From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.5) Gecko/20011012 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): How reproducible: Always 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. Additional info:
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.
