We have bunch of Sun Sparc workstations(solaris 7 & 8) connecting to a linux file server with NFS exports. Recently we upgraded our file server from fedora core1 to redhat enterprise linux 4. And since then we are experiencing a nightmare of file/dir missing. It happens randomly, couple of times... (1 Reply)
We have a Slackware 9.1 box that our ASP controls. We use it to see the logging of our Weblogic-clusters.
All the logging is auto-mounted in /rmt which is fine, as long as you know the names of the mountpoints. When you don't access the mountpoints for a certain period of time, the mountpoint... (0 Replies)

mkfs
MKFS(8) System Administration MKFS(8)NAME
mkfs - build a Linux filesystem
SYNOPSIS SYNOPSIS
mkfs [options] [-t type fs-options] device [size]
DESCRIPTION
mkfs is used to build a Linux filesystem on a device, usually a hard disk partition. The device argument is either the device name (e.g.
/dev/hda1, /dev/sdb2), or a regular file that shall contain the filesystem. The size argument is the number of blocks to be used for the
filesystem.
The exit code returned by mkfs is 0 on success and 1 on failure.
In actuality, mkfs is simply a front-end for the various filesystem builders (mkfs.fstype) available under Linux. The filesystem-specific
builder is searched for in a number of directories, like perhaps /sbin, /sbin/fs, /sbin/fs.d, /etc/fs, /etc (the precise list is defined at
compile time but at least contains /sbin and /sbin/fs), and finally in the directories listed in the PATH environment variable. Please see
the filesystem-specific builder manual pages for further details.
OPTIONS -t, --type type
Specify the type of filesystem to be built. If not specified, the default filesystem type (currently ext2) is used.
fs-options
Filesystem-specific options to be passed to the real filesystem builder. Although not guaranteed, the following options are sup-
ported by most filesystem builders.
-V, --verbose
Produce verbose output, including all filesystem-specific commands that are executed. Specifying this option more than once
inhibits execution of any filesystem-specific commands. This is really only useful for testing.
-V, --version
Display version information and exit. (Option -V will display version information only when it is the only parameter, otherwise it
will work as --verbose.)
-h, --help
Display help and exit.
BUGS
All generic options must precede and not be combined with filesystem-specific options. Some filesystem-specific programs do not support
the -V (verbose) option, nor return meaningful exit codes. Also, some filesystem-specific programs do not automatically detect the device
size and require the size parameter to be specified.
