/usr/lib/dld.sl: Can't open shared library

[josinjosek]

HI,

By mistake I renamed /usr/lib/libdld.2 to /usr/lib/libdld.2.old
after that server is not allowing me to login.
I have booted the server in to single user mode, most of the commands are not working ( only cd echo are working).
I am getting below error.
# ls
/usr/lib/dld.sl: Can't open shared library: /usr/lib/libdld.2
/usr/lib/dld.sl: No such file or directory
Abort(coredump)
#

Please help me to resolve this issue. can I revert it back ?

Boot off your .prev kernel

Hi,

I booted the server with .prev kernel,its not booting giving below error.

Don't panic.

Booting with the .prev kernel won't help, because the problem is not in the kernel.

Moving the /usr/lib/libdld.2 file away broke the dynamic loader: now any binaries that require shared libraries won't run until the problem is fixed. Only statically linked programs will run. Unfortunately, all the binaries in /usr/bin will require at least the /usr/lib/libc.2 library...

The commands in /sbin are statically linked and should work even when /usr/lib/libdld.2 does not exist.

Use this command:

# /sbin/mv /usr/lib/libdld.2.old /usr/lib/libdld.2

So you already booted the server. Get back to the single user mode.

After booting to single-user mode, the root filesystem will be in read-only mode, and /usr will not be mounted. First run "mountall", then the /sbin/mv command I posted in my first reply.

The correct question is why?
If you are patching these, swinstall knows how to rename these and correctly move a new one n place.

You need to use atomic "ln -f":
ln -f /usr/lib/libdld.2 /usr/lib/libdld.2.old
ln -f /usr/lib/libdld.2.new /usr/lib/libdld.2

Note: Since dld and libdld have to be in sync, you really need to modify both at the same time and that may require /sbin/ln -f.

Hi Dennis,

Thanks a lot for providing different approach to solve this issue.

issue is already resolved by
# /sbin/mv /usr/lib/libdld.2.old /usr/lib/libdld.2
server is working fine now.
