<118>     [1mdumpfs[m -- dump file system information
<118>
<118>[1mSYNOPSIS[m
<118>     [1mdumpfs[m [[1m-f[m] [[1m-m[m] [7mfilesys[27m | [7mdevice[27m
<118>
<118>[1mDESCRIPTION[m
<118>     The [1mdumpfs[m utility prints out the super block and cylinder group informa-
<118>     tion for the file system or special device specified, unless the [1m-f[m or [1m-m[m
<118>     flag is specified.  The listing is very long and detailed.  This command
<118>     is useful mostly for finding out certain file system information such as
<118>     the file system block size and minimum free space percentage.
<118>
<118>     If [1m-f[m is specified, a sorted list of all free fragments and free fragment
<118>     ranges, as represented in cylinder group block free lists, is printed.
<118>     If the flag is specified twice, contiguous free fragments are not col-
<118>     lapsed into ranges and instead printed in a simple list.  Fragment num-
<118>     bers may be converted to raw byte offsets 
<118>by multiplying by the fragment
<118>     size, which may be useful when recovering deleted data.
<118>
<118>     If [1m-m[m is specified, a newfs(8) command is printed that can be used to
<118>     generate a new file system with equivalent settings.

<118>[1mNAME[m
<118>     [1mswapon[m, [1mswapoff[m, [1mswapctl[m -- specify devices for paging and swapping
<118>
<118>[1mSYNOPSIS[m
<118>     [1mswapon[m [1m-aq[m | [7mfile[27m [7m...[27m

<118>
<118>[1mDESCRIPTION[m
<118>     The [1mswapon[m, [1mswapoff[m and [1mswapctl[m utilities are used to control swap
<118>     devices in the system.  At boot time all swap entries in [7m/etc/fstab[27m are
<118>     added automatically when the system goes multi-user.  Swap devices use a
<118>     fixed interleave; the maximum number of devices is specified by the ker-
<118>     nel configuration option NSWAPDEV, which is typically set to 4.  There is
<118>     no priority mechanism.
<118>
<118>     The [1mswapon[m utility adds the specified swap devices to the system.  If the
<118>     [1m-a[m option is used, all 
<118>swap devices in [7m/etc/fstab[27m will be added, unless
<118>     their ``noauto'' option is also set.  If the [1m-q[m option is used informa-
<118>     tional messages will not be written to standard output when a swap device
<118>     is added.
<118>
<118>[7m--More--(byte 1329)[27m[K
<118>[K
<118>     The [1mswapoff[m utility removes the specified swap devices from the system.
<118>     If the [1m-a[m option is used, all swap devices in [7m/etc/fstab[27m will be removed,
<118>     unless their ``noauto'' option is also set.  If the [1m-q[m option is used
<118>     informational messages will not be written to standard output when a swap
<118>     device is removed.  Note that [1mswapoff[m will fail and refuse to remove a
<118>     swap device if there is insufficient VM (memory + remaining swap devices)
<118>     to run the system.  The [1mswapoff[m utility must move swapped pages out of
<118>     the device being removed which could lead to high system loads for a
<118>     period of time, depending on how much data has been swapped out to that
<118>     device.
<118>
<118>     The [1mswapctl[m utility exists primarily for those familiar with other BSDs
<118>     and may be used to add, remove, or list swap devices.  Note that the [1m-a[m
<118>     option is used differently in [1mswapctl[m and indicates that a specific list
<118>     of devices shou
<118>ld be added.  The [1m-d[m option indicates that a specific list
<118>     should be removed.  The [1m-A[m and [1m-U[m options to [1mswapctl[m operate on all swap
<118>     entries in [7m/etc/fstab[27m which do not have their ``noauto'' option set.
<118>
<118>     Swap information can be generated using the swapinfo(8) utility, [1mpstat[m
<118>     [1m-s[m, or [1mswapctl[m [1m-l[m.  The [1mswapctl[m utility has the following options for
<118>     listing swap:

<118>
<118>[1mDESCRIPTION[m
<118>     The [1mdumpfs[m utility prints out the super block and cylinder group informa-
<118>     tion for the file system or special device specified, unless the [1m-f[m or [1m-m[m
<118>     flag is specified.  The listing is very long and detailed.  This command
<118>     is useful mostly for finding out certain file system information such as
<118>     the file system block size and minimum free space percentage.
<118>
<118>     If [1m-f[m is specified, a sorted list of all free fragments and free fragment
<118>     ranges, as represented in cylinder group block free lists, is printed.
<118>     If the flag is specified twice, contiguous free fragments are not col-
<118>     lapsed into ranges and instead printed in a simple list.  Fragment num-
<118>     bers may be converted to raw byte offsets 
<118>by multiplying by the fragment
<118>     size, which may be useful when recovering deleted data.
<118>
<118>     If [1m-m[m is specified, a newfs(8) command is printed that can be used to
<118>     generate a new file system with equivalent settings.

<118>[1mNAME[m
<118>     [1mrc.conf[m -- system configuration information
<118>
<118>[1mDESCRIPTION[m
<118>     The file [1mrc.conf[m contains descriptive information about the local host
<118>     name, configuration details for any potential network interfaces and
<118>     which services should be started up at system initial boot time.  In new
<118>     installations, the [1mrc.conf[m file is generally initialized by the system
<118>     installation utility, sysinstall(8).
<118>
<118>     The purpose of [1mrc.conf[m is not to run commands or perform system startup
<118>     actions directly.  Instead, it is included by the various generic startup
<118>     scripts in [7m/etc[27m which conditionalize their internal actions according to
<118>     the settings found there.
<118>
<118>     The [7m/etc/rc.conf[27m file is included from the file [7m/etc/defaults/rc.conf[27m,
<118>     which specifies the default settings for all the available options.
<118>     Options need only be specified in [7m/e
<118>tc/rc.conf[27m when the system adminis-
<118>     trator wishes to override these defaults.  The file [7m/etc/rc.conf.local[27m is
<118>     used to override settings in [7m/etc/rc.conf[27m for historical reasons.  See
<118>     the [7mrc_conf_files[27m variable below.

<118>             ble only with the [[1m-v[m] option.
<118>
<118>     [1m-c[m      Clear the dump, so that future invoca

<118>     [1mdumpon[m -- specify a device for crash dumps
<118>
<118>[1mSYNOPSIS[m
<118>     [1mdumpon[m [[1m-v[m] [7mspecial_file[27m
<118>     [1mdumpon[m [[1m-v[m] [1moff[m
<118>
<118>[1mDESCRIPTION[m
<118>     The [1mdumpon[m utility is used to specify a device where the kernel can save
<118>     a crash dump in the case of a panic.
<118>
<118>     Calls to [1mdumpon[m normally occur from the system multi-user initialization
<118>     file [7m/etc/rc[27m, controlled by the ``dumpdev'' variable in the boot time
<118>     configuration file [7m/etc/rc.conf[27m.
<118>
<118>     For most systems the size of the specified dump device must be at least
<118>     the size of physical memory.  Even though an additional 64 kB header is
<118>     added to the dump, the BIOS for a platform typically holds back some mem-
<118>     ory, so it is not usually necessary to size the dump device larger than
<118>     the actual amount of RAM available in the machine.
<118>
<118>     The [1mdumpon[m utility w
<118>ill refuse to enable a dump device which is smaller

Comment 1 Etienne Robillard 2010-04-19 20:37:37 UTC

Hi,

I have an issue running the rt2870 module with a Trendnet TEW-644UB, 
can this be fixed using a native FreeBSD driver or the one provided in Git
is the most current ? (it seems not to have such driver available in 8.X.)

Alternatively, would there be a workaround to apply for using this card
with FreeBSD 8 ?

Thanks!

If you use out-of-tree driver, shouldn't you report this issue to the author of
the driver?

State Changed
From-To: open->closed

The problem seems to be with a driver maintained outside 
of FreeBSD source tree. 
Feedback timeout too.
