Description Jaspreet Kaur 2017-07-25 08:13:46 EDT

Description of problem:  We need to document backup and restore procedure for CNS

currently tried :


- backup everything found under 
    - /var/lib/glusterd
    - /var/log/glusterfs
    - /etc/glusterfs

In case of a disaster restore the steps taken are as follows:
1. Detach gluster related data disks (e.g. /dev/xvdc)
2. Delete the old OpenShift cluster (remove VMs)
3. Create a new cluster with the old hosts inventory (so every config is the same, IPs and such)
4. Attach the gluster related data disks on the same mountpoint ( /dev/xvdc)
5. Restore configuration
5.1 complete etcd restore
5.2 master config restore
5.3 certificates restore

Similar to what we have in Openshift but this doesnt work for CNS.
