Same client code writing to all 5 clusters? How does the config of the 5th cluster differ from the first 4?
Quick notes: Minimum of 5 nodes for a production deployment to ensure the default 3 replicas are all on different physical nodes. Which is a good segue into the fact that you shouldn't run multiple Riak nodes on the same physical hardware. Performance aside, if you lose that physical machine you lose all your data. @siculars http://siculars.posthaven.com Sent from my iRotaryPhone > On Dec 22, 2014, at 18:59, Claudio Cesar Sanchez Tejeda > <demoncc...@gmail.com> wrote: > > I'm a sysadmin and I managing 5 cluster of RIAK: > > - two of them are LXC containers on the same physical machine (3 nodes > per cluster) > - one of them are LXC containers located on different physical > machines (6 nodes) > - one of them are LXC containers located on different physical > machines and XEN VMs (6 nodes) > - and the last of them are VMware ESX VMs (3 nodes) > > Our application works correctly on the first four clusters, but it > doesn't work as we expected on the last one. > > When we update a key and we retrieve this key in order to write it > again, it has an old value (it doesn't have the first value that we > wrote), for example: > > The key has: lalala > We retrieve the key, and add lololo, so it should be lalala,lololo > We retrieve the key again, and try to add lelele, so it should be now: > lalala,lololo,lelele, but when we retrieve it again, we only have: > lalala,lelele > > In the second write action, when we retrieve the key, we obtained a > key with the old value.
