                        #SWAP INCREASING WITH MAKING PARTITION #

POINT: -------NOW IF WE INCREASE OUR RAM THEN WE HAVE TO INCREASE THE SWAP ALSO FOR      1_____FOR THIS WE HAVE TO MAKE A LOGICAL PARTTITON FIRST.                        

            2_____THEN MAKE IT THE SWAP WITH FORMATING IT IN SWAP.

            3____ ALSO HAVE TO CHANGE ITS ID.

WE KNOW SWAP IS ALWAYS THE DOUBLE OF THE RAM.                                                                                             4____THEN MAKE A PARTITON THE DOUBLE OF YOU ADDED THE SIZE OF THE RAM.

5____THEN SAVE THE PARTITON OF NEW LOGICAL DRIVE.

6____THEN CHANMGE THE ID OF THE PARTITON B COZ THE SWAP AND LOGICAL HAVE

          DIFFERENT ID`S

           

                        PARTITON                ID

                       

                        LOGICAL                  83                                                                                                                                SWAP                         82

7____AFTER CHANGE THE ID FORMAT IT IN THE SWAP.

8____NOW ACTIVATE IT BY GIVE THE LINK IN THE [/etc/fstab] FILE.

       

  

ALSO REMEMBER TO REFRESH THE MOUNTING POINT AFTER MAKE THDE PARTITION.                                    

           

NOW HOW TO MAKE THE SWAP PRACTICALLY___________________________________________

SUPPOSE RAM      SWAP       AFTER INCREASE   RAM          SWAP TO BE INCREASE

  1 GB                                     2 GB                                           1 GB                       2 GB

YOU HAVE TO INREASE THE SWAP DOUBLE OF ADDED RAM.,

            # fdisk –l ______ to show the partitions.

            # fdiisk /dev/sda ___to enter in the mode to make a new partition

            (Command (m for help) n ______________enter

            To make a new partition . then  make a partition of size you want.

            (Command (m for help) w_______________enter 

            To save the partition.  

            (Command (m for help) t _______________enter

            To change the partition id  

          Partition no ____(1-6) --    give here no of which partition u want to change the id .

            Partition id ____------____give the partition id you want to give (give here partition id 82)

swap has id (82).

Now format the partition in swap ________________________________________

# mkswap /dev/sda6 ______ to format in swap file system.

Then the following steps_______________________________________________

# rm –rf  /dev/fd0 ____ to disable floppy drive .

#partprobe _________to refresh MBR.

Now to activate swap _______________________________________________

# swapon /dev/sda6 _______ now swap is active  now make its mounting permanent.

MOUNTING______________________________________________________

# vi /etc/fstab   ___________to open fstab .

Enter the following  link in FSTAB.

/dev/sda6       swap               swap   defaults          0 0 .

:wq __enter to save n exit from FSTAB.

Now _____________________________________________________________

# mount –a _____ to refresh mounting point.

# swapon –s ____ to check the active swap now .
