Hello,
We have a customer with a cluster factor of 1 on his disk, but his
shared mail area files all appear to have more blocks allocated
than needed. An example of size would be 1/3. Does ALL-IN-1
override the cluster size for the disk and pre-allocate a specific
number of blocks?

No,
The disk cluster size is out of the control of ALL-IN-1. You are
probably better off asking this question in another notes file - such
as VMSDEV::VAXNOTES.
There is a minimum cluster size for disks. This is calculated by
(disk size in blocks)/255*4096. Your disk might have a mimimum of 3
anyway.

Hello again,
The problem seems to be localized to ALL-IN-1 mail files. Any
files created in another way (EDT, COPY...) get a uesd/alloc
with matching values. (as is to be expected with a cluster
size of 1) The ALL-IN-1 mail files though, have 1/3 as their
used/alloc values. Is there a preallocation aspect to the
ALL-IN-1 mail? Since the user cannot modify the files, there
is no chance for further extension, therefore no need to allow
for the extension in a contiguous manner. I have gone over this
with VMS support, and they have determined that there is no
strange activity in respect to the VMS side of things.
Derek.

I've checked the code on this. The size is preallocated to be the size
of the original file. So if the user disks have a cluster size of 3
then this will be carried over to the size of the file when it is
copied to the shared area. If it's any comfort to you, you are not
wasting 66% of your space but only 50% as the file header requires one
block.
