Hello,

I own a mono station with an internal 105 meg disk.  I have dedicated the 105  
as a swapdisk according to the instructions in NeXT Answers.  It functions  
properly to a point but will not allow the swapfile to grow above 30 meg.  That  
is my machine generates a number of these errors in /usr/adm/mesgs when the  
swapfile is only 30 megs:  

Nov 14 01:12:12 localhost mach: vnode_pager: /private/swapdisk/vm/swapfile is  
full.
Nov 14 01:18:15 localhost mach: vnode_pager: /private/swapdisk/vm/swapfile is  
available again.

I think that the operating system has even killed processes (preferences often  
dies at approximately the same time) to free up space when this limit is  
reached.  Everything in the swaptab is commented out so no highwater mark is  
set and I assume the swapfile should be able to use the entire disk.  Anyone  
have any ideas what is wrong?  Any help would be appreciated.  I'm using 3.0,  
if it's important.

Thanks,

Michael Ibrahim

It seems that you have the hiwater mark set to 30M in the /etc/swaptab  
file.  Remove the entry for hiwat=xxxxxx and then reboot.  You should then  
be able to use all the disk for swapping.

I had the same problem a few weeks ago.

In /etc, there is a script rc.swap, in which the swapdisk is mounted
to swap on with a highwatermark of 30 Meg. Just change this
highwat=??? to the value, you want.

No, if you have a disk labeled as 'swapdisk', you don't have to fool
around with /etc/swaptab. The information about the high water mark is
in this case in /etc/rc.swap

Gosh, I wish I had YOUR problem! :-)
