AFS and filesystems

Printer-friendly versionPrinter-friendly version

In Informatics we use AFS for most file storage. It's authenticated (via kerberos) with load balancing, local caching, and global access. (Historical note: this document describes why we chose AFS.)

If you're in a hurry read AFS top tips.

If not, the OpenAFS Documentation pages give a general introduction. See also the slides from the AFS Basics talk.

For help with access permissions (and remember that this is a global filesystem), take a look at Setting ACLs. For other command information, see the local copy of the Official AFS Reference Manual, and also the OpenAFS User Guide.

Each area of AFS filespace has a quota, described on the disk quotas page.

AFS clients are not just available for the DICE Linux machines, they're also available for other operating systems and platforms:

AFS can also be accessed on the web using ifile, and you can serve web pages from AFS using sweb.

Other filesystems

Although AFS is used for DICE home directories and the majority of data space, desktop machines also have local disk. The local disk filesystems are ext4.

If you need to get access to files on a remote machine, but the filespace on that machine isn't normally visible from your machine, you can often access it using sshfs.
