It is believed that many inexperienced people have no idea about how to operate CephFS in JAVA. Therefore, this paper summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

Add MAVEN dependency com.ceph libcephfs 0.80.5 example code import com.ceph.fs.CephMount;import java.io.IOException;public class CephFSTest {public static void main (String [] args) {/ / admin is the admin user CephMount mount = new CephMount ("admin") of ceph; / / 10.112.101.141it10.112.101.142 10.112.101.143 is the mon node of the ceph cluster, and how many mount.conf_set are written ("mon_host", "10.112.101.141 / 10.112.101.142 / 10.112.101.143"); System.out.println (mount.conf_get ("mon_host")) / / the following key comes from the key mount.conf_set ("key", "AQAfN2dZzp19OhAAKlQz2rKKoBATIuGdBkXD0A==") in / etc/ceph/ceph.client.admin.keyring of the ceph environment; / / you must mount to the root directory mount.mount ("/") before creating a directory. / / creating a subdirectory mysqlDB,0777 under the root directory is to control the permissions of the directory. This can be changed to something else, but it is best to let the directory have read and write permissions try {mount.mkdirs ("/ mongoDB/", 0777);} catch (IOException e) {e.printStackTrace ();} / / break mount mount.unmount () after creation System.out.println ("success");}} after reading the above, have you mastered the method of how to operate CephFS in JAVA?
