Seeing as vinum stores it's configuration data at the start of the vinum drive, I think it's not likely to work. You might get away with moving the data with dd, if you set your blocksize to sector size (or at least to a divisor of the spare space you allocate at the front). I wouldn't want to test this without good backups though, and at that point it might be easier to just recreate your vinum stuff from scratch and restoring anyway. > > >Even more likely to work is just adding another BSD partition on your > > >bigger drive, add that as a new vinum drive and then add > > >subdisks/plexes on top. > > > > That's the way to go, but just make sure you have only one vinum drive per > > disk. > > I have more than one vinum drive per disk and thats why I'm asking about > growing vinumized partition to get rid of other than one of them before > upgrading from 5.2.1 to 5.3. Why is more than 1 vinum drive per disk not good? --Stijn -- Apparently, 1 in 5 people in the world are Chinese. And there are 5 people in my family, so it must be one of them. It's either my mum or my dad...... or maybe my older brother John. Or my younger brother Ho-Cha-Chu. But I'm pretty sure it's John.
