I am a super-heavy duty kernel developer
with half a dozen file systems under my
belt. You really don't know who you are
talking to. I was one of the developers
of VxFS, and I managed two of the top
file system development teams in the
industry (Veritas and SGI).

You worked in support and you don't know
how to fsck a root file system ?!?!?!?!?

"/sbin/fs/vxfs/fsck -o full -y does a very
different kind of work than ufs or ffs fsck.

Not to mention that it is not obvious to
me that the advice you provided to your
customers was relevant.

File systems are tightly coupled with
the kernel, and they need to be kept
up to date every time the kernel is
patched. If you subtract the number
of kernel patches from the number of
VxFS patches, you will be left with a
much lower number.

VxFS is not perfect, nor are any other
journaling file systems perfect. That
does not mean that their transaction
mechanisms don't work.

VxFS is a file system *UNLIKE* any other
file system currently available in the
market place. No other file system that
I am familiar with comes even in design
quality (and I know a lot of file systems).

Can you provide hard numbers to back up
your statement?
