I backed up my database and I'm now upgrading to v2.1.16.
I've tested my backup and restore routine on a local Vagrant virtual server and everything went fine.
I'm now trying to run the same procedure on my Amazon AWS server, and the process fails due to a OLowDiskSpaceException.
Here is the message I'm getting:

The weird thing is I have plenty of free space available. Running 'df -h' returns:

Why is OrientDB convinced I have less than 100MB of free space, when in fact I have over 5GB?

I'm able to start my orientDb (2.2.6) instance using a plocal connection and able to add vertices to the DB but I can't access the studio. When I go to http://localhost:2480, the page is blank. Isn't studio ready and available 'out of the box'?

I get these warnings whenever I try to access localhost:2480 from Chrome:
2016-09-28 16:56:01:756 WARNI path variable points to 'src/site' but it doesn't exists [OServerCommandGetStaticContent]
2016-09-28 16:56:01:756 WARNI path variable points to 'src/site' but it isn't a directory [OServerCommandGetStaticContent]
What am I missing?
I'm running OrientDB 2.2.6 on Windows 7 (64 bit) and I keep getting the following warning when I run a TestNG test in Java 8.
2016-10-05 10:46:10:888 WARNI {db=orientSystemDb} Maximum amount of pinned pages is
reached, given page OReadCacheEntry{fileId=7136553380276606136, pageIndex=0,
dataPointer=OCachePointer{referrersCount=1, usagesCount=0}, dirty=false, usagesCount=1}
will not be marked as pinned which may lead to performance degradation. You may consider
to increase percent of pined pages by changing of property storage.diskCache.pinnedPages
[O2QCache]
I'd prefer not to increase the percent of pinnedPages right now since memory usage will probably be limited. What I would like to do is clear the pages that have been pinned when the database has started and see if that resolves the issue.
Here is my config file:

Here is the code for creating edges:

{
int numConnections = 0;
for(Vertex v : oGraph.getVertices())
{
if(v.equals(oVertex))
{
// skip it
continue;
}
oVertex.addEdge(String.format("connection%s", numConnections), v);
numConnections++;
}
return numConnections;
}
I'm able to create the edges but I keep getting the above warnings. How can I clear the pinned pages before running my tests?
Pinned pages is special area of disk cache which unloaded from RAM only when OrientDB storage is closed. So you may try using closeStorage method. See javadoc.
My goal is to have two nodes. Node A should write some vertices and node B should be able to read those vertices.
So far my hazelcast discovery works just fine. OrientDB will also hot deploy any found database from nodeA to nodeB. Unfortunately any write on Node A will not be replicated to nodeB.
My setup:
orientdb-server-config.xml:
Simplified version (copied from orientdb-community tar.gz)
%NODENAME% will be replaced with nodeA or nodeB.

Start OServer:
OServer server = OServerMain.create();
server.startup(getOrientServerConfig());
server.activate();
Wait until both nodes have been started.
Each node connects to the graph database.
OrientGraphFactory factory = new OrientGraphFactory("plocal:" + new File("databases/db_testdb").getAbsolutePath());
NodeA will add new vertices using getNoTx.
NodeB will just read the graph and count the found vertices using getNoTx.
I created a very basic maven project which contains two tests that will start nodeA and nodeB.
It is mandatory to set the ORIENTDB_HOME property for each node. The property must be set that way so that the $ORIENTDB_HOME/databases folder can be located. I have updated the maven project.
Each node can set the property for example this way:
String orientdbHome = new File("").getAbsolutePath();
System.setProperty("ORIENTDB_HOME", orientdbHome);
I am trying to get Orient DB running embedded and distributed. Right now I am facing a StackOverflowError whenever I open my local DB if the hazelcast plugin is active. When I turn the hazelcast plugin off, everything is fine.
OrientDB is getting stuck in this loop:

at com.orientechnologies.orient.server.distributed.ODistributedAbstractPlugin.onOpen(ODistributedAbstractPlugin.java:141)
The ODatabaseRaw.open has a list of listeners, when Hazelcast is active the plugin is registered as a listener, and will be called everytime the method runs.
Anyone has any ideas?
Edit:
I kind of got it to work, I had taken the distributed configuration from github. When I remove the following line it works:
<parameter name="conflict.resolver.impl" value="com.orientechnologies.orient.server.distributed.conflict.ODefaultReplicationConflictResolver" />
I am not really sure if this is such a good solution though, so feel free to point out better solutions =)
My complete configuration looks like this:

Does not seem to very stable yet when running distributed and embedded. A shame really, liked it so far...
my Nlog Config is:
<commandText>
insert into NLog_Error ([time_stamp],[level],[host],[type],[source],[logger],[message],[stacktrace],[allxml]) values(#time_stamp,#level,#host,#type,#source,#logger,#message,#stacktrace,#allxml);
</commandText>
<parameter name="#time_stamp" layout="${utc_date}" />
<parameter name="#level" layout="${level}" />
<parameter name="#host" layout="${machinename}" />
<parameter name="#type" layout="${exception:format=type}" />
<parameter name="#source" layout="${callsite:className=true:fileName=false:includeSourcePath=false:methodName=false}" />
<parameter name="#logger" layout="${logger}" />
<parameter name="#message" layout="${message}" />
<parameter name="#stacktrace" layout="${exception:stacktrace}" />
<parameter name="#allxml" layout="${web_variables}" />
but my log output in mssql is empty. do not insert any data
what?
Try to enable the nlog internal error message. Maybe you can find some clues there:
