Hi, we have a ticket at Vates regarding this.
(Ticket#7765809)

What is the procedure to replace a faulty HD in a Xostor/Linstor host with 4 HDDs?
4 x Hosts (Redundancy: 2)

Tested this and it worked;

So to understand it...

To get IPMI info from Supermicro;

Can the Host access the IPMI internally, or does it need to talk to it by the main NIC (sharing IPMI) or do I have to open FW access from the host to the dedicated IPMI interface?

In version 8.3, do I need to install any plugin, or should it work by itself? It isn't now.

Why is the Rolling pool update not available when using Xostor?

@nikade
It is solved.
Reinstalled the nodes since the setup is not in production yet.
Bond worked fine and the switch ports went from LACP fall back into LACP active/active.

Have the same problem.
We use LACP fallback in the switch so if the ports in the LACP not receive LACP one port goes into standard mode/non LACP. That's what is active now.

Trying to create a bond with the eth0 (currently used to manage) and eth1 but can't select bond mode.

Have also in the switch enabled native vlan that is the manage vlan.

Can the backed-up machines in Synology Active Backup for business be imported into XCP-ng and spined up as VMs?
They can be started as VMs in Synology Virtual Machine Manager.

Some questions about XOSTOR

Storage between the servers is not shared as a large file system like Gluster. Right?
So for example, each 4 hosts has 2TB storage then the max HD space is 2TB (widely)

Is the NIC speed of the storage network important? Is 2x40G on each server for this overkill?

What software raid on the NVME disks is recommended?

Having centralized storage sounds dangerous from the perspective of failure.
(We already have a 2PB all flash Vast storage.)
