In the Admin Reference for v3.7 it says...

the allocated file size is always a multiple of 4MB plus an additional 1MB
ofr overhead).

Don't know how much that will help answer your question.

Thanks,
Jon

Subject: dsmfmt question


Hi *SM-ers!
I will replace my 9 Gb. SSA disks in the very near future. The new disks (36
Gb. 10.000 rpm) will have to be added to the diskpool one by one.
I remember from the last time that it was quite difficult to allocate a disk
file which fills the disk completely. If you have, for instance, a 9 Gb.
disk, you cannot create a 9 Gb. file by issuing a DSMFMT -G -DATA filename
9. This results in an error indicating the there isn't enough space
available. Apparently the dsmfmt utility needs a little bit overhead space.
Does anybody know how to calculate the maximum space one can specify to fill
the disk to it's maximum?
Thanks in advance for any reply!!!
Kindest regards,
Eric van Loon
