What I mean is that e.g. in the output from df: /dev/vinum/sauron1 149118276 9447 137179367 0% /vinum the 149118276 (k) is the total size of the disk, whereas the 137179367 is the available space ( 149118276 - (8% of 149118276)). I was following the instructions in the Absolute BSD book which now that I've done it I think is confusing. > You're confusing Vinum and UFS. Vinum is a virtual disk. UFS is a > file system. It's UFS which reserves 8% or so of the file system (not > of the slice, which is a term which relates neither to UFS nor to > Vinum). If you reserve space on the disk and don't give it to Vinum, > Vinum doesn't use it. Period. Right. My confusion was on how to determine the size of the slice to stick into the vinum.conf file... According to Absolute BSD, the right thing to do is to read the 137179367 column, and use that value in vinum.conf. But obviously that isn't using the whole disk because it does not include the 8% of the drive that is set aside for root. In all the example vinum.conf files that I could find, there was a hard-coded size of the vinum drive. Now I think about it more it's obvious. I think. > That's because you haven't used all the space. If the drives are the > same, use 'length 0' for the subdisks and you'll get all the space in > the volume. Aha. I didn't know that you could set 'length 0', didn't see that documented anywhere. That solves all my problems since I don't need to determine the size manually now.
