[Bug 483136] New: boot fails with cmdline root=LABEL= syntax (could not find /dev/root)
https://bugzilla.novell.com/show_bug.cgi?id=483136 Summary: boot fails with cmdline root=LABEL= syntax (could not find /dev/root) Classification: openSUSE Product: openSUSE 11.2 Version: Alpha 0 Platform: i586 OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: Kernel AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: mrmazda@ij.net QAContact: qa@suse.de Found By: --- Created an attachment (id=277819) --> (https://bugzilla.novell.com/attachment.cgi?id=277819) tgz of current & prior /var/log messages & boot.msg User-Agent: Mozilla/5.0 (OS/2; U; Warp 4.5; en-US; rv:1.8.1.19) Gecko/20081212 SeaMonkey/1.1.14 (PmW) Current kernel is 2.6.29-rc6-git1-2-pae, but this has been going on with several kernel upgrades since before Christmas. Boot halts with "waiting for device /dev/root to appear ... could not find /dev/root ... want to fall back to /dev/dev/disk/by-id/...part10". On answering y, boot proceeds normally. Previously working cmdline kernel /boot/vmlinuz showopts root=LABEL=S16A-10factory causes above message. If I replace root=LABEL=S16A-10factory with root=/dev/sda10 then boot proceeds normally. This is my bug 397816 P4/ICH4 (Dell GX260) system, which has been on ata_piix and dm_linear for the 11.1 Factory. I've tried my best to eradicate dm_linear support for the / (only) HD in 11.2 Factory, as described in http://lists.opensuse.org/opensuse-factory/2009-02/msg00335.html thread, but this problem has survived my attempt to (possibly successfully) convert. Reproducible: Always Steps to Reproduce: 1.Try to boot using root=LABEL= cmdline syntax Actual Results: Boot halts Expected Results: Boot proceeds normally Looks a lot like bug 300550 . When I boot a very old 2.6.24 11.0 Factory kernel and initrd with piix /, boot proceeds normally, with / mounted on /dev/hda10. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Hi, root=LABEL=something is bad syntax
If this is "bad syntax", it is a recent regression. It should remain an alternate syntax. During the late stages of 11.1 development it continued to work as it did in 11.0, 10.3, 10.2 & probably before then. I have been using this syntax for booting all my Linux distros (*buntu, Mandriva, Fedora, openSUSE) for two years or more: 00srv:~ $ cat /etc/SuSE-release openSUSE 11.0 (i586) VERSION = 11.0 00srv:~ $ uname -r 2.6.27.7-10-pae 00srv:~ $ cat /proc/cmdline root=LABEL=08-suse110 noresume splash=off vga=0x305 3 00srv:~ $ tune2fs -l /dev/sda8| grep ume Filesystem volume name: 08-suse110 FWIW, some months ago I stopped booting from the Grub installed by the selected distro. I install Grub to the / partition, but but boot from a primary partition that does not bet mounted to /boot. The menu.lst on the real boot partition., which by convention I mount to /disks/boot, I manage myself. Until now, everything has been booting using root=LABEL= syntax.
correct is root=/dev/disk/by-label/something ...
That may be what the installer does now, but at least as recently as November's Factory YaST was still using root=LABEL= syntax here. Long strings may be fine for GUI puter applets to manage, but they're not so good for normal human brains or for fitting on a single viewport-length line while editing a config file.
I cannot reproduce it if I install 11.1 and mount by label...could you please specify what you do?
I've done no fresh installs in many months, waiting for a post-2.6.27 installation kernel so that I can install on libata onto whichever partition up to #63 I please. Other than specifying to mount by label to my pre-existing and pre-labeled partitions during installation, I don't remember doing anything more than written above that deviates from defaults.
or please attach yast logs, maybe it still have logs about this change. Thanks
Most of my updating gets done via cmdline zypper.

Reassign it to kernel guys. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
