  MINIX file system - Wikipedia, the free encyclopedia   (Site not responding. Last check: 2007-10-21)
The Minix file system is the native file system of the Minix operating system.
Minix was written from scratch by Andrew S. Tanenbaum in the 1980s, as a Unix-like operating system whose source code could be used freely in education.
The Minix file system was designed for use with Minix; it copies the basic structure of the Unix File System but avoids any complex features in the interest of keeping the source code clean, clear and simple, to meet the overall goal of Minix to be a useful teaching aid.

 Minix
Minix was a commercial stripped-down version of UNIX that ran on IBM PC and IBM PC/AT[?] computers in the late 1980s and early 1990s.
Minix was written by Andrew Tanenbaum from Vrije Universiteit, Amsterdam, The Netherlands as an appendix or example in the book "Operating Systems: Design and Implementation", ISBN 0-13-637331-3.
The whole 12000 lines of source code of the kernel, memory manager, and file system is printed in the book; it is mostly written in C.

 Ext2 - Biocrawler   (Site not responding. Last check: 2007-10-21)
The ext2 or second extended file system was the standard filesystem used on the Linux operating system for a number of years and remains in wide use.
Minix file system was pretty free of bugs, but had some limitations like being able to handle only 64 megabytes of data, due to its 16-bit address space and accepted file name with no more than 14 characters.
After its integration to the kernel, the extended file system (ext) was released as the first file system designed for Linux in April 1992 and it was included in Linux version 0.96c.

Overview The job of the file system is to allocate and deallocate file space, keep track of used and free disk blocks, provide file naming scheme, and provide protection.
MINIX fs is really a (network) file server since it works by message passing.
Directories, Paths For open, a file name or path string must be translated into an i- node to be loaded into in-memory i-node table.

 Unix for Advanced Usersu - The Unix Filesystem - Unix filesystem commands
Rescue disk systems usually consist of one or two floppy disks that contain a kernel and a tiny root file system that contains the bare minimum that is needed to get a system up and repaired.
These file systems are attached to the root file system at mount points, which are empty directories until file systems are attached at them.
The partition that is to be mounted as the root file system is usually compiled into the kernel, or in some operating systems it can be passed to the kernel as an option at boot time.

The ext2 or second extended file system is a file system for the Linux kernel.
The Minix file system was mostly free of bugs, but used 16-bit offsets internally and thus only had a maximum size limit of 64 megabytes.
The extended file system (ext), was released in April 1992 as the first file system using the VFS API and was included in Linux version 0.96c.

Directory files are used by the O/S to maintain the hierarchical file system.
For example, Minix is a simple version of Unix, and Linux has the option to use a Minix file system.
Since a file uses at least one block, small block sizes are desirable, but since they have to be read from and written to disk, large sizes are desirable.

Now assume there is a Minix file system on the disk.
The file system organizes the disk into 6 sections (of blocks).
But, when we create a file system on a disk, we don't know how many files there will be, so we have to make an educated guess and leave a lot of room for a bunch of inodes.

 COP 4600 - Solaris-Minix User Guide   (Site not responding. Last check: 2007-10-21)
There is a write system call (write to a file) and a write command (send a message to another user on their screen).
The Minix operating system consists of five binary files: src/kernel/kernel, the operating system kernel, src/mm/mm, the memory manager, src/fs/fs, the file system, src/inet/inet, the network manager, and src/tools/init, the ancestor of all user processes.
This command finds all of your source files in src and include that differ from the original Minix distribution, and copies them into a new directory with the name Backup/date, where date is the date and time that the backup was made.

A file system is said to be contiguous if logically contiguous blocks of all files of the file system are also physically contiguous.
Note that most file systems are not contiguous; blocks are scatter-stored and mapped by information in the inode.
Note that the size of a contiguous file must be stated at the time of its creation, and the file cannot grow over it's lifetime (one must create a bigger file, copy the old one into the first part of the new, and delete the old file).

 CS111 Winter 1997 Final Examination   (Site not responding. Last check: 2007-10-21)
Because each system call is executed by a user process in the "upper kernel" (in privileged mode), the system call can block waiting for a resource, without blocking other processes that seek to enter the same operating system component (such as the file-system).
Note that the Minix file server is single threaded; that is, it can handle only one request message at a time.
Therefore, if a user process requests an operation that results in the file server task blocking on reply from another task, no other process can request operations from the file server until the reply is received and handled.

If this fails, then you can locate the process id's of the Minix simulator with the syschecks command and then kill them with the kill -9 pid1 pid2 command, where pid1 and pid2 are the process id's of the two processes.
Typically, the only things you lose are the files that you have previously sunread into the root file system - which are normally just binary executables, copies of which are in your normal Solaris directory (usually cop4600/src/tools).
Before restoring a backup of Minix, you must first reinstall a fresh copy of Minix, because minix_backup only copies files that were modified and not the entire Minix directory.

 Minix FS - Waikato Linux Users Group
The Minix FileSystem was the file system used by Minix, and was described in "Operating Systems: Their design and implementation" by AndrewTannenbaum.
The Minix File system was used a lot on floppies where it's overhead was low.
It's design also leant itself to being a file within the FileSystem of the host OperatingSystem when Minix was run as a process within another OperatingSystem.

If your system has a hard disk, you can start by using NFS then build a root file system on the disk and boot from that.
Note that the minix file system code in Linux is not endian-independant, so you can't build a minix file system image on an x86 machine and expect to read it on a PowerPC machine.

Solaris MINIX is a version of MINIX that runs as a user process on Sun 4s running Solaris 2.4 to 2.6 (and perhaps earlier releases of Solaris 2).
Also, it is possible for multiple users to log into a single instance of Solaris MINIX, and to connect multiple Solaris MINIX instances using a simulated ethernet.
Most of the changes are in the MINIX kernel, with the memory manager, file system, init, inet and user programs and function libraries largely unchanged.

The minix file system (method to organize files on a hard disk partition or a floppy disk) was the original file system for Linux, but has been superseded by the second extended file system ext2fs.
Be aware however that the file system of your root partition (the one containing the directory /) cannot be compiled as a module, and so this may be dangerous.
NOTE: the file system type as used by mount(1), mount(2) and fstab(5) is 'vxfs' as it describes the file system format, not the actual driver.
