How to find used space on RAW device?
Hi,

I'm trying to find out how to see used space on RAW device.
I tried with prtvtoc -f RAWdevice but for 3 different device I'm getting the same FREE_SIZE which look a bit impossible.

Code:
root@zg8cscfb1> prtvtoc -f /dev/md/redodg/rdsk/d300
FREE_START=0 FREE_SIZE=20352 FREE_COUNT=1 FREE_PART=
root@zg8cscfb1> prtvtoc -f /dev/md/redodg/rdsk/d301
FREE_START=0 FREE_SIZE=20352 FREE_COUNT=1 FREE_PART=
root@zg8cscfb1> prtvtoc -f /dev/md/redodg/rdsk/d302
FREE_START=0 FREE_SIZE=20352 FREE_COUNT=1 FREE_PART=
root@zg8cscfb1> prtvtoc -f /dev/md/oradg/rdsk/d406
FREE_START=0 FREE_SIZE=20352 FREE_COUNT=1 FREE_PART=

Can somebody tell me what exactly are FREE_START, FREE_SIZE, FREE_COUNT and FREE_PART.

Thanks
Mario

As it seems these devices are used by an Oracle database,
you could see their sizes from inside the database (see v$logfile/v$log, v$datafile and v$tempfile).
Note also that the allocated size could (and most probably will) be different than the actual used size,
if that matters in your case.
