Hi, A while ago I tried using Lustre as storage target for elasticsearch with no luck, at the time I didn't really have time to look at it. Today I looked at it again.
Apparently it tries to run a native locking function that isn't implemented in java: Caused by: java.io.IOException: Function not implemented at sun.nio.ch.FileDispatcherImpl.lock0(Native Method) ~[?:?] at sun.nio.ch.FileDispatcherImpl.lock(FileDispatcherImpl.java:90) ~[?:?] at sun.nio.ch.FileChannelImpl.tryLock(FileChannelImpl.java:1115) ~[?:?] at java.nio.channels.FileChannel.tryLock(FileChannel.java:1155) ~[?:1.8.0_141] at org.apache.lucene.store.NativeFSLockFactory.obtainFSLock(NativeFSLockFactory.java:114) at org.apache.lucene.store.FSLockFactory.obtainLock(FSLockFactory.java:41) at org.apache.lucene.store.BaseDirectory.obtainLock(BaseDirectory.java:45) So I was wondering would this issue be solved by Lustre bindings for Java or is this a way of locking that isn't supported by Lustre? Is anyone else using elastic on Lustre? How did you do it? Thanks, Eli
