Create Multiple Folders Using R Codes

Create Multiple Folders Using R Codes

Below codes show how to create multiple folders without leaving R environment. The code chunk is useful when, for example, doing graphical diagnostics for some statistical models and numerous (e.g., several hundreds or thousands) diagnostic plots will be produced.  Multiple plots can be woven into a html file, and visually checked afterward.  

foldername <- read.table(nameList.txt, header=FALSE, sep=".")[,1]
 
for(i in 1:length(foldername)){
 tmp <- foldername[i]
 test <- paste("mkdir ", tmp, sep="")
 system(test)
}

Create LVM volume from multiple disks

Create LVM volume from multiple disks

Recently I had to crate an Amazon EC2 Instance with a storage capacity of 5Tb, unfortunately, Amazon only allows us to create 1Tb volumes so I had to create 5 volumes, attach them to the instance and create a 5Tb LVM device.

My instance was running Ubuntu and I hat to install the lvm2 package:

apt-get install lvm2 

The volumes attached to my instance where named from /dev/xvdg to /dev/xvdk

to find the names you can use the command:

fdisk -l

First we have to prepare our volumes for LVM with:

pvcreate /dev/xvdg /dev/xvdh /dev/xvdi /dev/xvdj /dev/xvdk

You can run the following command to check the result:

pvdisplay

The next step is to create a volume group, I used the command:

vgcreate storage /dev/xvdg /dev/xvdh /dev/xvdi /dev/xvdj /dev/xvdk 

And used the command:

vgdisplay

to check the result, you can also use:

vgscan 

Now we need to create the logical volume, in this case I wanted to use the entire available space so, I used the command:

lvcreate -n data -l 100%free storage

And

lvdisplay 

to check the new volume if every thing goes well it should be on /dev/storage/data 

you can also use the command 

lvscan

Now you just have to format the new device, you can use:

mkft -t ext4 /dev/storage/data

When ready you can mount it with:

mout /dev/storage/data /mnt
