Commands and strategies to manage filesystems on Linux servers.

A basic question when getting into HPC is how to get data into and out of the cluster from local Linux and Windows machines.

One of the most underutilized capabilities in Linux and HPC is compressing unused data files.

SSHFS is often overlooked as an HPC shared filesystem solution.

HPC systems require shared filesystems to function effectively. Two really good choices for both small and large systems are NFS and SSHFS.

If you are an intensive, or even a typical, computer user, you store an amazing amount of data on your personal systems, servers, and HPC systems that you rarely touch. SquashFS is an underestimated filesystem that can address that needed, but little used, data.

NFS is probably the most widely used shared filesystem. You can turn many knobs to boost performance, ease management, and improve security.
