The size of the journaled soft-updates journal should be big enough to hold two minutes of filesystem metadata-update activity. The maximum size of the soft updates journal was set in the 1990s. At the time it was assummed that disk arrays would top out at 16 drives and disk writes per drive would top out at 500 per second. Today's I/O subsystems are considerably bigger and faster than those limits. Thus this delta removes the hard upper limit and lets tunefs(8) and newfs(8) set the upper bound based on the size of the filesystem and its cylinder groups. Sponsored by: The FreeBSD Foundation |
