Hey Guys, thanks for the reply about the block stuff...
So if I run the dd command(s) you gave I get this output below...
Up to 512-bytes:All the way to 2048:
Is it safe to say here that the asterisks in the output above denote EMPTY space in that area of the disk..?
Also, so I'm clear on the sector/block size stuff.
If this below is the output for fdisk, and the START is 2048 and the UNIT size 512 bytes.
So for every "1 Unit" out of the 2048 START point, that would be: .5kb * 2048 = 1024 Kb... Is that right?
Thanks Again for the help, much appreciated!

No. There is no such thing as empty space on a character special file. The asterisk in the output from od means that the lines of output replaced by the asterisk are duplicates of the output shown on the line above. In this case, they all happen to be NUL bytes, but they could just as easily represent repeated occurrences of the characters "0123456789ABCDEF" (or any other sequence of 16 bytes).
I have a RHEL 5.3 machine with the following partitions and free space:
Free space on the partitions
/ : 74GB
/boot : 81MB
/var : 73GB
/home : 37GB
/icat : 758MB
/opt : 1.5GB
Now is it possible to allot a free space of some other partitions to /opt? I want around 100 GB more space... (4 Replies)
Hi
I'm doing some resilience testing and need to write a script to consume all of the available disk space on a partition and then to free it up again.
This would need to be -
Safe
Dynamic, in that it calculates the free space prior to consuming it.
I might want to go on to consume a... (7 Replies)
