Description of problem:
The installer does not do proper checks on available disk
space before starting an "upgrade".
Version-Release number of selected component (if applicable):
Steps to Reproduce:
Try to upgrade from redhat-6.2 to redhat-7.2 on disk with about 1 Gbyte
of free disk space.
Actual Results: Upgrades to redhat-7.2 fail with "unsufficient disk space"
errors after the extremely time consuming "preparing to install" progress
bar. I had two failures out of two upgrades- one being 23 Mbytes short on
disk space (on a 12 Gbyte disk with 1 Gbyte free before
the upgrade), the other 10 Mbytes short. This is ridiculous.
Expected Results: The installer should:
1) make it clear how much space is available and how much is
needed, in the package selection screen.
2) warn that there is not enough space *before* going through the
painfully slow "checking package dependancies" and
"preparing to install" phases.
3) include a reasonable margin of error, to avoid silly
"short 1 Mbyte out of 5 Gbytes of disk space" failures.
4) if there is not enough space, automatically offer the user
to unselect some packages.
This will require substantial changes to the way the upgrade process works.
Will revisit for a future release.
I have had this very problem upgrading my laptop from FC1 to FC3. The
installer said I needed 526MB more room on /. But to my knowledge,
there was plenty of room on the drive.
