SC 3.5.0c Linux install - bad libs?

[JIM_SURLOW]

I recently received a copy of 3.5.0c.  Untarred it onto a new CentOS 5.7 and placed it into /usr/local as per the 3.4 documentation (don't know if there is a 3.5 docs anywhere).

Then went to run it and received ...

[root@81377-sanperf scServer3.5.0c]# ./snapcreator --profile setup

Panic: '/usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi/CORE/libperl.so' is not an ActivePerl library

A quick ldd …

[root@81377-sanperf scServer3.5.0c]# ldd snapcreator

linux-vdso.so.1 =>  (0x00007fff413fd000)

libnsl.so.1 => /lib64/libnsl.so.1 (0x0000003985200000)

libdl.so.2 => /lib64/libdl.so.2 (0x0000003982e00000)

libm.so.6 => /lib64/libm.so.6 (0x0000003983600000)

libcrypt.so.1 => /lib64/libcrypt.so.1 (0x0000003984a00000)

libutil.so.1 => /lib64/libutil.so.1 (0x0000003985a00000)

libpthread.so.0 => /lib64/libpthread.so.0 (0x0000003983e00000)

libc.so.6 => /lib64/libc.so.6 (0x0000003982a00000)

/lib64/ld-linux-x86-64.so.2 (0x0000003982600000)

Not sure where to go from here

Thanks,

Jim

Can you try the 32bit version of the linux binary for SC? Also can you run the following command: strace ./snapcreator --version. This will produce a stack trace. Also a plain ./snapcreator --version would be good.

I have CentOS 5.5 and it works fine, we rarely here of issues like this but it is some kind of incompatibility

You can also try installing ActiveState perl, www.activestate.com and setting that perl before other perl in search path

Let me know

Regards,

Keith

Ok I sent this to some of the devs, I am not sure we have ever seen this. It is very odd that Snap Creator would be loading libperl.so from perl5 directory, something isn't right.

I have two more things you can try:

1. Take perl5 out of the path so it doesnt find the libperl.so, this may at least point us to source of problem. If you get a new error, then grab an strace.

2. Try the 32bit version not the 64bit version. There could be some missing libs required for 64bit on your OS.

Let me know

Regards,

Keith

Hi Jim,

I somehow missed this and now it is starting to make sense

Snap Creator bundles its own libperl.so, like I said we dont require external software.

What I believe is happening is Snap Creator is not finding the libperl.so it comes with and so it moves on to libperl.so which is found under perl5

open("/usr/local/scServer3.5.0c/libperl.so", O_RDONLY) = -1 ENOENT (No such file or directory)

This open and others fail and that is the problem

The reason why this could happen is tmp is full or there is no tmp directory. SC requires a tmp directory.

Verify if tmp has space if it doesnt free up some space, make sure temp is writable as well.

Re-run ./snapcreator --version

Let me know if this helps

Regards,

Keith

[JIM_SURLOW]

Keith,

Looks like I have enough space ....

[root@81377-sanperf ~]# df -h /tmp

Filesystem            Size  Used Avail Use% Mounted on

/dev/sda2             2.0G   44M  1.8G   3% /tmp

[root@81377-sanperf ~]# ls -ald /tmp

[root@81377-sanperf ~]# sum Snap_Creator_Community_Release_3.5.0-Linux64.tar

42018 68710

[ktenzer]

Ok that rules out tmp being issue. I just did cksum on tarball and on binary this is what i see and it is working:

1081640792 70359040 Snap_Creator_Community_Release_3.5.0-Linux64.tar

1665762593 6344160 snapcreator

Can you do a cksum on snapcreator binary and verify?

Regards,

Keith

[JIM_SURLOW]

[root@81377-sanperf scServer3.5.0c]# cksum snapcreator

1665762593 6344160 snapcreator

1081640792 70359040 Snap_Creator_Community_Release_3.5.0-Linux64.tar

This is interesting... still looking for ActivePerl...

[root@81377-sanperf scServer3.5.0c]# bash

[root@81377-sanperf scServer3.5.0c]# export PATH=/usr/local/bin

[root@81377-sanperf scServer3.5.0c]# echo $PATH

/usr/local/bin

[root@81377-sanperf scServer3.5.0c]# ./snapcreator --version

Error: Can't locate libperl.so

Make sure the ActivePerl bin directory is in your PATH

PATH=/usr/local/bin

[ktenzer]

Ok then let's try the 32bit version and see if that work

Regards,

Keith

[JIM_SURLOW]

Keith,

In poking around, I found some interesting stuff in /tmp.  Is pdk-root from SC?  I am guessing so....

I started the 64-bit test in the morn and 32-bit test in the eve.

[root@81377-sanperf ~]# find /tmp -name libperl.so -ls -exec file {} \;

131075 1584 -rw-r--r--   1 root     root      1614981 Jan 12 09:07 /tmp/pdk-root/990f144bacb50cb035b7702a643c4708/libperl.so

/tmp/pdk-root/990f144bacb50cb035b7702a643c4708/libperl.so: ELF 64-bit LSB shared object, AMD x86-64, version 1 (SYSV), not stripped

131077 1412 -rw-r--r--   1 root     root      1440083 Jan 12 20:25 /tmp/pdk-root/8a5466952c718e5e0b84210ae7ff7605/libperl.so

The 32-bit version gave me...

[root@81377-sanperf scServer3.5.0c]# ./snapcreator --version

Error: Can't locate libperl.so

Make sure the ActivePerl bin directory is in your PATH

PATH=/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin

[ktenzer]

That is normal, SC unpacks libs and leaves them under /tmp.

For some reason SC simply can't load the libs it comes with. This probably indicates some incompatibility with the libs and OS. I think we are going to have to reproduce this issue to understand it.

Is there anyway you can use some other OS? SuSE or RedHat, maybe even a different CentOS system or even windows?

Regards,

Keith

[JIM_SURLOW]

Keith,

From what you said earlier, you package your own libperl.so, and from my earlier strace and the latest with the 32-bit, I see that it is being found.

[root@81377-sanperf scServer3.5.0c]# strace ./snapcreator --version 2>&1 | egrep 'tmp.*libperl'

open("/tmp/pdk-root/8a5466952c718e5e0b84210ae7ff7605/libperl.so", O_RDONLY|O_LARGEFILE) = 3

open("/tmp/pdk-root/8a5466952c718e5e0b84210ae7ff7605/libperl.so", O_RDONLY) = 3

[root@81377-sanperf scServer3.5.0c]# cd ../scServer3.5.0c-64/

[root@81377-sanperf scServer3.5.0c-64]# strace ./snapcreator --version 2>&1 | egrep 'tmp.*libperl'

open("/tmp/pdk-root/990f144bacb50cb035b7702a643c4708/libperl.so", O_RDONLY) = 3

open("/tmp/pdk-root/990f144bacb50cb035b7702a643c4708/libperl.so", O_RDONLY) = 3

For the 32-bit version, I'm not sure why it is looking in /root/bin/perl

read(3, "\177ELF\2\1\1\0\0\0\0\0\0\0\0\0\3\0>\0\1\0\0\0\340\34c\2059\0\0\0"..., 512) = 512

close(3)                                = 0

stat64("/root/bin/perl", 0xfff0b440)    = -1 ENOENT (No such file or directory)

write(2, "Error: Can't locate libperl.so\nM"..., 199Error: Can't locate libperl.so

[justints]

As Keith said for some reason libperl.so present in snapcreator is not getting loaded. Could you do a ldd on /tmp/pdk-root/8a5466952c718e5e0b84210ae7ff7605/libperl.so. Some dependencies mite be missing. I just ran snapcreator on CentOs 6.2. It works like a charm.

Regards,

Justin Skariah.

[ktenzer]

Yep I think Justin is right, something is missing. Just tested CentOS 5 and it worked as well.

Regards,

Keith

[JIM_SURLOW]

Justin, Keith,

Keith - could one of you do a "yum grouplist" for me?  Maybe I don't have a dependent development library installed.

Justin -

Can't ldd the .so as it is not a dynamic executable.

[root@81377-sanperf 990f144bacb50cb035b7702a643c4708]# chmod 755 libperl.so ; ldd libperl.so ; chmod 644 libperl.so

        not a dynamic executable

[ktenzer]

Hi Jim,

I am running CentOS 5.3, here is the yum grouplist:

I am guessing Development tool or Development libraries are missing. There is simply some libraries that arent available on your machine.

I've started add a couple from your list that I did not have.  So far, no joy.  My RedHat 5.3 is more restrictive that your list and the 64-bit works without issue.  I wonder what is in CentOS 5.7 that is giving me grief.

[JIM_SURLOW]

"runs without issue" = doesn't panic when no params are given.

[ktenzer]

This problem is very strage we have never seen this. SC runs on 1000s of systems and a lot are linux and we have never seen this. We also cant reproduce it. We have tried CentOS 5.3 (works) and CentOS 6.2 (works). I can install 5.7 but wont get to it until the weekend, maybe 5.7 has some bugs and we can reproduce it, or something is missing (more likely the case).

Why cant you install SC on some other system? I dont understand why it has to be 5.7 and this particular system, this is just for testing so anything will do. we just need a server that can talk to vCD and vCenter, that is it.

Regards,

Keith

[JIM_SURLOW · Accepted solution]

I found out that the template that I was using for CentOS had a noexec /tmp partition.  snapcreator runs now.

[ktenzer]

Hi Jim,

This is great news! I was about to test CentOS 5.7 to reproduce issue but I

guess I will save myself that effort

Please let us know if you have any other questions and if you get vCD

backup/restore working.

Regards,

Keith
