Having a live disk and a DR disk in each node doesn't work. Ceph places
its data very differently than to expect that the 2 drives in each node
would be a copy of each other. I'm realizing now that you were talking
about rbd mirroring as being something that would keep a second copy of an
OSD dis
Hi,
In my test/lab I'm working with a single node just for testing
functionality... once it works, I will expand this configuration up to 10
nodes.
I'd like all hosts having a drive for live data and the other for DR and
backup to tape.
Thanks a lot.

Personally, I didn't quite understand your use-case. You only have a
single host and two drives (one for live data and the other for DR)?

I'm sure you can set up 2 different clusters in the same machine and
configure them to mirror RBD's between them. I do not believe that this
has any usefulness other than learning the commands and testing scripts.
No benchmarking will be useful at all and any problems you run into might
just be be
Hi,
Anybody has been able to work with mirroring?
does has any sense the scenario I'm proposing?
Thanks a lot.

Hi,
I'd like to use the mirroring feature
http://docs.ceph.com/docs/master/rbd/rbd-mirroring/
In my environment I have just one host (at the moment for testing purposes
before production deployment).
I want to dispose:
/dev/sdb for standard operatoin
/dev/sdc for mirror
Of course, I'd like to
