Hi,
I have an ssa filesystem to move to san. We don't want any downtime. I heard that you can do a mirroring of existing file system on the san. The file system is a type of either raid 0, raid 1, or raid 5.
Anyone know how to do this?
Thanks in advance,

EMPTY-PAGE(1) ExactImage Manual EMPTY-PAGE(1)
NAME
empty-page - empty page detector of the ExactImage toolkit
SYNOPSIS
empty-page [option...] {-i | --input} input-file
empty-page {-h | --help}
DESCRIPTION
ExactImage is a fast C++ image processing library. Unlike many other library frameworks it allows operation in several color spaces and bit
depths natively, resulting in low memory and computational requirements.
empty-page counts dark pixels of a black and white image and decides with a threshold whether the page is most probably empty, and thus can
be removed from the image processing stream.
OPTIONS
-i file, --input file
Read image from the specified file.
-m n, --margin n
Set width of border margin to skip. For speed reasons, the margin has to be a multiple of 8. The default is 16.
-p x, --percentage x
Set fraction of permissible dark pixels. The default is 0.05 (5%).
-h, --help
Display help text and exit.
EXAMPLES
$ empty-page -i test.tif
The image has 75461 dark pixels from a total of 1060992 (7.11231%).
non-empty
EXIT STATUS
The exit status is 0 if the image is mostly white, 1 otherwise.
