Re: [ceph-users] Two clusters on same hosts - mirroring

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

Re: [ceph-users] Two clusters on same hosts - mirroring

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. 2017-08-14 22:27 GMT+02:00 Jason Dillaman

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)? On Mon, Aug 14, 2017 at 4:09 PM, Oscar Segarra wrote: > Hi, > > Anybody has been able to work with mirroring? > > does has any sense

Re: [ceph-users] Two clusters on same hosts - mirroring

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

Hi, Anybody has been able to work with mirroring? does has any sense the scenario I'm proposing? Thanks a lot. 2017-08-08 20:05 GMT+02:00 Oscar Segarra : > Hi, > > I'd like to use the mirroring feature > > http://docs.ceph.com/docs/master/rbd/rbd-mirroring/ > > In my
