[linux-lvm] How to hide a "Linux LVM" partition away from Windows?

[Ignacy Gawedzki]

Hi everyone,

I've been looking for the answer for some time now and it is apparently
nowhere to be found, so I resolved to ask it here.

Somehow unexpectedly, Windows "sees" LVM partitions (partition type 8e) and
shows them in the explorer and in other places.  Of course it doesn't
understand the format and I don't have access to their contents from there,
but nevertheless it happens to offer a "format..." entry in the contextual
menu (brrrr... quite frightening!).  Obviously, LVM just doesn't care that
much about the partition type when it scans for PVs, so I could probably just
put something else here (e.g. Linux, 82).

I was just wondering whether anybody here could provide with some insight
about this (why doesn't Windows simply ignore these partitions or whether
there are better tricks to hide them from it).  I find it pretty useful to be
able to identify LVM PVs when using fdisk for example (curiously enough,
gparted doesn't understand the 8e type).

I've seen that, but I'm not sure it works reliably.  It seems more like a
cosmetic hiding, but I suspect any program might still easily access the
partitions (i.e. still not by directly reading the bytes on the block device).

Besides, it is rather annoying 1) having to do it for each partition by hand,
2) eating up drive letters for nothing and 3) to use with drive racks or other
removeable drives.

Great!  This was exactly what I was looking for.  Thanks. =)
