Cinder – Block storage services – Storage Nodes
In my case all the three compute nodes will also be storage nodes. In all the three nodes had created a single virtual disk in RAID controller. /dev/sda1 was use for efi boot and /dev/sda2 for OS installation. a new partition /dev/sda3 was created for the remaining space. Install the supporting utility packages apt install…
Cinder – Block storage service – Controller node
Compute nodes will also be used as storage nodes. However we need to install the services in controller node. Create the database, grant privileges CREATE DATABASE cinder; GRANT ALL PRIVILEGES ON cinder.* TO ‘cinder’@’localhost’ IDENTIFIED BY ‘commonpass’; GRANT ALL PRIVILEGES ON cinder.* TO ‘cinder’@’%’ IDENTIFIED BY ‘commonpass’; FLUSH PRIVILEGES; exit Create service credentials . admin-openrc…
