Unfortunately not, you can only grow at the end, not the beginning. Now,
if this is LVM or md, there may be tricks you can play to move things about,
but that would require boundaries to align correctly.
You could do this (CAREFULLY):
o create a temporary partition at the end of the device,
o copy the reiserfs data into this partition
o remove the original partition which contained the reiserfs filesystem
o make a larger partition containing all the space except that in
the new end of device partition, and put xfs on it.
o copy the data from the temp partition into xfs
o remove the temp partition and extend the xfs partition to the full
device
o run growfs
I wish I had a simpler suggestion! I have done this type of thing, but not with
that much data. Moving the reiserfs filesystem might be faster at the block
level or the filesystem level (i.e. dd or cp -r) depending on how full it is.
