hey sonal!! Actually right now we have 11 node cluster each having 8 disks of 3oogb and 8gb ram,
now what we want to do is to replace those 300gb disks with 1 tb disks so that we can have more space per server. we have replication factor 2. my suggestion is .. 1:- Add a node of 8 tb in cluster and run balancer to balance the load. 2:- free any 1 node(repalcement node)..... question:- does the imbalance size in cluster is of any datanode create a problem...or have any bad impact regards Vikas Srivastava On Tue, Sep 13, 2011 at 5:37 PM, Sonal Goyal <sonalgoy...@gmail.com> wrote: > Hi Vikas, > > This was discussed in the groups recently: > > http://lucene.472066.n3.nabble.com/Fixing-a-bad-HD-tt2863634.html#none > > Are you looking at replacing all your datanodes, or only a few? how big is > your cluster? > > Best Regards, > Sonal > Crux: Reporting for HBase <https://github.com/sonalgoyal/crux> > Nube Technologies <http://www.nubetech.co> > > <http://in.linkedin.com/in/sonalgoyal> > > > > > > > On Tue, Sep 13, 2011 at 1:52 PM, Vikas Srivastava < > vikas.srivast...@one97.net> wrote: > >> HI , >> >> can ny1 tell me how we can migrate hadoop or replace old hard disks with >> new big size hdd. >> >> actually i need to replace old hdd of 300 tbs to 1 tb so how can i do this >> efficiently!!! >> >> ploblem is to migrate data from 1 hdd to other >> >> >> -- >> With Regards >> Vikas Srivastava >> >> DWH & Analytics Team >> Mob:+91 9560885900 >> One97 | Let's get talking ! >> >> > -- With Regards Vikas Srivastava DWH & Analytics Team Mob:+91 9560885900 One97 | Let's get talking !
