how to increase my swap area while...

how much swap do you want? the basic idea is to create a file of the size you need, and then add it as a swap file

you would do something like this

sudo dd if=/dev/zero of=/swap1.swp bs=1024 count=1048576
sudo swapon /swap1.swp

that would add a 1 gb swap file

abed@abed-laptop:~$ sudo dd if=/dev/zero of=/swap1.swp bs=1024 count=1048576
[sudo] password for abed:
1048576+0 records in
1048576+0 records out
1073741824 bytes (1.1 GB) copied, 27.0363 s, 39.7 MB/s
abed@abed-laptop:~$ sudo swapon /swap1.swp
swapon: /swap1.swp: Invalid argument
abed@abed-laptop:~$ sudo swapon /swap1.swp
swapon: /swap1.swp: Invalid argument
abed@abed-laptop:~$

dude i believe the first line went sweet but the second command!!!!

and can u explain it for me ? even the numbers??

[coopstah13]

sorry i made a booboo
it should be

sudo swapon -a /swap1.swp

bs=1024, this is specifying a block size of 1024 bytes or 1 kilobyte
count=1048576

this is how many blocks you want to have the file to be, 1048576 blocks * 1024 bytes/block = 1 gigabyte

thnx bro u were helpful thnx
and about my first command line did u go well?

[kmitnick]

abed@abed-laptop:~$ sudo swapon -a /swap1.swp
swapon: /swap1.swp: Invalid argument
abed@abed-laptop:~$

dude wut's wrong?

[coopstah13]

sorry, i was just kind of making it up as I went hoping it would work

gksu gedit /etc/fstab

add this to the end of fstab file

/swap1.swp       none            swap    sw              0       0

then run

sudo swapon -a

I've only added swap file on running solaris, i hope this works this time
