_____________________________________________________________________________

you can install linux on single partition. That is /.

It is better to make 3 partition.

/

/swap

/boot

But recommended to make 7 partition, That are .......

 

/  (The root file system is represented by a forward slash (/), it is father of the file system.)

/swap

/boot

/home

/usr

/var

/tmp

CentOS 6.4 64 bit. It required /boot/efi or it won't proceed

 

deletion of partition

I have one query, when we delete the partition is it necessary to reboot the server or we can use partprobe -s???

Need ur help guys.

 

___________________________________________________________________________________

partprobe -s is enough. This command re-reads the partition table.

When you restart the server then also the same thing happens. The partition table is read to check if any changes has happened.

 

_________________________________________________________________________________

 

If we reboot the server then it will become "Microsoft Linux"  :)  . No need to reboot the server ...

 

______________________________________________________________________________

 

Deleting partition can be done online.

 

/ Partition is showing 100 %

In one of server / partition is showing fully utilized 100 %, I have checked manually all the directories in it, but none of the data is there. I have rebooted the server & also run fsck on the / partition, but no luck.

Can anyone help me to resolve this problem( / is not in LVM).
