How to expand SWAP partition on Linux server

I have a new built linux server into which I was going to add RAC cluster. When I was building the system, I didn't pay much attension to the SWAP partition. The partition is only 7887872          kb. Now I need increase it to 16876240  kb, how could I do it?

I checked the free space on the system, it looks like it has some unpartitioned space.

Make new swap

# mkswap /dev/sda?

Disable current swap

# swapoff /dev/sda9

Enable new swap

# swapon /dev/sda?

 and edit swap entry in /etc/fstab

HI, ganjos, thank you for your update.

what partition should I use for the new swap, it looks like all existing partition are too small for the new swap. I need 16876240  kb for the new swap area.

On your command "# mkswap /dev/sda?“ what number should I use to replace "?" sign.

------------------

Besides, I notice I indeed have some unpartitioned area.

from this you know the ending cylinder reaches to 60636,

/dev/sda4           39916       60636   166441432+   5  Extended

But the realistic ending cylinder is 56500. How big is the unpartitioned space? Could I expand the SWAP partition to include this unpartitioned space?  I appreciate your help.

You have extended partition as follow:

/dev/sda4           39916       60636   166441432+   5  Extended

So you should be able to use from 56501 to 60636 as swap, you could add it as /dev/sda11?

I think I can add it as /dev/sda11, what command should I run to extend that partition?

Fdisk?

thank you.

Any help for this?

I want to know if I can delete the existing SWAP partition and merge the space released from this partition with the unused space, then make a brand new bigger SWAP partition. which command should I use?

You can't join sda9 with sda11, because there is sda10, unless sda10 can be deleted.

To delete sda9, disable current swap

# swapoff /dev/sda9

# fdisk /dev/sda9

and delete this partition, then

# fdisk /dev/sda10

if can delete sda10

# fdisk /dev/sda

type "n" for new to create a new partiton, it will be sda9

Make new swap

# mkswap /dev/sda9

Enable new swap

# swapon /dev/sda9

 and edit swap entry in /etc/fstab

Hi, ganjos, thank you for your detail reply.

I am not sure if it's safe to delete sda10.  How could I know /dev/sd10 is used or not?

I indeed found some files on this partition. When I tried to list the parition for the ntpd file under path /etc/sysconfig, it shows the file locates on /dev/sda10 partition. In this case, I don't think I can delete this partition because the OS may not be working after this action. Please advise.


[root@poseidon sysconfig]# df -P ntpd | tail -1 | cut -d' ' -f 1
/dev/sda10

You can try to mount it, ie
# mount /dev/sda10 /mnt
# cd /mnt
# ls

Also if it was in /etc/fstab

# cat /etc/fstab

what I should do now? What the Oracle Cluster requires is the new node should have the same size of SWAP as the existing node. Since I didn't pay too much attention at first when I was installing the OS. Now, it looks hard to change. Could I make a new partition with the unused space and make the second SWAP partition, then make another new SWAP partition?

thanks.

The safe way is forget about sda9, just make a new swap on sda11?

Here is the reply from oracle support.

Hi Jason

You will need to action following on new node:

1. Is this the new home location: "/u1/oracle/11.2.0/gridhome"
2. Set the swap to required settings as per Installation guide
3. Start ntp with -x option
4. Fix parameter rmem_default to same as on existing nodes:

Compatibility check: Kernel param "rmem_default" [reference node: elysium]
Node Name Status Ref. node status Comment
------------ ------------------------ ------------------------ ----------
poseidon 262144 4194304 mismatched

Sorry I can't help you with what oracle support already told you, but I think I have answered your question "How to expand SWAP partition on Linux server".

Basicly what I can see that you still have 4 times of the current swap space free for what ever you want to use including new swap.

Could I make another new SWAP partition which made me have two SWAP partition totally?

Please advise. I really want to learn how I could make this feasible.

You could simply add anther swap, ie

Partition sda11 with

# fdisk /dev/sda

Make new swap

# mkswap /dev/sda11

Enable new swap

# swapon /dev/sda11

 and edit swap entry in /etc/fstab

thanks, when I am doing the first step, it asks for beginning and ending cylinder number. what number should I use for the ending cylinder if I want to add 8988368 kb SWAP space.

The present SWAP area on this server is 7887872 kb, I need increase it to 16876240 kb, how could I do the calculation? I am a newbie in linux world, and really appreciate your help.   Thank you very much.

I think 82 is the type of the partition, but what is the "Last Cylinder" I need input to make the size a specific size?

I want to create a new SWAP partition with t a specific size of 8988368kb, with the existing SWAP partition of 7887872kb which make the total of 16876240kb.

for the above /etc/fstab file, I commented out the old swap definition line and added a brand new line, I guess there is something wrong here.

what is interesting is when i use "free -k" command to show the swap area, it indeed changed to the value I want to.

I couldn't see it has been definded, if it was, the "p" command should show the partition start and end points, but you output showed nothing, see below.

Command (m for help): p

for some reason,  it is showing up now.


[root@poseidon 11.2.0]# fdisk /dev/sda

The number of cylinders for this disk is set to 60636.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
   (e.g., DOS FDISK, OS/2 FDISK)
