One single Raw Device should be holding only one datafile.
Normally, the datafile is created as the same size as the Raw Device
[minus the header block overhead].
However, you can use
1. dd if=rawdevice of=/dev/null bs=1M
and the count should show the size of the raw device.
2. query dba_data_files for the size of the Oracle Datafile in the raw device.
The difference should be the "free space" -- space which you can
resize/autoextend the datafile by.

Folks, Is there an equivalent to "df -k" to check space usage for RAW devices? If not then how can one look at the free space available on the RAW device? I am using RHL ES 4.
Thanks
