RBD PVC/PV script

This document provides instructions for using the rbd_pv script to perform Ceph maintenance actions such as backing up and recovering PVCs within your Kubernetes environment.

Usage

Execute utilscli rbd_pv without arguments to list usage options.

utilscli rbd_pv
Backup Usage: utilscli rbd_pv [-b <pvc name>] [-n <namespace>] [-d <backup dest> (optional, default: /tmp/backup)] [-p <ceph rbd pool> (optional, default: rbd)]
Restore Usage: utilscli rbd_pv [-r <restore_file>] [-p <ceph rbd pool> (optional, default: rbd)]
Snapshot Usage: utilscli rbd_pv [-b <pvc name>] [-n <namespace>] [-p <ceph rbd pool> (optional, default: rbd] [-s <create|rollback|remove> (required)]

Backing up a PVC/PV from RBD

To backup a PV, execute the following.

utilscli rbd_pv -b mysql-data-mariadb-server-0 -n openstack

Restoring a PVC/PV Backup

To restore a PV RBD backup image, execute the following.

utilscli rbd_pv -r /backup/kubernetes-dynamic-pvc-ab1f2e8f-21a4-11e9-ab61-ca77944df03c.img

Note: The original PVC/PV will be renamed, not overwritten.

Important: Before restoring, you must ensure the PVC/PV is not mounted!
