Description of problem: Because NTFS resize support isn't something we control, and is considered by installer and QA teams to be a "best effort" scenario, we should have a gate keeper dialog that suitably conveys the resize risk to the user and encourage them to use Windows to do the resizing, then come back to Fedora to install into the resulting free space. Following the user acknowledging this message, they'd be permitted to use built-in resize functionality. (Unless the installer team prefers to drop NTFS resizing support, which I would definitely not blame them for.) Version-Release number of selected component (if applicable): anaconda-22.x Current results: User isn't informed of risks associated with NTFS resizing. Expected future results: User should be aware it's not risk free. There's no assurance the user knows this in advance. Additional info:
See also bug 1134142. After resizing a Windows 8 NTFS volume, upon rebooting Windows 8 it doesn't automatically chkdsk /f like Windows 7 does after an ntfsresize. If it turns out the user should manually intervene, it seems both Fedora installer devs and user are better off being advised to do the resize in Windows. It's kinda convoluted doing this in anaconda, then having to figure out how to initiate startup repair or chkdsk /f manually. And multiple reboots.
"ntfsresize - resize an NTFS filesystem without data loss" I dunno, sounds good to me.
