Process reminders
- create sequence - build bricks > create volume > Set volume options > start volume
- growing a volume - add node > define brick > add brick to volume > rebalance

Creating a brick
- use lvm
- supported filesystems (xfs, ext4)
- use thin provisioned lv - preference (due to 3.5 snapshot delivery)

vol create
vol stop/start
quota on/off, adding and removing entries
self heal status
turning protocols off/on - CIFS (user.cifs) and NFS (nfs.disable)

reusing a brick
 - viewing the xattr
 - deleting xattr
showing a file's relationship with the bricks and translators

Disaster recovery
establish georep
check status - list of states - Initializing || Stable || Failed
