Unable to change Desired Capacity of system after resizing swap with BTRFS
Last modified: 2016-09-19 22:45:03 EDT
Description of problem:
After doing automatic partitioning with BTRFS, I am unable to shrink the swap and resize my system to utilize the extra space. This does work with LVM, however.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Choose BTRFS, review/modify configuration, and click automatic partitioning
2. Shrink the swap partition
3. Attempt to change the Desired Capacity of your system or home partitions
The Desired Capacity field is disabled.
You should be able to give the extra space to your system, just like you can with LVM.
The btrfs subvolumes are all part of the same btrfs volume. As a result, they have no size of their own -- there is only the size of the volume. To edit the volume, select any of the btrfs mountpoints and then click the Edit or Modify (I forget which it is) button on the lower right hand side of the options area on the right side of the screen. A dialog will appear which includes options for setting the btrfs volume's size. You might need to change it "As large as possible" and then click the "Update settings" button once you are back to the main screen.
Let me know if that does not get you the desired result.
Yes, that looks like changing the size policy does the trick, thanks.

I've found one problem with that ... even having set the size to "As large as possible", the displayed size does not change
could that be fixed so that after e.g. shrinking the swap the size displayed for btrfs mountpoints increases when the volume is set to anything else than "Fixed"?
This message is a notice that Fedora 19 is now at end of life. Fedora
has stopped maintaining and issuing updates for Fedora 19. It is
Fedora's policy to close all bug reports from releases that are no
longer maintained. Approximately 4 (four) weeks from now this bug will
be closed as EOL if it remains open with a Fedora 'version' of '19'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.
Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 19 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
Fedora 19 changed to end-of-life (EOL) status on 2015-01-06. Fedora 19 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
