I was ordered by my management NOT to make backups or
I would be fired (exact words). So, I didn't. I told everyone
concerned that we HAD to have backups and follow corporate
policy. Everyone said thank you and go away. So I did.

Actually, we had partial success and got back most data. Then
on a whim we tried the bad drive again, and BINGO it came back
to life! I tried every trick I know to get that drive back and spoke
with the vendor that agreed I did everything they knew how to
do. Then another admin walked in, popped it back in the case and
and it came back. I had the biggest egg on my face! Oh well, at least
we got the data back.

My manager at that time couldn't spell UNIX, doesn't have a college
degree of any type and has never taken a single college course. My lead
admin can only spell "Sun" even though he claims to have a Linux box at
home and is pretty much hated by all UNIX/Linux admins (as well as
most NT admins as well). He is the king of micro managers (and I have
seen plenty of these in the aerospace industry).

Thanks for the venting time and space. I apologize.

I like EVMS and it's concepts. However, I'm currently using LVM
(I learned LVM on HPUX, so it was trivial to move to LVM on
Linux!). So, I guess you could say that I started with LVM - like it,
use it, depend on it; moving on to EVMS after some experimentation
and testing. I hope the two  merge at some point to avoid
proprietary-isms that seem to be coming.

Plus, I'm interested in the Open Cluster Framework
developments with EVMS. I don't know if these kinds of
things are happening with LVM or not.
