hi

I have a problem to be fixed by gurus.I am on home environment with VMware workstation 8 and a OEL 6.1 is deployed on it.
The diskspace is enhanced upto 52G from 20G but the existing Guest OS (which is on OEL 6.1) not getting it.
[root@nodeonvm2 Desktop]# fdisk -l

Disk /dev/sda: 55.8 GB, 55834574848 bytes
255 heads, 63 sectors/track, 6788 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Disk /dev/mapper/VolGroup-lv_root doesn't contain a valid partition table

Disk /dev/mapper/VolGroup-lv_swap: 2113 MB, 2113929216 bytes

Disk /dev/mapper/VolGroup-lv_swap doesn't contain a valid partition table
[root@nodeonvm2 Desktop]# 
I just want "/dev/mapper/VolGroup-lv_root" to enhance upto some more gigs upto 2 Gigs more and create others for Testing Some ASM with 11gR2.

kind regards

    You will normally have to extend the size of the logical volume and also the file system residing in it. For instance:

    lvextend -L 2G /dev/VolGroup00/LogVol00
    resize2fs /dev/VolGroup00/LogVol00

    Linux 2.6 kernel supports on-line resize for filesystems mounted using ext3 only.

    so its not happening.
    can we put LVM in hadoops cluster?

    You need to add more space to the Volume Group:

    create a new partiton, e.g. /dev/sda3
    <pre>
    fdisk /dev/sda
    </pre>
    Create a new primary partition and mark it with hex code 8e (linux lvm)

    Then try again:
    <pre>
    vgextend /dev/VolGroup /dev/sda3
    lvextend -L+20G /dev/VolGroup/lv_root
    resize2fs /dev/VolGroup/lv_root
    </pre>

    hi

    After the previous step i transfers some files to newly created different mount point but disk space has increased so fast.how to find the reason ?? As it is a VM ware environment So I suspect for enhancement is for some unused files are kept under VHFS.how do i clean them?

    You can try to find out which directory is eating all your root disk space:

    <pre>
    du -ms /*
    </pre>

    [root@nodeonvm2 VMwareDnD]# pwd
    /tmp/VMwareDnD
    its replicating the copied file(s) from host to gust OS.
    how to find if any process filled up the spaces?

    kind regards

    Apparently this folder is created a temporary space for files which you drag & drop (DnD) to the VM's.
