This is a generic journalling layer for block devices. It is
|
||
|
|
currently used by the ext3 file system, but it could also be
|
||
|
|
used to add journal support to other file systems or block
|
||
|
|
devices such as RAID or LVM.
|
||
|
|
|
||
|
|
If you are using the ext3 file system, you need to say Y here.
|
||
|
|
If you are not using ext3 then you will probably want to say N.
|
||
|
|
|
||
|
|
To compile this device as a module, choose M here: the module will be
|
||
|
|
called jbd. If you are compiling ext3 into the kernel, you
|
||
|
|
cannot compile this code as a module.

If you are using the ext3 journaled file system (or potentially any
|
||
|
|
other file system/device using JBD), this option allows you to
|
||
|
|
enable debugging output while the system is running, in order to
|
||
|
|
help track down any problems you are having. By default the
|
||
|
|
debugging output will be turned off.
|
||
|
|
|
||
|
|
If you select Y here, then you will be able to turn on debugging
|
||
|
|
with "echo N > /sys/kernel/debug/jbd/jbd-debug", where N is a
|
||
|
|
number between 1 and 5, the higher the number, the more debugging
|
||
|
|
output is generated. To turn debugging off again, do
|
||
|
|
"echo 0 > /sys/kernel/debug/jbd/jbd-debug".
