pokusao sam nesto ovako, moguce je da sam izostavio neki korak, pa bih da upitam za pomoc.

dd if=/dev/zero of=/dev/hda2 bs=1024 count=262144
mkswap /dev/hda2 262144
sync
swapon -a

i onda swapon -s vraca:
Filename Type Size Used Priority
/dev/hda2 partition 262136 0 -3


i kako pokusavan iznova Priority sve vise ide u minus. Inace, distribucija je Slackware 10

anyone? :)

Pa sve je ok - ako ti je to jedini swap prostor, priority ti nije ni bitan. Ako ti treba rucno setovanje prioriteta, swapon ima -p i jos neke parametre pa probaj sa time.

gojko brz si ko munja :)

-p priority

Specify priority for swapon. This option is only available if swapon was compiled under and is used under a 1.3.2 or later kernel. priority is a value between 0 and 32767.

dobro ako ti tako kazes, verujem... mada ovo ogranicenje 0-32767 mi ipak ne da mira..

Mislim da je taj priority slican onom niceness-u procesa - ako svi imaju isti priority ili ako je samo jedan proces (tj. u ovom slucaju swap prostor) u pitanju, onda priority i nema nikakvog uticaja. Moze da bude i low priority prostor ali ako je jedini - samo njega ce i koristiti.

Citat:
Each swap area has a priority, either high or low. The default prior-
ity is low. Within the low-priority areas, newer areas are even lower
priority than older areas.

All priorities set with swapflags are high-priority, higher than
default. They may have any non-negative value chosen by the caller.
Higher numbers mean higher priority.

Swap pages are allocated from areas in priority order, highest priority
first. For areas with different priorities, a higher-priority area is
exhausted before using a lower-priority area. If two or more areas
have the same priority, and it is the highest priority available, pages
are allocated on a round-robin basis between them.

As of Linux 1.3.6, the kernel usually follows these rules, but there
are exceptions

To pise u man-u, nego ne vidim da se spominje slucaj kada imamo samo jedan swap prostor?
[ markom @ 08.11.2004. 11:08 ] @
Onda je, kao što se može skučiti iz napisanog u manu, irelevantno koji je priority pošto nema sa čim da se uporedi da li je veći ili manji... Jedino treba malo voditi računa ako se doda još jedan swap ...

u svakom slucaju, najbolje bi bilo da to pise u man-u i razbije sve sumnje...
