Description Shyam Mani (RETIRED) gentoo-dev 2004-10-25 03:07:28 UTC
I emerged baselayout-1.11.3 (as part of emerge -uD world) and then did an etc-update. When I rebooted, I got :

*Checking root Filesystem...   [ok]
Failed to open the device '/dev/hda5': No such file or directory

*Filesystem couldn't be fixed :(   [!!]
Give root password for maintanence
(or type Control-D for normal startup):

I booted into FC2, chrooted to roll back to baselayout-1.10.4 and things were fine. Once back into Gentoo, I tried updating to 1.11.3 (thinking I messed up somewhere) but ended up with the same above mentioned error(s).

Any other piece of info that maybe useful?
Comment 1 David Bruha 2004-10-25 04:28:03 UTC
Same here. Had to rollback to 1.10.4.
Comment 2 Jos Delbar 2004-10-25 05:04:35 UTC
Same problem here. For some reason, the fsck calls in /etc/init.d/checkroot and /etc/init.d/checkfsnow now fail. After entering sulogin, I found no hda entries in /dev, maybe that is the problem?

Comment 3 Shyam Mani (RETIRED) gentoo-dev 2004-10-25 05:06:18 UTC
Yeah. /dev had no entries for hdx. I guess that's the only reason the fsck fails? Coz there is nothing to check as far as it can see...
Comment 4 SpanKY gentoo-dev 2004-10-25 06:07:04 UTC
do you guys all use udev ?  what do you have RC_DEVICES set to in /etc/conf.d/rc ?

if so, do you use the RC_DEVICE_TARBALL feature ?
Comment 5 Shyam Mani (RETIRED) gentoo-dev 2004-10-25 06:10:44 UTC
I don't use udev.

I don't seem to have RC_DEVICES in /etc/conf.d/rc but I do have RC_DEVICE_TARBALL set to yes.
Comment 6 SpanKY gentoo-dev 2004-10-25 06:24:15 UTC
umm, if you're using 1.11.x and you dont have RC_DEVICES in /etc/conf.d/rc, it sounds like you either didnt run `etc-update` or portage didnt merge all the config files correctly

if `etc-update` doesnt show anything to update, try `emerge baselayout --noconfmem`
Comment 7 Shyam Mani (RETIRED) gentoo-dev 2004-10-25 06:28:15 UTC
I'm using 1.10.4 now. You want me to retry with 1.11.3? 

PS : etc-update showed 26 files to update (after merging 1.11.3) & I'm pretty sure /etc/conf.d/rc wasn't one of them...maybe its not updating /etc/conf.d/rc as it should?
Comment 8 David Bruha 2004-10-25 06:34:39 UTC
Created attachment 42557 [details]
/etc/conf.d/rc

/etc/conf.d/rc was actually updated while doing rc-update to this ...
Comment 9 Shyam Mani (RETIRED) gentoo-dev 2004-10-25 06:36:46 UTC
Possible then that auto isn't doing its job? I have devfsd...
Comment 10 César Fernández 2004-10-25 06:47:40 UTC
People using udev (/me use udev) say the solution is set RC_DEVICES="udev" instead of "auto"... 

Or maybe just a Device Tarball = yes ?
Comment 11 barthek 2004-10-25 06:58:45 UTC
I have set RC_DEVICES to "devfsd" (i use dev fs)
with no luck at all - system won't boot...
Comment 12 Daniel Jasper 2004-10-25 07:05:16 UTC
Same problem here. Happens with RC_DEVICES set to "auto", "devfs" and "udev". However if I replace /dev/hdaX in /etc/fstab with /dev/discs/disc0/partX, then everything is fine again. After the successful boot I again have /dev/hda*.
Comment 13 Lim Swee Tat (RETIRED) gentoo-dev 2004-10-25 07:19:26 UTC
You need to edit /etc/fstab to use /dev/ide/host0/bus0/target0/lun0/partX instead of hdaX
Comment 14 David Bruha 2004-10-25 07:35:59 UTC
By that you are just working around the problem of not created /dev nodes.
Comment 15 Simone Gotti (RETIRED) gentoo-dev 2004-10-25 07:42:41 UTC

Comment 16 SpanKY gentoo-dev 2004-10-25 07:46:47 UTC
sounds like the auto setup is selecting devfs instead of udev like it should

when the system is booting, what do the init scripts say for setting up /dev ?
Comment 17 gentoo 2004-10-25 07:52:32 UTC
solution: 
/sbin/devfsd /dev

in start section of etc/init.d/checkroot
Comment 18 SpanKY gentoo-dev 2004-10-25 07:56:19 UTC
/sbin/rc already runs devfsd:
                ebegin "Starting devfsd"
                /sbin/devfsd /dev > /dev/null
                eend $? "Could not start /sbin/devfsd"

right after it mounts devfs on /dev:
                ebegin "Mounting devfs at /dev"
                try mount -n -t devfs none /dev
                eend $?

so forcing it to run in checkroot may be one hack of a workaround but it isnt a solution
Comment 19 Stephan 2004-10-25 08:49:33 UTC
same here chrooted and falling back...
Comment 20 Cubittus 2004-10-25 11:25:19 UTC
I use devfs and had this problem on reboot.

I found that /sbin/rc checks if /dev/.devfsd exists to determine whether devfsd
is already running but on my system it seems to be there before devfsd is started.  I don't know where it is coming from though.  devfs is compiled into the kernel (2.4.26).
Comment 21 SpanKY gentoo-dev 2004-10-25 11:46:54 UTC
ok, as Cubittus points out, the problem seems to be with people who use
devfsd and have it compiled into their kernel to automount at boottime

i'll test out that configuration and work with agriffis to release either
a 1.11.3-r1 or 1.11.4
Comment 22 Chris Smith 2004-10-25 11:59:09 UTC
It's not just devsd users. I use udev here and had to drop back to 1.10.
Comment 23 SpanKY gentoo-dev 2004-10-25 12:46:30 UTC
everyone please post this info then:

what do you normally use (udev/devfs) ?
what do you have RC_DEVICES and RC_DEVICE_TARBALL set to ?
during bootup, what do you see after 'Mounting proc at /proc' and before 'Activating (possible) swap' ?
when you sulogin, what does /proc/mounts show ?
there's probably multiple issues here, but the devfs one is due to /sbin/devfsd not being started when devfs is auto-mounted at boot
Comment 24 jochen 2004-10-25 16:44:51 UTC
a quick look at /sbin/rc left me with the impression devfsd is only started when devfs isn't already mounted... can this be true?

devfsd should also be started, when devfs is already mounted (imho)
Comment 25 firefox 2004-10-25 17:01:07 UTC
As in this thread, I replaced /sbin/rc with an older version and everything seems to work.

You might whan to fire diff; seems many changes regarding udev and fsdev have been made to /sbin/rc in this memorable update... ;-)
Comment 26 Shyam Mani (RETIRED) gentoo-dev 2004-10-25 18:54:28 UTC
Really memorable update ;) Had me thinking that my hard disk was kaput as well lol
Comment 27 SpanKY gentoo-dev 2004-10-25 19:29:38 UTC
1.11.4 is in cvs with the auto-mounting devfsd fixes

there's also a few other fixes, so if udev users still cant boot, open a new bug ... this one is for devfsd users
Comment 28 SpanKY gentoo-dev 2004-10-25 19:29:53 UTC
so get to it ...
Comment 29 Chris Bruner 2004-10-26 19:57:03 UTC
dumb question, but if I can't boot, how can I get it?
Comment 30 Shyam Mani (RETIRED) gentoo-dev 2004-10-26 20:53:52 UTC
Try chrooting from another Distro (like Knoppix) and roll back to 1.10.4...then get in & update.
Comment 31 David Bruha 2004-10-26 23:56:52 UTC
Looks ok to me now. The only strange thing (but perhaps it's just a glitch in my configuration) is that when init writes out "Activating (possibly) more swap", it tries to mount my standard swap partition once more and logicaly outputs error "Device busy".
Comment 32 Shyam Mani (RETIRED) gentoo-dev 2004-10-27 00:02:08 UTC
I get the same as well. Everything else is ok.
Comment 33 SpanKY gentoo-dev 2004-10-27 05:33:49 UTC
ive seen the swap warning on one of my boxes but none of the others ...
oddly, it shouldnt happen, as `swapon -a` should fail silently

as for booting, if you append 'devfs=nomount' at boot time, you should
be able to boot fine with 1.11.3
Comment 34 David Bruha 2004-10-27 05:43:30 UTC
But that would mean we would have to use udev - I am using devfs. ;)
Comment 35 SpanKY gentoo-dev 2004-10-27 06:33:27 UTC
umm, no ...

devfs=nomount means dont automount devfs at boot time

gentoo=nodevfs means dont use devfs, use udev instead
Comment 36 David Bruha 2004-10-27 07:59:51 UTC
hmm - I see
