mount_nilfs
mount a NILFS file system

mount_nilfs [-c checkpoint] [-o options] [-t gmtoff] special node

NILFS is a log-structured file system designed to support fast writing, fast recovery times, live snapshots, concurrent read-only snapshot mounts, and live file system resizing. Its inodes are managed using B-trees.

The mount_nilfs command attaches the NILFS file system residing on the specified special device node on the location indicated with node.

NILFS is a file system developped by NTT and released in 2005 for Linux. Version 2 is available since 2009. This cleanroom implementation was written by Reinoud Zandijk for NetBSD in 2009, and has first been released as part of NetBSD 6.

This implementation of NILFS was written by Reinoud Zandijk.

This implementation currently only supports read-only operation. See mount_lfs(8) for an older log-structured file system with write support. Also see wapbl(4) and mount(8) for fast journal-based recovery using FFS.
