Hi all i wonder that what is arraning, managing swap size...

Today i need to resize Swap size but didnot fount anyting about that..

My swap size is this. Already Mounted.
Code: 
Device          1K-blocks     Used    Avail Capacity
/dev/ad14s1b      4194304        0  4194304     0%

Before
Code: 
CPU: 41.5% user,  0.0% nice, 19.7% system,  1.3% interrupt, 37.5% idle
[color="Red"]Mem: 3110M [/color]Active, 4262M Inact, 185M Wired, 210M Cache, 112M Buf, 236M Free
Swap: 4096M Total, 4096M Free

After
Code: 
CPU: 41.5% user,  0.0% nice, 19.7% system,  1.3% interrupt, 37.5% idle
[color="Red"]Mem: 3110M Active[/color], 4262M Inact, 185M Wired, 210M Cache, 112M Buf, [color="Red"]2236M Free[/color]
[color="Red"]Swap: 2048M Total, 2048M Free
[/color]


What should i do for resizeing swap space?
 
Your question and the info you posted doesnt seem very clear to me.
The info posted shows that you had 4GB swap and have reduced it to 2GB, and also shows that the swap devices is 4GB (but doesnt say if this is before or after).

What exactly did you do, what are you trying to achieve? Does the output of swapinfo match the current size of your swap device?

thanks Andy.
 
When i type top swap size is this
Code: 
Swap: 4096M Total, 4096M Free
But I use only 2048 swap size. How can I arrenge this any way?

You see my real
Code: 
Mem: 3110M Active, 4262M Inac
I need real memory 4x2G Ram slot I got Mother bord dont supoort 4x4G ram.


Code: 
CPU: 48.7% user,  0.0% nice, 22.4% system,  1.5% interrupt, 27.4% idle
Mem: 3170M Active, 4169M Inact, 235M Wired, 92M Cache, 112M Buf, 337M Free
Swap: 4096M Total, 4096M Free
 
The "before" top output shows a total of 8GB of RAM. The "after" top output shows a total of 10GB of RAM.

The numbers don't add up.
 
hımm any clue? for the swap size how you manage this.

Ä°f i use 2048 Swap size i thing my real memory grow up 6G Ram so Free space will be greater then this value now i only have 273 free space when show under 200 system panics.

1) Your swap size will NOT be added to real memory. Because it is not normal. Swap is different thing than RAM.
2) Its nothing bad when you have only 273 free ram. Most of RAM used for buffers, cache etc. And will be freed when OS will need this memory for programs.

No, the Mem: bit in top only shows REAL memory aka RAM. It does not include virtual memory.

Not only that. He wants to take 2G from swap and add to (physical) free memory.
(Before is the current state, After is what he's looking to accomplish).
 
It really is too bad that there's not enough documentation about BSD. Also, that there's so little water in the oceans.
