8:49 <wayneeseguin> bingeldac / seancribbs I have a question about backend data storage with RIak 

08:50 <seancribbs1> what do you want to know 

08:50 <bingeldac> shoot 

08:50 <wayneeseguin> Can Riak handle merging of say 10 partitions each of 200G and 
looking as a single data store from without? 

08:50 <wayneeseguin> That's a limitation we're trying to figure out a way around 

08:50 <seancribbs> that makes no sense 

08:50 <seancribbs> care to give more detail? 

08:51 <wayneeseguin> Yes, we need to run riak on a VM 

08:51 <wayneeseguin> the VM cannot accept a 2TB partition 

08:51 <wayneeseguin> but it can mount 10 200G partitions 

08:51 <wayneeseguin> We'd like riak to look at all of that as usable by itself even 
thought it's separate partitions 

08:52 <wayneeseguin> Is that possible 

08:52 <seancribbs> use JBOD / LVM 

08:53 <wayneeseguin> seancribbs: That can't be done over NFS IIRC 

08:53 <seancribbs> that's different 

08:54 <wayneeseguin> I was wondering if this 'riak_kv_multi_backend' would be the key 
(I haven't read up on it yet) 

08:54 <dysinger> wayneeseguin: are you talking about AWS & EBS ? 

08:54 <seancribbs> no, that's just for allowing to have different backends per bucket 

08:55 <wayneeseguin> dysinger: no this is a private data center infrastructure 
running on vSphere 

08:55 <dysinger> ah 

08:56 <dysinger> well if it's linux you can use LVM to make your 10 200GB look like 1 2TB drive 

08:57 <dysinger> the push riak on top 

08:57 <wayneeseguin> dysinger: not with NFS though correct? 

08:57 <dysinger> s/the/then 

08:57 <dysinger> no 

08:57 <dysinger> correct 

08:57 <dysinger> AFAIK glusterfs can do this though - not nfs but similar 

08:57 <dysinger> would hate to run riak on any of those though :/ 

08:58 <dysinger> slooooooooooow 

08:58 <seancribbs> yeah, NFS kind of defeats some of the purpose of Riak 

08:58 <wayneeseguin> So basially 'make sure there is the 2TB partition somehow as one
and that's what riak will use' 

08:58 <seancribbs> yes 

08:58 <wayneeseguin> *one partition 

08:58 <seancribbs> or you could have 10 riak nodes 

08:58 <seancribbs> ;) 

08:59 <wayneeseguin> seancribbs: I think we need to have a call with the company
about this 

08:59 <wayneeseguin> and you 

08:59 <wayneeseguin> *riak 

08:59 <* seancribbs> pawns that off to grant 

08:59 <bingeldac> I am on a sabbatical for the next few months 

09:02 <seancribbs> anyway - just email riak@basho.com with more detail, 
we'll get something set up 

09:02 <bingeldac> yep yep 

09:02 <bingeldac> sean, dan, or I can help you out and figure out something 

09:04 <wayneeseguin> k
