Description Matt Domsch 2001-08-02 21:36:39 UTC

Description of Problem:
Autopartitioning tries to make a swap space that's 2x physical RAM in the 
system.  But, the BOOT kernel can only recognize up to ~880MB of RAM, thus 
autopartitioning makes a swap space of roughly 1.76GB.  If you have more 
than 880MB physical RAM, you then have a swap space that's too small based 
on 2.4.x kernel recommendations.

If >1GB RAM is in the system, and 2x swap is still recommended, then 
multiple swap partitions or swap files need to get created.

How Reproducible:
always

Steps to Reproduce:
1. autopartition with >=1GB RAM in the system
2. 
3. 

Actual Results:
swap space is ~1.8GB

Expected Results:
Swap space would be 2GB or more.

Additional Information:

We cap the swap space we make automatically because it gets absurd to have
16gig of swap on an 8 gig RAM machine, for example.  Our feeling is anyone with
that much RAM will configure the swap themselves since they're probably doing
more than your average desktop-style installation.  7.1 shipped with this cap
and we have not had any reports of problems.

Also the swap requirements of the latest 2.4 kernels are much more relaxed than
the one we shipped in 7.1.

If you like we can make a RFE for the next release to prompt a user if they have
ALOT of RAM and see how they want to autopartition swap for it.

Comment 2 Matt Domsch 2001-08-03 16:28:53 UTC

Agreed it gets absurd, but I hadn't heard that the kernel requirements had been 
relaxed.  RFE for next time would be fine in that case.

Ok.  Deferring until then.
