Specialized Installation
Primary-Master-Node (vm-node-01)
If you configured a additional Backup Volume on the Storage Nodes, you want to mount them now in the VM-Node.
Log into the Primary-Master-Node and execute the node-configuration script as follows:
/usr/sbin/fc-node-configuration --node-type primary-master-node
Manual Steps
In order to be able to migrate a VM from one carrier to another, a special unprivileged user called transfer will be created. This user is able to open sftp connections to another carrier and fetch a VM's disk file (qcow2 image).
Install a transfer user.
Create the user and generate an SSH private/public key pair (without a pass phrase):
lvcreate -L 60G -n transfer local0 mkfs.xfs -L "OSBD_transfe" /dev/local0/transfer cat << EOF >> /etc/fstab LABEL=OSBD_transfe /home/transfer xfs noatime,nodev,nosuid,noexec 0 2 EOF mount /home/transfer useradd --comment "User which is used for VM disk file transfer between carriers" \ --create-home \ --system \ --user-group \ transfer passwd transfer
