Description Matthieu Araman 2009-04-13 19:07:53 UTC

Description of problem:


Version-Release number of selected component (if applicable):
boot.iso 20090404
see parent bug for detail about hardware

How reproducible:


Steps to Reproduce:
1. install with LVM + RAID + ext4 (custom partitionning), 2 1To Drives mirrored
2.
3.
  
Actual results:
interface is not very responsive
formatting takes forever (>30 min)
console shows many message about raid

Expected results:
/dev/md0 contains /boot on ext3 -> should be forced synchronized before allowing the user to reboot
/dev/md1 should be resynchronized in background
ext4 use prefetch -> formatting should be very fast
the whole should take only a few seconds/minutes
As drives get cheaper, I think it's important to correct this.

Additional info:
I think it's a regression as with boot.iso from March, results were very fast 
As I could never finish installation correctly with LVM + Raid, I can't really conclude ...

Can you pls attach logs from the installation.  They are located in /tmp/* while you are installing.

Comment 2 Matthieu Araman 2009-04-26 11:26:31 UTC

Just retested with boot.iso 20090424/anaconda-11.5.0.47-1
This now works correctly except for progress bar (see bug 497701)
Takes about 1 minute for all the formatting to occur which is a great improvment as I've got two 1To disk and it would take a lot more time in ext3 times...
