I would:
Remove one of the 2 TB HDDs first, add the new 8 TB HDD, and then mirror the data from the remaining old 2 TB HDD
but both should work, if you have the free slot
My recipe:
Zpool replace disk
==================
Get disk IDs
ls -l /dev/disk/by-id/*
Get zpool status:
zpool status
this assumes the following disk layout:
Part 1: BIOS Boot
Part 2: EFI
Part 3: ZFS
Copy Partitions from working to new disk, without copying label and UUIDs:
sfdisk -d...
1. You can use hetzners vSwitch feature to get additional official IPs, which you then can use on your VMs/containers.
2. You can set up a vmbrX interface with no physical network interface and a private network, eg 192.268.100.0/24.
Now you can enable ip_forward and create firewall rules to...
1. ping 8.8.8.8 from your container
2. on the host check with tcpdump -ni vmbr0 icmp if you see the packets
3. check if you see the packets on your external interface with tcpdump -ni enp1s0 icmp for the outgoing packets, the sender address should be changed to 192.168.178.126 by the masquerade...
I assume 63.141.251.171 is the gateway, 172 is your proxmox host, so your VM will have to be the next free IP 173:
Subnet: 63.141.251.170/29
Address: 63.141.251.173/29
Gateway: 63.141.251.171
Nameserver: 8.8.8.8 or 1.1.1.1 or 9.9.9.9
Sounds good
So inside your VM configure another of your IPs.
Ping 8.8.8.8
Do
tcpdump -ni vmbr0 icmp
on your host, you should see the ICMP echo request and reply packets.
tcpdump -ni enp3s0 icmp
should show the same, these are the packets leaving/entering your system
Does your proxmox host have an IP in that range? Can you ping the default gw and 8.8.8.8 (Google nameserver)
Is that IP on your vmbr interface?
brctl show
should show your vmbr0 bridge interface, please post your /etc/network/interfaces
Are you allowed to have additional Mac addresses...
Tell us more about your setup. I suppose you have a proxmox server in a server hosting somewhere and a /29 network with a gateway from your provider, like 188.16.12.0/29.
In this example 188.16.12.1 would be your gateway, 2-6 your 5 ips.
ZFS is a complex beast but there is documentation. ;)
Your disks are in one (or more) pools, in that pool you have volumes (filesystems) and blockdevices (zvols)
in case of your dead proxmox server, you just set up a new one, attach your proxmox backup server and restore your vms and...
Der Vorteil von topgrade ist dass es nicht nur die apt pakete updated, sondern auch flatpak, snap, rust etc.
Allerding sind auf einem Proxmox host diese normal nicht installiert
