hi

I'm trying to install qlustar, but I'm running into several problems.

1. Can I allocate disk partitions myself? The default partitioning is

not suitable for us.

the Qlustar installer always uses the full disk, so custom partitioning on the disk level is not supported. However the disk is used as a physical volume for an LVM volume group, so you can customize filesystem layout at the LVM level.

2. How should I start or query FE node?

The virtual FE node is controlled by systemd and automatically started during the boot phase of the head-node (also shutdown). The corresponding systemd  unit is qlustar-fe-node-vm. See also https://docs.qlustar.com/Qlustar/13/ClusterOS/first-steps-guide.html#sec-Sta....

I don’t know how to operate it when deploying "Spack Package Manager". Also, if I don’t need FE node, what will be the impact?

In a Qlustar cluster you always need an FE node for user access. If you don't want this to be a VM as offered by the installer, you'll have to setup a physical machine for it. An FE node is connected to the external AND cluster-internal LAN so that cluster users can access it from their workstations.

Best,
