F9=>F10 preupgrade hangs at "Generating metadata 18%"
Last modified: 2014-01-21 18:08:46 EST
Description of problem:
On a machine with a lot of packages (1139), trying to upgrade a fully-upgraded F9 installation to F10 using preupgrade.
It runs through without problem until it gets to "Prepare and test upgrade" section where it hangs every time at "Generating metadata 18%".
In the terminal window it shows Missing dependencies for:
There is 80GB of space available for install. Says 500MB required.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. fully update an F9 installation
2. run preupgrade
3. select F10
installs F10 successfully
I just noticed on the machine above that the md raid is syncing an array. And I had noticed one other time that you can get weird hangs when there is array syncing going on and you have lots of disk activity. So I'll wait until this array is synced and then try the preupgrade again.
The missing dependencies are not important - we ignore them and so does anaconda.
Unless there's a traceback on the console (or in ~/.xsession-errors) this is probably just a disk IO problem.
Can you reproduce this when you're not in the midst of an mdraid sync? Is there a traceback?
I tried this 3 times with the array syncing and each time preupgrade would hang at the Generating metadata point.
I then tried preupgrade after the mdraid array was finished syncing and then preuprade completed with no problem.
Just a little more evidence that mdraid syncing has some vulnerabilities.
Please close the bug. Not a preupgrade problem.
