Again, as mentioned in the original, the problem isn't quotaing the whole VPS, the problem is software (in this case, plesk) that seems to have a requirement to set a hard quota *within* the VPS itself, which isn't supported, currently, by jails ... In the past, for quotaing 'the whole VPS', I had tried the whole md(4) device idea, but found that insufficent inodes were being created for to do much, and no matter what I tried with newfs, couldn't seem to get more to be created, as if, due to the small size of the device, a 'max ratio' was being hit ... but, this was way back on 4.x when I tried that ... - ---- Marc G.
