if I make sure all changes are flushed to disk, then I am OK.  However,
the responses I have received are not clear on what conditions caused
the problems.

I am also not clear on which kernel and what patches I need to make
sure that the filesystems (ext2,ext3 and reiserfs) will deal with the
VFS patches.

We run 24/7 systems and it is not an option to take down a system to=20
back it up.  We can handle slightly degraded performance, but even
that is a problem.

This is not what I understood from the HOWTO's and the SuSE whitepaper.
They are quite clear that you only need enough space to contain the
changes that occur while the snapshot partition exists. =20
