Filelight is the answer to you. Filelight creates an interactive map of concentric, segmented rings that help visualize disk usage on your computer. Like a pie-chart, but the segments nest, allowing you to easily see which files are taking up all your space.http://linuxcrunch.com/content/filelight-where-my-disk-space-has-gonelystrata2010-01-03T18:53:31+01:00disk file filesystem sysadmin <span itemprop="description">One task that every one should do it is deleting useless files.

This saved me from having to get the kernel source, and patch it for Lustre. I've done that before with some success, but I'm happy to be able to avoid doing it again. The following applies to setting up Rocks so that Lustre is installed and ready on compute nodes. I also put Lustre on the frontend node, but that was done manually, simply by installing the rpms, and configuring grub.http://www.aoc.nrao.edu/~mpokorny/rocks_lustre.htmllystrata2009-10-18T19:44:41+02:00cluster filesystem luster rocks <span itemprop="description">Thankfully, Rocks v4.3 kernel roll and Lustre v1.6.1 appear to be based on the same kernel version.

The result of a research project funded by the EU, XtreemFS is designed for distributed data management in grids, but is also meant to simplify accessing local files over the internet. It's easy to set up, supports RAID-0 (striping) over different machines and file replication over the network, encrypts data, and provides security mechanisms to ensure only authorised users can access shared files. Unlike sharing via NFS or SMB/CIFS, the file system can extend over several servers, provides security mechanisms, and is optimised for use over slow and not totally reliable internet connections. The file system runs in user space (via FUSE under Linux, via Dokan under Windows), so it can do without drivers or a kernel module. Linux and Windows are supported on the client side, and a Mac OS X client is under construction. The server runs under Linux and Solaris, and the software is licensed under the GPLv2.http://www.h-online.com/open/Distributed-file-system-for-the-internet--/news/114009lystrata2009-08-16T05:32:32+02:00dfs filesystem gfs storage <span itemprop="description">The developers have released version 1.0 of the XtreemFS distributed file system.
