2019. december 22. vasárnap 17:00-tól Ceph intro and reinvention party
lesz a space-ben, alább következik null meghívója:
The purpose of this event is to introduce interested people to the ceph
data-storage ecosystem (1). And have fun ofc ^^
What will happen depends on the people who show up:
Ill give a high level introduction to the components and to why/how ceph
works, then everyone can create a ceph cluster with guidance on their
notebook(2) or together on a hsspace's test cluster.
We can dive deep into the details:
- How exactly ceph stores data
- What are the advanced usecases and how to adapt the cluster/hw for it
- What are the pitfalls/mistakes that can lead to disaster
- How to debug your cluster
Scenario 3 (reinvent):
With a help of a test cluster we will try to use ceph like noone did it
I have a few terrible ideas.
For example: Can you use ceph as an "efficient" data synchronization
Problem: You want to keep a remote copy on a remote host of a directory.
Solution: You run a ceph cluster on your notebook (1 mon/mgr/osd), and
you have an osd remotely. You go offline, then you make changes to your
filesystem (rbd). The next time you go online, only the changed blocks
(objects) will synchronize, giving you an efficient remote copy (as
opposed to rsync, but comparable to zfs send).
(1) : In computing, Ceph is a free-software storage platform, implements
object storage on a single distributed computer cluster, and provides
interfaces for object-, block- and file-level storage. Ceph aims
primarily for completely distributed operation without a single point of
failure, scalable to the exabyte level, and freely available.
(2) : Requirements: min. 2?gb free ram, gnu/linux!
