CRFS is an acronym which stands for ‘Coherent Remote File System’. CRFS is a
network protocol that lets clients share access to a file system which is
hosted on a server. Its main features include:

• general-purpose “posix” file system semantics
• cache coherency
• aggressive metadata performance
• efficient and flexible snapshots
• robust data integrity protection

The implementation hosted here includes a client module for the Linux kernel
and a UNIX user space server daemon. ‘crfsd’, the UNIX daemon which runs in
userspace, provides these features by storing data in a BTRFS file system on
disk.
