| 16007 | What is the purpose of fsflush? | 12 May 1998 |
| Description | Top |
From "The magic garden explained": fsflush is a system process started at system boot. It is awoken each second in clock() to flush cached data to its storage device. This includes the system's buffer cache, in-core inode cache and mapped-in memory pages. To bring some form of data integrity to the UNIX file subsystem implementation, the designers chose to flush the in-core inode tables of each file system each second from fsflush. This mechanism is known as "file system hardening".
