Boot log doesn't work on my machine.
If probmel not clear for you, I try exlain.
The boot script mount "/" read-only,
after that it execute fsck.jfs
which ask:
jfsutils-1.1.10/fsck/xchkdsk.c:
printf("\n%s is mounted.\n\nWARNING!!!\n"
"Running fsck on a mounted file system\n"
"may cause SEVERE file system damage."
"\n\n", Vol_Label);
ask_continue();
Afetr that I so "no",
it remount file system read-write and continue.
From jfs_fsck(8):
WARNING
jfs_fsck should only be used to check an unmounted file system or a
file system that is mounted READ ONLY. Using jfs_fsck to check a file
system mounted other than READ ONLY could seriously damage the file
system!
somehow your system loads up with / being read write ... it shouldnt be the boot scripts attempt to remount / read only, but fail as you can see in your log that you posted: / - mount readonly so you need to find out why your / is loaded up as read write One more thing:
---------------------------------
case MSG_JFS_VOLUME_IS_MOUNTED:
if (agg_recptr->parm_options[UFS_CHKDSK_LEVEL0]) {
/* read only */
fsck_send_msg(fsck_FSMNTD);
fsck_send_msg(fsck_MNTFSYS2);
} else {
/* is mounted */
printf("\n%s is mounted.\n\nWARNING!!!\n"
"Running fsck on a mounted file system\n"
"may cause SEVERE file system damage."
"\n\n", Vol_Label);
ask_continue();
}
break;
---------------------------------
How can you see in case if "jfs" mounted,
it check mounted it read-only or not,
if not it ask this "stupid" question, and I can not get "ssh "access".
I have "/usr/portage" partition with "jfs"
# mount /usr/portage/ -o ro
# mount -l | grep /usr/portage
/dev/sda7 on /usr/portage type jfs (ro,noatime) [portage]
# fsck.jfs /dev/sda7
fsck.jfs version 1.1.10, 19-Oct-2005
processing started: 4/17/2006 11.13.37
Using default parameter: -p
The current device is: /dev/sda7
Block size in bytes: 4096
Filesystem size in blocks: 1279167
**Phase 0 - Replay Journal Log
Filesystem is clean.
So it didn't ask nothing if partition mount read-only,
but during boot, for some reason this didn't work.
>so you need to find out why your / is loaded up as read write here is more detailed log: >> Acitvating udev >> Determining root device... >>Mounting root... >>Booting (initramfs)... INIT: version 2.86 booting ... * Mounting /dev/udev... * Populating /dev with saved device nodes ... udevd-event[]: find_free_number: %e is deprecated ... * Remounting root file system read-only mount / is busy * Checking root filesystem I should say, that the problem as I described above,
happend not always, often but not always.
I suppose that somebody doesn't "unmount" before "/" is mounted.
I add in /etc/init.d/checkroot:
start() {
sleep 5 <---
local retval=0
and now seems all ok.
I have
/etc/conf.d/rc
RC_PARALLEL_STARTUP="no"
and before "checkroot"
happend only
mounting /proc
mount /sys
and starting udev
so I suppose this is udev problem
