Hi,
I would like some advice on setting up a replicated or geo replicated setup in Gluster.
Right now the setup consists of 1 storage server with no replica serving gluster volumes to clients.
We need to have some sort of replication of it by adding a second server but the catch is this second server will have spinning disks while the current one has SSD disks.
I have read that in Gluster, the clients are the one running the replication of data by sending the same bytes to the gluster servers, so by using one gluster server with spinning disks the performance of clients will be as fast as a spinning disk speed even when the other server has SSD.
For budget reasons we can't have SSDs in second storage server.
I kept reading and found the geo replication feature which makes the server do the replication of data instead of the clients, which is more likely my case but looks like there is no automatic failover mechanism of it and the administrator need to intervene to make the slave server a master one according to this document:
Given this scenario, I really need a piece of advice from the gluster users on how would be the best approach to have a replicated setup with SSD+HDD storage servers.
Thanks,
