Allocating Space To Mounts

My real objective is to clean existing nodes from a Hadoop cluster, claim the space etc. and do a fresh installation of another distro.

Below is the space descr. of one of the master(namenode):

Code:
df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/vg00-root
                      2.0G  739M  1.2G  39% /

/dev/mapper/vg00-Zookeeper
                      917G  200M  870G   1% /opt/hadoop-Zookeeper

And one of the slave(datanodes)(the others too have 4-8 local disks and some mounted NFS drives):

Code:
df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/vg00-root

/dev/mapper/vg00-07   559G   33M  559G   1% /opt/hadoop-07

During the new installation, I have run into space issues for all the nodes/hosts

Code:
Not enough disk space on host (l1032lab.se.com). A minimum of 1GB is required for "/usr" mount. A minimum of 2GB is required for "/" mount.
Not enough disk space on host (l1033lab.se.com). A minimum of 1GB is required for "/usr" mount. A minimum of 2GB is required for "/" mount.
Not enough disk space on host (l1034lab.se.com). A minimum of 1GB is required for "/usr" mount. A minimum of 2GB is required for "/" mount.
Not enough disk space on host (l1035lab.se.com). A minimum of 1GB is required for "/usr" mount. A minimum of 2GB is required for "/" mount.

Now the installation requires a lot of space under /, /usr, /var and /home mounts which on both master and the slaves is less but there is lots of space in master under these two disks:

Code:
/dev/mapper/vg00-FSImage
                      917G  200M  870G   1% /opt/hadoop-FSImage
/dev/mapper/vg00-Zookeeper
                      917G  6.5G  864G   1% /opt/hadoop-Zookeeper

and on slaves under these 8 disks.

Code:
/dev/mapper/vg00-00   559G   33M  559G   1% /opt/hadoop-00
/dev/mapper/vg00-01   559G   33M  559G   1% /opt/hadoop-01
/dev/mapper/vg00-02   559G   33M  559G   1% /opt/hadoop-02
/dev/mapper/vg00-03   559G   33M  559G   1% /opt/hadoop-03
/dev/mapper/vg00-04   559G   33M  559G   1% /opt/hadoop-04
/dev/mapper/vg00-05   559G   33M  559G   1% /opt/hadoop-05
/dev/mapper/vg00-06   559G   33M  559G   1% /opt/hadoop-06
/dev/mapper/vg00-07   559G   33M  559G   1% /opt/hadoop-07

I'm a bit confused as how to proceed - I was wondering if I can partition one or more of these disks and allocate those under /, /usr etc. and proceed with the installation but then will these disk partitioning and mounting/un-mounting corrupt the existing /, /usr etc. mounts ?

Command used #
df -hx tmpfs -x swap -x iso9660

why?
to exclude swap and iso9660 filesystem type.

what is required now?
Option1:
Is there a way wherein we give both the file system type with only one "-x" in the above given command?
Option2:
How to declare this as a variable in the beginning of the script? e.g. TYPE=iso9660,swap,tmpfs,etc.

Now i want to _shrink_ the HOME partition so I can expand my VAR partition. Looked for guides but haven't found any site useful so far

I tried to find a way to do it when I installed it but it didn't seem to offer me this at this time even I looked around for a while.

How do I do this shrinking of HOME and extending of VAR partition??
please be fairly specific as Im not a pro yet

What Is The /dev/mapper Partition On Ubuntu 12.05.4 And How Did I Install It?

I am running two linux web-servers. One I am just setting up. On the other, I noted the following partition:

But on the one that I am installing, so far I get this:
Code:

How did I get /dev/mapper partition?

Xubuntu MBR Partioning Question

I was wondering if I can repair my current partitioning setup using gparted, or if I should just reload Xubuntu. Basically I screwed up by making the primary partition only 256M, and made a massive extended logical partition for everything else, and did not leave swap space. I am doing this on an older PC with MBR, dual processor, 2G RAM each processor, 160GB hard drive space. It is single boot, no Windows. I would like the partioning to be as follows, leaving empty disk space for other Linux flavors:

/ 13GB ext4
/home 50GB ext4
swap 8GB swap

I have looked if any hidden file might cause the issue, no joy.

So as far as I understand, only /hadoop is a suitable suspect (as cumulative size of all the other folders on "/" are well below the 365GB)

All folders from 1 to 15 are on different filesystems, so the folder disk16 seems to be the only option but there is nothing in it.

Code:
[root@srv_omega hadoop]# cd disk16/
[root@srv_omega disk16]# ls -lrtha

I just don't get it; no folder seems responsible for the "365Gb"...

Any idea on how I could try to find out where those "365GB" are ?

Virtual CentOS 6.4 Server Expand Disk For Splunk Instance

As I'm sure there are other posts for this, I'm terrified to mess with disks in Linux as I'm very green. I've looked at one other post which suggests to run the following so I'm going to do the same. The drive provisioned originally had 400 gb, but currently has 500 gb allocated in vmware. Thanks so much in advance!

New To LVM, How To Bridge Between /dev/sd* And /dev/mapper/vol Group/log Vol?

So LVM has taken me by surprise, especially working with all of these virtual servers.

I have Linux servers in VMWare, and I know how to grow hard disks there and how they are tied back to /dev/sd*, however what I'm not sure about is how do I know what Volume Group and Logical Volume they are tied too?

If I isssue df -ha I can see where the various partitions are tied to /dev/mapper/Vol Group/Logical Vol

and I issue fdisk -l and I can see the space and what is tied to /dev/sd*, however how do I tie to two together so I know who has what space and how to grow or shrink that space?

I found an older thread he

http://www.linuxquestions.org/questi...ds-for-699073/

However I still don't understand how to bridge between the two.

thanks

Directory Not Visible In Df -H Command

Hi All,
I have drive /u01 mounted on /.
Earlier, the output of df -H did show /u01 entry. Now this command does not show any entry for "/u01". However, I can access all the data in it.
Can someone tell me what this issue is and how to resolve it?
Thank you in advance !!!

Mounting A USB For Vbox

I am installing VirtualBox on Centos per http://www.digitesters.com/centos-in...adless-system/, and I don't understand the very end. Seems like Line 5 is not needed as it is already done on Line 4, right?

Code:
# mkdir /data/virtual_machines/vbox/vbusbfs
# chown vboxuser.vboxusers /data/virtual_machines/vbox/vbusbfs
# chmod 775 /data/virtual_machines/vbox/vbusbfs
# echo "none /data/virtual_machines/vbox/vbusbfs usbfs rw,devgid=$(awk -F : '/vboxusers/ {print $3}' /etc/group),devmode=664 0 0" >> /etc/fstab
# echo "none /data/virtual_machines/vbox/vbusbfs usbfs rw,devgid=$(awk -F : '/vboxusers/ {print $3}' /etc/group),devmode=664 0 0" >> /etc/fstab
# mount -a

I executed the above script (except didn't execute Line 5, and my user:group is vbox:vbox and not vboxuser.vboxusers, and the folder is at /home/vbox and not /data/virtual_machines/vbox), and the following was added to /etc/fstab. Please explain what Line 4 did and what the below line in my fstab file means.
Code:
none /home/vbox/vbusbfs usbfs rw,devgid=496
504,devmode=664 0 0

I then executed mount -a, and got the following response. The part about /var/www/main/ayb_resources and /var/www/main/ayb_cache does not exist is probably some old stuff which I can get rid of, but I am particularly interested in "mount point 0 does not exist" as it seems to be related to the above.

Code:
[root@devserver vbox]# mount -a
mount: special device /var/www/main/ayb_resources does not exist
mount: special device /var/www/main/ayb_cache does not exist
mount: mount point 0 does not exist
[root@devserver vbox]#

My total fstab file is as follows:
