XtreemFS Service And Modules

XtreemFS is based on three services and kernel module called fuse:

Dir – Directory Service : It is used by the MRC, OSD and client to find other servers, resolve UUID mapping and volume names.

MRC – Metadata and Repica Catalog : It stores the volumes with their directory tree and all metadata for files in the volumes.

OSD – Object Storage Device : It is not a special device it is regular server, these servers store the file content and implement the replication.

FUSE – File-system in Userspace : It is a kernel module that simplifies the development of new file systems.

Mounting XtreemFS

To mounting XtreemFS fist start the directory service typing below command:

# /etc/init.d/xtreemfs-dir start

Start Metadata server:

# /etc/init.d/xtreemfs-mrc start

Start the OSD:

# /etc/init.d/xtreemfs-osd start

Load the Fuse kernel module if not loaded.

# modprobe fuse

Create a new volume with it default setting:

# mkfs.xtreemfs localhost/Volume

Create a mount point:

# mkdir ~/xtreemfs

Mount XtreemFS on your system:

# mount.xtreemfs localhost/Volume ~/xtreemfs

That’s it now you can use your volume.

Unmounting XtreemFS

Type the below command to unmount the XtreemFS:
