodes
pveversion -v
systemctl status corosync
cat /etc/network/interfaces
P.S.: Welcome to the Forum!
Mach Dir keine Sorge, wir alle hier im Forum haben irgendwann mal angefangen.
Den schwersten Schritt hast Du bereits geschafft, Du hast angefangen Dich mit Proxmox zu beschäftigen!
Es ist schwierig Dir zu helfen, wenn Du nicht an deine Maschine...
Nodes failing isnt the issue. the quorum device is meant as defense against a silo connectivity "tie". Anything short of a room losing connectivity would be handled normally without it.
This is a great idea. We use something conceptiually similar to this with any Linux-based OS we have in the field to keep track of changing stuff over the years.
Our implementation is kind of simple: store the bash scripts in a special directory...
I see a problem here and thus i usually discourage from changing the vote strength of devices. Because the setup is inhomogeneous
and thus unpredictable. Exactly for the reason you showed.
Welcome to the Forum!
When updating Proxmox always do a full-upgrade - so apt full-upgrade or apt-get dist-upgrade.
For further information please consult the PVE Administration Guide here.
Best thing is to have 3 replica on 3 locations. i'd advise to buy 8 more m640 for the 3rd room ;-)
Another idea: Make 1 Proxmox server spare and split the other 18 in 3x6 (6 per room) and go for one cluster.
Is that feasable?
Hey!
Back in February this year, after quite a long round of discussions, Proxmox introduced a change in the corosync config that allows for overriding the default token coefficient and lowering it by default. Quick background: By default...
