[Rocks-Discuss] /sbin/init: error while loading shared libraries: libsepol.so.1: cannot open shared object file: Input/output error
Vadivelan Ranjith
We have configured 32-bit of rocks-4.3. We used to reboot the machine once a
month. When i rebooted the machine i got the error message
Red Hat nash version 4.2.1.10 starting
/sbin/init: error while loading shared libraries: libsepol.so.1: cannot open
shared object file: Input/output error
Kernel panic - not syncing: Attempted to kill init!
After that its not booting. Does anyone knows how to solve it.

Hi,
Input/output error usually means that the filesystem needs a fsck or that
the disk has io errors. Can you boot with a live CD and see if you can mount
the disk? Can you run a fsck? Can you run check where libsepol.so.1 is and
run: "ldd /path/to/libsepol.so.1? Does that gives you the same i/o error?
HTH,

Thanks for your reply. I booted the system with live CD and mount all the
partitions.
ubuntu@ubuntu:~$ mkdir sda
ubuntu@ubuntu:~$ mkdir sda1
ubuntu@ubuntu:~$ mkdir sda2
ubuntu@ubuntu:~$ mkdir sda3
ubuntu@ubuntu:~$ mkdir sda4
ubuntu@ubuntu:~$ sudo mount /dev/sda sda
mount: /dev/sda already mounted or sda busy
ubuntu@ubuntu:~$ sudo mount /dev/sda1 sda1
ubuntu@ubuntu:~$ sudo mount /dev/sda2 sda2
ubuntu@ubuntu:~$ sudo mount /dev/sda3 sda3
/dev/sda3 looks like swapspace - not mounted
mount: you must specify the filesystem type
ubuntu@ubuntu:~$ sudo mount /dev/sda4 sda4
ubuntu@ubuntu:~$ ls sda1
bin etc initrd media opt sbin srv tmp
boot export lib misc proc selinux sys usr
dev home lost+found mnt root share tftpboot var
Now i checked whereis libsepol.so.1. I found it was in two places.
/lib/libsepol.so.1
sda1/lib/libsepol.so.1
Then i did
ubuntu@ubuntu:~$ ldd sda1/lib/libsepol.so.1
ldd: sda1/lib/libsepol.so.1: No such file or directory
ubuntu@ubuntu:~$ sudo fsck /dev/sda1
fsck 1.40.8 (13-Mar-2008)
e2fsck 1.40.8 (13-Mar-2008)
/dev/sda1 is mounted.
WARNING!!! Running e2fsck on a mounted filesystem may cause
SEVERE filesystem damage.
Do you really want to continue (y/n)? yes
/: recovering journal
/ contains a file system with errors, check forced.
Pass 1: Checking inodes, blocks, and sizes

/: e2fsck canceled.

I cancelled it because its keep on asking for errors. I can you please
suggest me what to do.

> What does ldd /lib/libsepol.so.1 show?
Hi
It shows
ubuntu@ubuntu:~$ ldd /lib/libsepol.so.1
linux-gate.so.1 => (0xb7f27000)
libc.so.6 => /lib/tls/i686/cmov/libc.so.6 (0xb7d96000)

I not understand whether the file is available or not. When i typed cp
sda1/lib/libse [and pressed tab] it showing the following
ubuntu@ubuntu:~$ cp sda1/lib/libse
libselinux.so.1 libsepol.so.1
Then i tried to copy it
ubuntu@ubuntu:~$ cp sda1/lib/libsepol.so.1 .
cp: cannot stat `sda1/lib/libsepol.so.1': No such file or directory
Then i did ls
ubuntu@ubuntu:~$ ls sda1/lib/libse*
ls: cannot access sda1/lib/libselinux.so.1: No such file or directory
ls: cannot access sda1/lib/libsepol.so.1: No such file or directory
I not understand why its showing No such file or directory even i not
mention full name.
I have attached the screenprint of the desktop. It shows libsepol.so.1 is
available

First of all, please make a fsck with the filesystem unmounted, and then
keep trying to make fsck heal it. Only then, with a clean filesystem, you can
check if libsepol.so.1 is really there or not (i.e. ls -l , ldd, etc)
I you still get No such file or directory, check the last lines of dmesg.
Maybe you can get some more info there like disk errors.
HTH,

Install the same version of rocks in another machine (maybe a virtual
machine) and copy libsepol.so.1 to this one. And then try to boot.
Or you can install CentOS in another machine or VM and copy libsepol.so.1
from it. Or you can find in what rpm libsepol.so.1 is, extract libsepol.so.1
from it and copy it.
You will have to see if there is something else missing. Maybe something
else is missing besides libsepol.so.1 .

Sorry for trady reply. Actually i had to travel for urgent work.
I copied the library files from another system which has the same version of
rocks. But it asked one by one library. So i copied all library files from
other machine /lib . Now frontend booted. Our machine was configures pbs and
maui. Now its not working properly. When checked that directory the was no
library file in /opt/torque/lib
[root@galaxy ~]# showq
showq: error while loading shared libraries: libtorque.so.0: cannot open
shared object file: No such file or directory
[root@galaxy ~]#
[root@galaxy ~]# qmgr
-bash: /opt/torque/bin/qmgr: Permission denied
[root@galaxy ~]#
So i think i need to rebuild the rolls. I dont know how to do it. Can you
please tell me the commands how to rebuild it.

It looks like your filesystem is really damaged! Sorry, I've never rebuilt
the rolls. Wouldn't it be better to reinstall the frontend? ( backup all data
and extra programs, reinstall from scratch the same rocks version, restore
all data).
