Swap - Reserve

[Tom Dawson]

Hi,

I have the following swap configurations:

flor flo1q05 / # swapinfo
Kb Kb Kb PCT START/ Kb
TYPE AVAIL USED FREE USED LIMIT RESERVE PRI NAME
dev 524288 18960 505328 4% 0 - 1 /dev/vg00/lvol2
dev 524288 18228 506060 3% 0 - 1 /dev/vg00/lvol4
reserve - 490460 -490460

Can someone tell me if I understand this correctly. Does the 490460 Kb of reserve tell me that the programs running, or waiting to run, would take up a total of 490460 Kb of RAM if they were all in there at once?

Thanks,
Tom

Tom,

man swapinfo:

reserve: Paging space on reserve. This is the amount of paging space that could be needed by processes that are currently running, but that has not yet been allocated from one of the above paging areas. See "Paging Allocation" below.
