Hi all! To all your FS guru's outthere, I desperately need to know where the disklabel is stored (since my disk is in trouble!)
Situation:
My /dev/ad0s1 has 2 partitions: "a" (FS) followed by "b" (swap). By using "disklabel -r", I see my "a" and "b" indeed take up the entire slice.
My desperate question:
Where, then, is the "disklabel" stored?
Somewhere in the partition table? The Master Boot Record? The reserved cylinder #0?
Or is it stored somewhere inside /dev/ad0s1a ?? (if that's the case, does that mean the UFS1 intentionally left some space unused, for this purpose? And if so, is it always at a fixed location within a UFS1 slice?)
What if in my slice, I have SWAP first, and then UFS1, then does that mean the SWAP Format also reserves some unused space for the disklabel to go???
Sorry if the question is stupid. I just somehow couldn't logically see where it would be stored, and yet be compatible with having other OS on the same drive... etc.
Thanks!
- Carl
