instead of a mass migration and upgrade as i'd originally contemplated, i've simply added a new disk array to my systems to add more space. i've moved many existing domains from the original filer to the new one, simply dropping a symlink in place at the original location - and everything works perfectly, which is great.
however, some of my biggest domains are the ones for customers who don't have their own domain. i'm probably not going to migrate those to the new filer, as the downtime while the data transfers would be too long. instead, i'd like to symlink the new numbered subdirectories of those domains to the new filer, so future growth will go there. my question is, can one 'pre-create' the numbered subdirectories, and will vpopmail use them properly, or does vpopmail have to create them itself for them to work?
In the past I've "precreated" these directories (actually had to once to make adding users work, still never figured that out) and they just get used. I believe that the vpopmail code checks the existence before trying to create, and if it exists it just uses it.
