Subject LVM to JBOD conversion without data loss
Date Mon, 12 May 2014 07:18:24 GMT
Hi I am a query regarding JBOD ,

I sit possible to migrate from LVM to JBOD without loosing data ? Is there
any reference documentation ?

The steps which i can think of is

1) reduce the replication

2) change the hdfs-site.xml in namenode

3) add the data node back with new JBOD directory structure for haddop

4) rebalance the cluster

repeat 1 -4 for all data nodes is the steps correct ?
