Gary,

I'm not clear on what you are intending by the partitioning you described so I'll tell you how I
have partitioned my hard drives under LVM. Maybe that will answer some of your questions.

I have two 120 gig drives; one as "primary" worker and the other as a backup. (I use dsync in a
manual mirroring method.)

Disk 1:
boot manager
C: is 10 gigs JFS and holds applications
D: is 50 gigs JFS and holds data
E: is 1 gig HPFS and holds eCS 1.1
L: is 1 gig fat16 and holds log files
N: is 1 gig fat16 and holds memory dump on a crash (must be at least as big as RAM)

Disk 2:
M: is 1 gig HPFS and holds eCS 1.1 mirror
P: is 10 gigs HPFS and holds applications mirror
Q: is 50 gigs HPFS and holds data mirror

The rest of the space on both drives is free space. And, yes, you can allocate it and deallocate it
as necessary. I did that when I had a bad crash and decided to redo my partition allocations. I
allocated some space from free space, saved files there, redesigned my partitions, restored the
saved files, reinstalled eCS via the mirror, and then returned the "save" partition to free space.

The drive lettering was assigned by me not by LVM.

I can boot to either E: or M:. This is not ideal though. Drive M: is a mirror of E: and that means
I have to fiddle with config.sys to boot properly in M:. I intend to create a true maintenance
partition on disk 1. Maybe on disk 2 also now that I think of it just in case drive 1 goes south.
(I've had a computer of one kind or another since 1977 and have not had a hard drive fail with out
notice, though.)
