Description Fred J. Tydeman 2012-03-17 05:26:00 UTC

Description of problem:
Cannot install to a '/' partition smaller than 4096 Meg

Version-Release number of selected component (if applicable):
Fedora Core 17 alpha Live CD

How reproducible:
Always

Steps to Reproduce:
Downloaded the alpha Fedora Desktop Live Media via an existing FC15 system.  Used Fedora LiveUSB creator to put it on a USB memory stick.  Booted that USB memory stick.  Ran Install to hard disk.  Picked a custom disk layout to use a 2008 meg swap partition and a 4016 meg '/' partition.  That gets an error that '/' must be at least 4096 meg.

Please turn that hard error into a warning and let me continue with the install.

Cylinders/Heads/Sectors that different OSes would like:
C/H/S */240/63 = OS/2, eCS and older Windows
C/H/S */255/63 = Linux

Since 240 = 15*16 and 255 = 15*17, the number 15*16*17 is the magic
number of C/H to use for partitions.  Since each head is 63 sectors,
and each sector is 512 bytes, 15*16*17*63*512 works out to 125.5 meg.
Therefore, if every partition is a multiple of 125.5 meg, each
partition will appear to be on a cylinder boundary to OS/2, eCS, all older
Windows, and Linux.

125.5 meg * 32 = 4016 meg is the size of partitions I use for Linux.
I use partitions of size 1004, 2008, 4016, 16064 meg.

The last time I hit this problem, I installed the SOAP desktop version of Fedora Core (since it installs to a smaller '/' partition), and then added the gnome desktop.

Actual results:
A hard error about a small '/' partition that stops install.

Expected results:
A warning about a small '/' partition and then let me continue with the install.

SOAP in the above should be SOAS (Sugar on a Stick)

Comment 2 Chris Lumens 2012-03-19 17:51:04 UTC

We don't do anything with CHS here.  We run a program to determine how big the live image is, and get a size back in MB.  We then check that against how big you've decided to make the drive.  Turning this into a warning is just going to lead to us getting weirder bugs in the future from people who choose to ignore it and continue on.
