Description Bryn M. Reeves 2007-06-26 11:33:52 UTC
Description of problem:
The diskdumputils README has a lengthy section on formatting the device for
diskdump use, including the following paragraph:

    When you see the above message but want to format them as dump-dedicated
    devices, follow the instructions below.
    First, disable the swap partition with swappoff, or unmount the partition
    with umount.  Then, run the command below.

     # diskdumpfmt -f <device>

Although this mentions using dump-dedicated devices, it leaves it unclear as to
whether devices that are used for both swapping and dumping should also be
formatted in this way (they shouldn't).

This causes confusion & gives the impression that shared swap/dump devices don't
work when in fact they are fine.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Read /usr/share/doc/diskdumputils-1.3.25/README
Actual results:
No exact steps for configuring shared devices are present, nor is there a clear
comment that the diskdumpfmt step is not needed in this case.

Expected results:
Clear instructions for either case.

Hi Bryn,
