i found the solution :

Create a new LVM physical volume in that new partition. pvcreate /dev/sdb Add the new physical volume to your volume group. vgextend VolGroup /dev/sdab Extend the logical volume containing the filesystem you want to extend. lvextend -l +100%FREE VolGroup/name_of_logical_volume resize2fs /name_of_logical_volume

@Mourad Chahri

1. Is your HDFS disk is same as OS disk ? If so then if your OS disk is LVM then you can extend you can add new disk and extend OS disk.

2. If HDFS is using seperate disk [which is not OS disk] then you can easily mount new disk on a filesystem drive and make changes in config of HDFS to take new disk in effect.

3. If OS disk is not LVM as per point 1, then you can still mount the new disk on a filesystem and add the same disk into HDFS configs by creating "new config groups"
