1.5.2. Introduction to CVMFS

C.f. CVMFS.

Properties of CVMFS:

  • POSIX read-only file system

  • user space (FUSE module)

  • shares a universal namespace under /cvmfs/...

  • world readable

  • content managers: only special users who registered as content managers can write to this space (See Register as a new content manager (CVMFS) and Publishing to CVMFS.)

  • synchronization lag: it takes some time for it to be synchronized from the publishing node. Empirically, it takes around 2.5-3 hours for contents to be sync’d on Blackett.

  • world-readable: Anyone can see the contents so no secrets should be placed here.
