Hi, I'm currently running a big mongodb cluster, around 2TB, (sharding + replication).
And I have a lot of problems with mongo replication (out of syncs and need to full replicate again and again datas between my mongo replicats). So, I thinked to use rbd to replicate the storage and keep only sharding on mongo. (maybe with some kind of shard failover between nodes with corosync). NODE1 NODE2 NODE3 ----- ----- ------ [shard1] [shard2] [shard3] | | | | | | /dev/rbd0 /dev/rbd1 /dev/rbd2 Has somebody already tested such kind of setup with mongo ? _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
