Great cheat sheet. Thanks.

Perhaps someone more experienced than I can help me troubleshoot this though... Crashplan v3.6.4 was working fine on my ReadyNAS Ultra4+ until recently... I'm not sure if something changed such that we require the latest versions of the clients to work with the CrashPlan service. So, updating to 4.3.0 seemed to work fine after uninstalling 3.6.4, but upon trying to launch 4.3.0 on my ReadyNAS the following is in the engine_error.log:

/usr/local/crashplan/jre/bin/java: error while loading shared libraries: libdl.so.2: cannot open shared object file: No such file or directory

Any guidance on what to do about that?

I verified that "jre-7u45-linux-x64.tgz" properly downloaded and unpacked in the java path set on "JAVACOMMON=/usr/local/crashplan/jre/bin/java"

I am at a loss right now. Thanks.

I managed to get Crashplan 4.4.1 up and running on my NAS (ReadyNAS Ultra 4). All I had to do was to swap out the x64 JRE package with the 586 version instead, after completing the usual install. The install.defaults file contains the URL for the correct file, so just download that one:

(I'm doing all of this in ~/crashplan-install/)

wget http://download.code42.com/installs/proserver/jre/jre-7-linux-i586.tgz

then unpack and swap the x64 version with the 586 version:

tar -zxf jre-7-linux-i586.tgz

mv /usr/local/crashplan/jre/ /usr/local/crashplan/jre-x64

mv ~/crashplan-install/jre /usr/local/crashplan/jre

then start the Crashplan service. Voila!

Obviously, the installer picks the wrong architecture for the NAS. Hope this helps.

Yeah, that appears to be the issue... the Crashplan installer script does not pick the correct architecture for the ReadyNAS Ultra4+ it seems. I guess we should report that to them, but that said, we are shoe-horning the vanilla "Linux" install onto a NAS, which they show as unsupported.

Thanks all. Hope this helps others in the same boat.

That wasn't really my problem. The upgrade failed right away because the java version was 1.6. Crashplan did not attempt to update java.

Wed Sep 23 20:39:17 EDT 2015 : JAVACOMMON is set: /usr/bin/java
Wed Sep 23 20:39:17 EDT 2015 : Current Java Version: 1.6
Wed Sep 23 20:39:17 EDT 2015 : This client requires one of these JREs: 1.7 1.8. Exiting upgrade

Installing jre 1.8 (and changing JAVACOMMON to point to it) solved the problem.

  How did you go about installing JRE 1.8 directly on your ReadyNAS? I tried to find an apt-get repository that worked, but that failed. I only have a working version of JRE 1.6 (when Java was still Sun) that was installed directly via apt-get (Debian archive).
  
  The EJRE installer add-on for the ReadyNAS failed to even install for me.

    The add-on installer worked for me with no issues
