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.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.
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-Starting-Virtual-Demo-Cluster.
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,
Roland
