Expected Results:
problem does not exist with 2.6.3 or 2.6.4 win4lin kernels .. so it seems to be kernel 2.6.5-win4lin related .. 2.6.5-mm6 kernel does not seem to be effected.(on other boxes ) kernel 2.6.5-win5lin was fine until recently though so a rencent update to either baselayout (rc-scripts) or coreutils has effected the interaction with a 2.6.5-win4lin kernel only (presence or absence of CD-ISO patch does not effect the results) .. the configs on all these win4lin kernels are generally similar only a make oldconfig seperates them. I'll try a couple of things to see what else I can discover
what version of baselayout are you running on the machines that do NOT exhibit the problem?
the bizarre thing is that they are all kept up to date to the latest ~x86 level, the only thing really different is the kernel being run.. all machines are now running Gentoo base system 1.4.10 i.e. baselayout-1.8.12 although the win4lin machine has been up about 7 days without a reboot so recent changes may not be reflected .. but this was after the latest baselayout change on April 26 reboot was April 27 it also seems to have more users logged in than there really are .. not all records of logged in processes are killed when some users log-out .. there are no processes for them running but they still appear as a user. Every time they log in they leave an extra user instance behind .. I have not figured out why as yet. coreutils is now 5.2.0-r1 (april 19 installed) on all machines ..
okay I rebooted now several times with the following odd things happening on the first reboot some of the local drives apparently could not be mounted (an error comment showed up reqarding mtab and some flags .. went by too fast to remember) but according to mtab now more than just the root drive showed .. the missing ones were mounted according to /proc/mounts as rw. so I took one drive unmounted it after doing a cat /proc/mounts > /etc/mtab to trick the umount command to realize that it was there .. as root did fsck -f /dev/hda5 some directory optimaizations were made as the only fixes and remounted the drive then I logged out and rebooted again this time as the system booted this drive was flagged as having not been mounted for arround 49500 days and a fsck was forced by the boot process.. but once this had occurred everything showed up in the 'df' I executed once I'd logged in .. very odd .. all seems okay now .. but why would this sequence of events appear to fix the matter?
really odd did it again .. no drives except rootfs showed up then next reboot we got most except one .. same one(s) missing as before .. ERROR mtab message said some thing about readonly file system being mounted and use the -n flag /proc/mounts still shows all the drives .. weird .. it's almost as if we have a timing problem .. this is a relatively fast machine athlon xp 2700 MSI KT4V (via KT400) chip set.. is something in the boot sequence finishing at different times .. parallelled fsck's etc.??
okay tried a different kernel mm-sources-2.6.6_rc3-r1 after doing the bug # 48030 fixes (using nvidia-kernel-5336-r3 last one) works df gives normal expected results now for the reboot tests as there was an fsck run this boot so that changes the timings
okay all hell broke loose .. with mm-sources-2.6.6-rc3-r1 on repeated boots mtab complains that it can't create a lockfile as filesystem is read only .. then an error message appears that 'some local file systems could not be mounted' and they aren't my home directories and any mounts off of them do not appear cat /proc/mounts -- gives rootfs / rootfs rw 0 0 /dev/root / ext3 rw,noatime 0 0 none /proc proc rw,nodiratime 0 0 none /sys sysfs rw 0 0 none /dev ramfs rw 0 0 none /dev/pts devpts rw 0 0 /dev/hda12 /usr ext3 rw,noatime 0 0 /dev/hda7 /tmp ext3 rw,noatime,noexec 0 0 none /proc/bus/usb usbfs rw 0 0 df .. gives Filesystem 1K-blocks Used Available Use% Mounted on /dev/hda10 10080488 944200 8624220 10% / /dev/hda12 9273984 4566304 4236576 52% /usr rebooting with 2.6.5-win4lin gives bash-2.05b$ df Filesystem 1K-blocks Used Available Use% Mounted on /dev/hda10 10080488 944264 8624156 10% / /dev/hda12 9273984 4566304 4236576 52% /usr /dev/hda7 2087180 35308 1945848 2% /tmp /dev/hda8 10080488 5396944 4171476 57% /home bash-2.05b$ cat /proc/mounts rootfs / rootfs rw 0 0 /dev/root / ext3 rw,noatime 0 0 none /proc proc rw 0 0 none /sys sysfs rw 0 0 none /dev ramfs rw 0 0 none /dev/pts devpts rw 0 0 /dev/hda12 /usr ext3 rw,noatime 0 0 /dev/hda7 /tmp ext3 rw,noatime,noexec 0 0 /dev/hda8 /home ext3 rw,noatime 0 0 /dev/hda5 /home/extrabig ext3 rw,noatime 0 0 none /proc/bus/usb usbfs rw 0 0 any thoughts on how to remedy this? something is not staying sequenced in the boot process .. slight variations in timing appear to influence the out-come of the mounting commands I'll be glad to test any solutions as this appears to be a problem brewing for faster machines .. i'm surprised no has seen this before ..or am I wrong there.
by the way I have 3 other slower machines athlon 2500 xp, 2200 xp and a p3 750 all running mm-sources-2.6.6_rc3-r1 at the moment and this does not happen with those machines
by the way here is my /etc/fstab: It has worked without problems for at least two years .. there have been minor changes along the way as drive /dev/hdb no longer exists in this machine. # /etc/fstab: static file system information. # $Header: /home/cvsroot/gentoo-src/rc-scripts/etc/fstab,v 1.13 2003/07/17 19:55:18 azarah Exp $ # # noatime turns off atimes for increased performance (atimes normally aren't # needed; notail increases performance of ReiserFS (at the expense of storage # efficiency).

The problem appears to be in the actual mount command.
note: In spite of adding an extra mount line mtab is still not in sync with /proc/mounts all the late mounts are not visable with "df" .. if the command "mount -a" is done as root after booting then the late mounts are added to /etc/mtab but this is not happening inside "localmount"
okay this is interesting .. just commenting out the duplicated 'mount -at' line allows everything to mount normally ..??.. so I added another (second) comment line for good measure just after the original 'mount -at ...' line in /etc/init.d/localmount .. some other errors appeared how ever relating to read only filesystem and deletion of some lock files in /var/.. but root is mounted rw after all is done so ?? I'll see if it repeats it self consistently..
okay with mm-sources-2.6.6_rc3-r1 we got all kinds of ERROR s on the next boot due to lock files and rc scripts etc. not executing so alot of the scripts did not run .. but a reboot with 2.6.5-win4lin proceeded as usual with the 'some local files were not mounted error' but having them all present in /proc/mounts but at least one missing from the df listing .. Time to try something else ? any suggestions ?
Could you try whether this happens with development-sources-2.6.7? And does `mount -a` fix this (ie. do the filesystems that didn't get mounted at boot due to the mtab issues get mounted now)?
Please reopen with requested information if this issue still exists
