RAW disk partition: chunk manager src?

RAW disk partition: chunk manager src?

Post by Curt Smi » Mon, 08 Jan 1996 04:00:00


We'er starting a project for a cluster DEC Alpha box environment using the
Beta release of DEC's clusters for Unix features.  One of the features is
a distributed raw disk (DRD) that's highly available even if boxes in the
cluster fail.  Unfortunately it's just a raw disk. ;-(

I've got a project to overlay  simple file/chunk manager API for a
RAW disk partition.  All I really need is a similar function to malloc(),
that returns a lseek value into the opened file descriptor to the
raw character device for this disk partion.

Any ideas and thoughts are welcome.

1. Partition Software - Partition Magic, Bootit, Boot Manager or Ranish Partition Manager

spake unto us, saying:

By default, Solaris and Linux will not be able to see each other, and
the Windows flavors will not be able to see either one.  So your only
concern will be the visibility between NT and Win95.

If you install those two in primary partitions on the same drive, there
shouldn't be a problem with that either.

Bootit is a utility I know of but have not used.

The only "Boot Manager" I know about is the OS/2 Boot Manager (also the
same as the IBM Boot Manager included as part of Partition Magic 3.x),
and it's a nice basic boot menu, but I'm not sure it's available at all
as a separate product.  I've used it for years (since 1992 I think).

Partition Magic is a glorified (and relatively powerful) fdisk utility
which I've used for quite a while.  Very useful, IMhO.  Newer versions
have things I'm not familiar with (I'm still using the OS/2 version of
PM 2.03).

Ranish's Partition Manager looks like a REALLY slick utility, and it's
on my list to play with.  But I copped out and bought a copy of System
Commander here instead.  :-)

I think I would recommend that you add System Commander to your list
above, since it allows you to selectively change primary partition
visibility (in many cases) for each individual boot menu entry.

Really, though, you probably don't need it.  The only question I would
have is how to get NT's boot manager to get along with Solaris' boot
manager, and I suspect that can be done.


       OS/2 + Linux (Slackware+RedHat+SuSE) + FreeBSD + Solaris +
        WinNT4 + Win95 + PC/GEOS + Executor = PC Hobbyist Heaven!
