This should have been easy but something seems out of whack. On SCO 5.0.6 I set up a system with 8 striped 38 MB drives. That should give me somewhere around 308 MB of disk space on the root drive. My df -v gives me 70,000,000 blocks. At 1/2 K per block I get 35,000,000 bytes, about the size of one drive. I've been in the controller setup many times and it shows all drives stripes and all drive lights light up during a read or write.
Hello,
If you're seeing one logical drive that's the same size as the individual physical drives that are its members, and you're seeing reads/writes on all physical drives when using the logical drive, then it sounds like all your physical drives are in a single RAID 1-style logical drive. In other words: your setup is mirroring-based, rather than striped. That's what it sounds like anyway, based on the behaviour you're reporting.

I'm seeing the one logical drive that I set up. The point is I'm only seeing about half of it I think. Basically I've forgotten enough SCO to forget how to go from blocks to MB . I need someone to double check my figures. df -t says 28367588 blocks. What's that in MB?
Hello,
That depends on your block size, really. Your filesystem would have been created with a fixed block size when it was initialised, and that block size would determine what the free block count corresponds to in bytes.
I believe SCO OpenServer should support the -k flag to df, and if so that will give you effective sizes in kilobytes. That might be the best way for you to get a pretty human-readable and clearly-understandable set of figures.
You will find that /etc/dfspace gives disk usage in an easy to read format,
divvy will show how file systems are allocated.
