Hi !

I have a Red Hat 8.0 on a intel 2.4 machine with 512 MB .

I have kernel 2.4.20-30.8-legacy & 2.4.20-30.8-legacy bigmem.

I used to have all my directories /var , /tmp , /usr , /home under one
partition / .

Thanks to everybody , now I was able to re-partition my drive into extended
drives (drives < 4) and move my /var , /tmp into hda5 & ,my /usr , /home
into /hda6 .


Bu I am facing one problem.

When I boot my system logger does not see the /var/log which has been moved
to the new location  .

The system just hangs .

When I boot in single mode by passing an argument to my kernel that does
show in the dmesg in the new location .

In addtion when I run a command like 'clear ' it shows that it could not
find the library to run it .


I have mounted hda5 & hda6 in my fstab .

I did create soft link for my new var  , new tmp & new usr to the the /var ,
/tmp , /usr as ffs :-

ln -s /mnt/hda5/var  /var
ln -s /mnt/hda5/tmp /tmp

ln -s /mnt/hda6/usr /usr

I moved the old files using the ff commands:-

cd source directory

cp -ax * /mnt/usr5/var

or

cd /src/dir ; tar cf - . | (cd /dest/dir && tar xvf - )




But still it does not work .

Please find attached the dmesg & library error and fstab.

Please advice.

Thank you for your help in advance.

bj

For future reference, it is a lot easier to associate partitions with a
single top-level directory than with multiple ones, as you have chosen to
to. For example, if I assign a partition to /home, I can just mount it
there in fstab, without needing to use the symlink indirection you use:

         /dev/hda4       /home   ext2    defaults                        0
      2

At what point does it "just" hang? What is the last message on screen? And
how long do you wait ... are you sure it is a true hang and not a problem
that times out after, say, 3 minutes?

Where does your system have libncurses.so.5 (the "missing" library)? On my
systems,it is always in /lib, a hard place to lose.

This should all work fine, assuming the symlinks are created immediately
after the partitiions are mounted during the init process.

I assume the dmesg example is from the single-user boot, not the one that
"just hangs". So it doesn't tell us what is up with the hang. Next time,
please also include the output of ...

         ls -l /
         df

... and if you are reporting the results of two different boot/init
sequences (single user and multiuser) please be VERY VERY clear about which
attempt each result goes with.

Hi!

Thank you for the prompt reply .

Since I have Red Hat 8 , I had downloaded and installed (configure;make;make
install) the latest stable qt-x11-free-3.3.4 from the /home directory which
I moved .

My understanding was that wherever I downloaded the library will be still be
installed under /lib .

My /lib is where it was from the beginning . I have not moved it .

The system hangs means , the boot process shows "Starting system logger "
then just stays there because it could not find the new /var that has been
moved to /mnt/hda5/var .

The boot process also gives messages such as :-

/etc/rc.d/rc.sysinit:line 596:/var/run/utmp : no such file or directory

/etc/rc.d/sysinit:line 744: /var/log/dmesg:no such file or directory

touch:creating  'var/lock/subsys/keytable" no such file

Hence , it does not find the moved var .

It should not really hang, though it might wait 3 minutes or so to revoder 
(a typical timeout for this sort of problem, but I'm just guessing at the 
value).

In any case, you do have a problem, and it is that your /etc/fstab does not 
contain entries to mount the other partitions. The file you attached only 
has an entry for the root filesystem:

LABEL=/                 /                       ext3    defaults        1 1
none                    /dev/pts

You need a series of entries for the other partitions. I don't have such a 
system running here, so I can only give you an approximate illustration of 
what you need, not a working example. On one of my systems --

/dev/hda4       /home   ext2    defaults                        0       2

-- mounts a separate partition at /home . You need similar entries for all 
your partitions. But if I read your description correctly, you have a 
different problem too ... you tried to put 2 top-level directories into a 
single partition.

You can do that, but doing it is a bit icky. What you need to do is 
something like this (I'll use /usr and /home in the example). In fstab, put

/dev/hda5       /custom1   ext3    defaults                        0       2

Then create 2 symlinks:

         ln -s /custom1/home     /home
         ln -s /custom1/usr      /usr

Oh, you will of course have o create the mount point /custom1 as well.

I doubt it, at least for the actual example (I don't know what commends you 
think are "like" clear, so I can't generalize from your instance).

What you probably get is a message like this:

autovcr@kuryakin:~$ clear
-bash: clear: command not found

That's because the clear command is itself in /usr/bin, and your system is 
having trouble finding that directory. (clear only uses libraries that are 
normally in /lib, not ones in /usr/lib, so I doubt you are seeing clear 
unable to find libc6 or libncurses.)

>I have mounted hda5 & hda6 in my fstab .

Not the one you attached to your message.

This should serve; it is similar o my sugestion above.

This too.

For future reference, it is a lot easier to associate partitions with a 
single top-level directory than with multiple ones, as you have chosen to 
to. For example, if I assign a partition to /home, I can just mount it 
there in fstab, without needing to use the symlink indirection you use:

         /dev/hda4       /home   ext2    defaults                        0 
      2

At what point does it "just" hang? What is the last message on screen? And 
how long do you wait ... are you sure it is a true hang and not a problem 
that times out after, say, 3 minutes?

Where does your system have libncurses.so.5 (the "missing" library)? On my 
systems,it is always in /lib, a hard place to lose.

This should all work fine, assuming the symlinks are created immediately 
after the partitiions are mounted during the init process.

I assume the dmesg example is from the single-user boot, not the one that 
"just hangs". So it doesn't tell us what is up with the hang. Next time, 
please also include the output of ...

         ls -l /
         df

... and if you are reporting the results of two different boot/init 
sequences (single user and multiuser) please be VERY VERY clear about which 
attempt each result goes with.

Hi Ray !

Thank you for the prompt reply.

80 % of the solution worked .

1. I did mount hda5 & hda6 as below .

2. After I keyed in the symbolic links as below my commands could find the
lib .

3 But the sym link to /var did n't work & once I reboot , the system created
a /var by itself .The system created /var is mostly empty . If I delete that
auto created /var , and reboot , it creates the /var again .  The contents I
have listed below .

4. yes , the system stopped for 5 minutes looking to start the system logger
. After  it could not find it ,  the boot process move forward and the
normal login prompt did come( not single user but multi user login prompt )
. So you were right , the system didn't hang but just stopped for 5 minutes
trying to start the system logger .
.

I did mount hda5 & hda6 in the fstab .

Cat /etc/fstab gives the ff

LABEL=/                 /                       ext3    defaults        1 1
none                    /dev/pts                devpts  gid=5,mode=620  0 0
none                    /proc                   proc    defaults        0 0
/dev/hda5			/mnt/hda5			ext3	defaults	1 2
/dev/hda6			/mnt/hda6			ext3	defaults	1 3
none                    /dev/shm                tmpfs   defaults        0 0
/dev/hda3               swap                    swap    defaults        0 0
/dev/fd0                /mnt/floppy             auto    noauto,owner,kudzu 0
0
/dev/cdrom              /mnt/cdrom              iso9660
noauto,owner,kudzu,ro 0 0



The symbolic link also worked . After I keyed in the ff :-


cd /
ln -s /mnt/hda5/var
ln -s /mnt/hda5/tmp
ln -s /mnt/hda6/usr
ln -s /mnt/hda6/home

Once I cd /  and give the four link (ln ) commands three work .
The result running file command on the links :-

usr: symbolic link to /mnt/hda6/usr

tmp: symbolic link to /mnt/hda5/tmp


But the link to var didn't .

It gives no error message. But when I type reboot , it shows that it could
not find a file shutdown.pid under /var .
 Once I reboot , it gives quite few error messages that shows that it could
not still find /var.

It does stop around 5 minutes trying to start the system logger & after 5
minutes , it keep  boots successfully.

After I log in I notice a /var directory has been created .
This /var has been created  auto , as I didn't create it  .

The system is auto creating this directory & removing the sym link ,and so
it does not find the other needed files in /var.

Why do you think this is happening ?

In addition I would also like to have the command to mount a partition read
only such as /usr on a readonly partition.

Cheers,
bj


When I do ls -lR on the auto created /var , it gives out the ff contents :-

Re: System stops because /var/log not found after moving to new partition

[Arthur Nascimento]

Hi
Maybe you could try not to use symlinks for those folders. Keep them
as real folders and use 'mount --bind /var /mnt/hda5/var' instead
right after hda5 is mounted. Make similar commands for the other
folders and partitions.
I'm not sure it will work, but it is worth the shot.
Good luck!

I am still puzzled as to why this fix solves the library problem. I wish 
you had answered my earlier question about where the ncurses5 library is 
kept on your system.

The commands you transcribed below are incomplete and should not work. Not 
any of them.  I asked you to provide the output of "ls -l /" this time 
around, and you did not. Please do so, along with a correct transcription 
of the commands you are using to create the symlinks.

What does "ff" mean? You use it several times.

As I wrote above, these are incomplete. They should be of the form
         ln -s /mnt/hda6/usr     /usr

It is possible that your current problem arises from nothing more than your 
entering 3 of the commands correctly and the fourth (the one for /var) 
incorrectly.

Or you may have entered them too late ... after syslogd has started.

Or you may have removed the actual /usr, /tmp, and /home directories, 
allowing ln -s to recreate them as symlinks ... but forgotten to remove 
/var (this *might* be what you mean by "has been created auto" below), 
which would cause even a correct symlink command to fail.

Or some other init script may be doing something (for example, noticing 
that /var is absent and creating it) that interferes with your symlink 
approach.

Or maybe something else. It's hard to say without more detail.

Please, next time, provide the diagnostics I ask for, instead of (or in 
addition to) the ones you think are interesting.

I don't know what this sentence means, specifically the phrase "running 
file command on the links :-".

I assume we are talking about a normal multi-user boot/init here (another 
thing you may recall my asking you to be specific about in my prior 
response). In any case, it is impossible to interpret these messages when 
you tell us neither what they say or when in the boot/init process they 
appear. For example, are the messages really about /var, or might they be 
about /var/log ?

         mount  -o remount,ro /dev/whateveritis /usr

is one way. Read the man page for mount for the details.

But remember that in your setup, your /usr directory is *not* its own 
partition (which is why I used the "somethingorother" above, lacking a real 
example from your system).

OK. As I aked before, I want to see the output of ...

         ls -l /
         df
         find / -name libncurses*                (I didn't give the actual 
command before; I
                                         just asked where libncurses5 was 
located)

... and all actual error messages (not summaries or paraphrases) that you see.

Also, please provide the output of

         ls -l /mnt/hda5
         ls -l /mnt/hda6

As I wrote above, these are incomplete. They should be of the form
         ln -s /mnt/hda6/usr     /usr

It is possible that your current problem arises from nothing more than your
entering 3 of the commands correctly and the fourth (the one for /var)
incorrectly.

Or you may have entered them too late ... after syslogd has started.

Or you may have removed the actual /usr, /tmp, and /home directories,
allowing ln -s to recreate them as symlinks ... but forgotten to remove
/var (this *might* be what you mean by "has been created auto" below),
which would cause even a correct symlink command to fail.

Or some other init script may be doing something (for example, noticing
that /var is absent and creating it) that interferes with your symlink
approach.

Or maybe something else. It's hard to say without more detail.

Please, next time, provide the diagnostics I ask for, instead of (or in
addition to) the ones you think are interesting.

I don't know what this sentence means, specifically the phrase "running
file command on the links :-".

I assume we are talking about a normal multi-user boot/init here (another
thing you may recall my asking you to be specific about in my prior
response). In any case, it is impossible to interpret these messages when
you tell us neither what they say or when in the boot/init process they
appear. For example, are the messages really about /var, or might they be
about /var/log ?

         mount  -o remount,ro /dev/whateveritis /usr

is one way. Read the man page for mount for the details.

But remember that in your setup, your /usr directory is *not* its own
partition (which is why I used the "somethingorother" above, lacking a real
example from your system).

OK. As I aked before, I want to see the output of ...

         ls -l /
         df
         find / -name libncurses*                (I didn't give the actual
command before; I
                                         just asked where libncurses5 was
located)

... and all actual error messages (not summaries or paraphrases) that you
see.

Also, please provide the output of

         ls -l /mnt/hda5
         ls -l /mnt/hda6

Hi !

Thank you all for the help .

I again tried by removing the old links & recreating them in single user
mode .

cd /
 ln -s /mnt/hda5/var
 ln -s /mnt/hda5/tmp
 ln -s /mnt/hda6/usr
 ln -s /mnt/hda6/home

This time everything worked fine & my sytem is up & running.
