I have been running logstash 1.5.4, elasticsearch 1.7.2 and kibana 4.1.2 for a couple of weeks without any issues. The environment is as follows:
$ uname -a
Linux picdsr000001076 2.6.32-504.16.2.el6.x86\_64 #1 SMP Tue Mar 10 17:01:00 EDT 2015 x86\_64 x86\_64 x86\_64 GNU/Linux
JAVA\_HOME=/usr/java/jdk1.7.0\_79
CLASSPATH=/usr/java/jdk1.7.0\_79/lib
I come in this morning as get the following error.
NotImplementedError: block device detection unsupported or native support failed to load

This has been working for weeks. The env files have NOT changed and I am completely stumped. I see the issue was resolved on Solaris but this is a Linux machine.
Thanks in advance.

Have you seen [https://github.com/elastic/logstash/issues/3127](https://github.com/elastic/logstash/issues/3127) and tried the workarounds there? I've used `ln -s /lib/x86_64-linux-gnu/libcrypt.so.1 /usr/lib/x86_64-linux-gnu/libcrypt.so` myself on an Ubuntu 14.04 system.

Thank you for the quick response. Yes. I had looked at it and did run the following test and see the library:
22:28:10/nypntsrv@picdsr000001076:/local/0/deploy/elk/logstash-1.5.4]$ strace -fo jruby.failing -e trace=file vendor/jruby/bin/jruby -e 'puts File.blockdev?("/")'

Is it possible that the highlighted sequence is incorrect?
My LD\_LIBRARY\_PATH is as follows up:

Hi Magnus,
I reverted back to libcrypt-2.5.so and logstash worked. It appears that the issue occurs with libcrypt-2.12.so.
Thanks,
Shailen
