Description

When trying to copy file on CEPH filesystem, FileUtils.copyFile fails with exception. I don't see any workaround except of replacing that call and rebuilding the project.

Test Case:

Here's a simple class to reproduce the issue:

 

 

import org.apache.commons.io.FileUtils;
import java.io.File;
import java.io.IOException;
import java.io.PrintWriter;
import java.nio.file.Files;

public class Test3 {
    public static void main(String[] args) throws IOException {
        PrintWriter writer = new PrintWriter("file.txt", "UTF-8");
        writer.println("test input " + Math.random());
        writer.close();
        FileUtils.copyFile(new File("file.txt"), new File("file-copy.txt"));
    }
}

below is the stacktrace:

Exception in thread "main" java.io.IOException: No such device at sun.nio.ch.FileChannelImpl.map0(Native Method) at sun.nio.ch.FileChannelImpl.map(FileChannelImpl.java:926) at sun.nio.ch.FileChannelImpl.transferFromFileChannel(FileChannelImpl.java:634) at sun.nio.ch.FileChannelImpl.transferFrom(FileChannelImpl.java:708) at org.apache.commons.io.FileUtils.doCopyFile(FileUtils.java:1131) at org.apache.commons.io.FileUtils.copyFile(FileUtils.java:1076) at org.apache.commons.io.FileUtils.copyFile(FileUtils.java:1028) at ztst.Test3.main(Test3.java:17)

Here's our server's file system configuration:

1. a squashfs (read only) image stored on a ceph's rbd
2. a directory on cephfs (read/write)

1 is the lower layer and 2 is the upper layer of an unionfs mount with the following options:

cow
max_files=32768
allow_other
use_ino
direct_io
statfs_omit_ro
nonempty
