Description Andre Robatino 2012-08-16 11:27:05 UTC
Description of problem:
On the F17 install discs, the rd.live.check boot option triggers a mediacheck. You can actually see it checking the disc, and if it fails, the installer drops to a dracut prompt. On 18 Alpha TC2 (and probably TC1 as well) this doesn't happen. There is no visible sign of a mediacheck, and even if the image is corrupted, so that checkisomd5 fails, the installer boots.

Version-Release number of selected component (if applicable):
18 Alpha TC2 (either i386 or x86_64, either DVD or netinst)

How reproducible:

Steps to Reproduce:
1. Try to replace the minimum amount of the end of the ISO with zeroes in order to get checkisomd5 to FAIL. For example "truncate -s 270910K Fedora-18-Alpha-TC2-i386-netinst.iso", then "truncate -s 277872640 Fedora-18-Alpha-TC2-i386-netinst.iso".
2. Boot from the ISO with the rd.live.check option (default for the install discs).
Actual results:
Installer boots same as usual.

Expected results:
Some visible sign of a mediacheck, and installer should drop to a dracut prompt if it fails.

Still broken in 18 Alpha TC3.

Comment 2 Andre Robatino 2012-08-31 08:48:37 UTC
Still broken in 18 Alpha TC4.

Comment 3 Andre Robatino 2012-09-01 04:25:01 UTC
Still broken in 18 Alpha TC5.

Comment 4 Andre Robatino 2012-09-06 19:29:06 UTC
Still broken in 18 Alpha TC6.

Comment 5 Xavier Hourcade 2012-09-08 21:22:22 UTC
Also applies to Live CD iso (tested Live KDE alpha TC5 & TC6 here)

Comment 6 Andre Robatino 2012-09-11 01:38:07 UTC
Still broken in 18 Alpha RC1.

Comment 7 Harald Hoyer 2012-09-11 10:47:04 UTC
Anaconda's way of dracut handling does not work with the livecd mediacheck in dracut.

anaconda calls /sbin/dmsquash-live-root with the image path, but the mediacheck in dmsquash-live-root wants a block device.

Comment 8 Andre Robatino 2012-09-11 20:52:55 UTC
Still broken in 18 Alpha RC2.

Comment 9 Chris Lumens 2012-09-11 20:54:00 UTC
No work has been done on this yet, so yeah.  We know.  We don't need a day-by-day update.

Comment 10 Adam Williamson 2012-10-24 01:57:58 UTC
This has been silently proposed as a Beta blocker, but I think Final is appropriate according to the criteria: "If there is an embedded checksum in the image, it must match. If there is a related UI element displayed after booting the image, it must work and display the correct result" is a Final criterion.

So I'm -1 Beta blocker, probably +1 Beta NTH.

Comment 11 Adam Williamson 2012-10-24 16:43:15 UTC
Discussed at the 2012-10-24 blocker review meeting: http://meetbot.fedoraproject.org/fedora-qa/2012-10-24/f18beta-blocker-review-5.2012-10-24-16.01.log.txt . Agreed this is rejected as a Beta blocker, accepted as a Final blocker per criterion cited above, and accepted as Beta NTH as it's obviously worth fixing for Beta post-freeze.

Comment 16 Andre Robatino 2012-11-03 06:36:27 UTC
The mediacheck appears to work properly on all four 18 Beta TC7 (anaconda 18.24) install discs now (prints PASS when okay, prints FAIL and drops to an emergency prompt when not). However, there is no longer a progress indicator, so the check on large optical media may cause the user to think the installer is hung, rather than busy. Is it possible at all to include one?

Comment 17 Andre Robatino 2012-11-03 08:37:41 UTC
The mediacheck on live images (in the Troubleshooting menu) does not appear to give any visible indication at all of its running, not even a PASS or FAIL. I did verify that a FAIL causes it to drop to an emergency prompt, though.

Comment 18 Andre Robatino 2012-11-03 08:40:07 UTC
Sorry, should have said that the live image mediacheck does not give any visible indication for PASS. It does print error messages including FAIL when it drops to an emergency prompt.

Comment 21 satellitgo 2012-11-07 21:13:05 UTC
Default menu (line2) in grub of smoke15 DVD has about a 3 minute pause: 

"[ok] reached target basic system"

in boot of anaconda
This appears like a hang of the installer
a progress bar (or message that disk is being checked) would be nice here

Use of first line of grub does not have this delay

Comment 22 Adam Williamson 2012-11-08 09:29:47 UTC
18.26 went stable. Closing. (Bodhi closing of bugs when updates go stable is currently broken). (verified in comment #16; please file requests for progress display etc as new bugs).

Comment 23 Andre Robatino 2012-11-08 10:06:06 UTC
Filed bug 874486 (RFE: progress indicator for mediacheck so users know the installer isn't hung).
