In our team, we are mostly doing different researches in OpenStack area, so we use bare-metal machines very extensively. To make our lives somewhat easier we've developed set of simple scripts that allow us to backup and restore current state of the file system on the server, it also allows to switch between different backups very easily.
This is how we manage disk partitions and how we use software raid on our machines:
USER_ID - user name
JOB_MODE - possible options:
- upgrade - upgrade standard image to up to date state
- backup - create backup of file system for the defined user
- list - get list of backups for the defined user
- restore - restore from the backup
- standard - restore file system to standard file system
- deploy - deploy stack from scratch according to provided info
Block_Dev_Prov - Which block device provider should be used.
Possible options:
- lvm2
- ceph
STACK_USERNAME - DevStack user name
STACK_GROUP - DevStack group
USER_FOLDER - Folder with user's data
MAPPER - Device mapper path
Mandatory Parameters for LVM:
- VG - LVM Volume group name
- LV_ROOT_STANDARD - LVM Logical standard volume name
- LV_ROOT_FIRST - LVM Logical first root volume name
- LV_ROOT_SECOND - LVM Logical second root volume name
- LV_OPT - LVM Logical opt volume name
- LV_PARTITIONS_LIST - LVM Logical partitions list (root_standard root_one root_two opt_vol)
#-------------Optional values:------------
GIT_LINK - link to relavant stack repository
IF_DEPLOYMENT_FAIL_JOB - which job should be started if deployment fail
BACKUP_ID - which backup ID should be used for recovering. If not defined will be used latest
