Red Hat Bugzilla – Bug 848764
default mediacheck on 18 Beta TC6 discs does not work
Last modified: 2012-11-08 05:06:06 EST
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)
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).
Installer boots same as usual.
Some visible sign of a mediacheck, and installer should drop to a dracut prompt if it fails.
Still broken in 18 Alpha TC3.
Still broken in 18 Alpha TC4.
Still broken in 18 Alpha TC5.
Still broken in 18 Alpha TC6.
Also applies to Live CD iso (tested Live KDE alpha TC5 & TC6 here)
Still broken in 18 Alpha RC1.
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.
Still broken in 18 Alpha RC2.
No work has been done on this yet, so yeah. We know. We don't need a day-by-day update.
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.
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.

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?
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.
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.
anaconda-18.25-1.fc18 has been submitted as an update for Fedora 18.
anaconda-18.26-1.fc18 has been submitted as an update for Fedora 18.
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
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).
Filed bug 874486 (RFE: progress indicator for mediacheck so users know the installer isn't hung).
