Hi, The clocks weren't synchronized because the servers don't have direct access to internet or a NTP server. They can use a http proxy, so I installed and configured htpdate on them in order to maintain their clocks synchronized. The issue was resolved by synchronizing the clocks. Thanks! On T

It sounds like allow_mult is off. 1. What's your last_write_wins set to? 2. Are the clocks on your nodes accurately synced to one another (if they're all NTP peers from one another, what's the deltas?)? I know drift is a common problem in virtual machines on VMWare -- or clocks plain lying. 3. Are

Did you check that you had an intermediate value after the second write as expected? Do you have allow_mult set to true? On 23 Dec 2014, at 03:20, Claudio Cesar Sanchez Tejeda wrote: > Hi, > > On Mon, Dec 22, 2014 at 11:54 PM, Alexander Sicular > wrote: >> Same client code writing to all 5

Hi, Sorry, I forgot to mention that it is RIAK 1.4.10. They are configured with multibackend. We are using, memory, bitcask and elevelDB backends. On the buckets where we are having issues, the siblings are disabled (allow_multi = false). Regards. On Mon, Dec 22, 2014 at 9:17 PM, Sargun Dhillon

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 r

What versions of Riak are you using? And are these CRDT sets? Sent from my iPhone > On Dec 22, 2014, at 16:04, Claudio Cesar Sanchez Tejeda > 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) > -

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
