Just added ten more Terrabytes to the Xsan. When republishing the volume via afp on a OS X 10.4 server box I had to:
sharing -a /path/to/volume
serveradmin stop afp
serveradmin start afp
Things that are not obvious in this:
The path in the sharing command can not end in a slash. But the shell WILL add it if you let it finish it.
The stop / start is needed. sharing -l will show the new volume but clients can not mount it.
Another neat trick that I learned today is that you have to slice an Xraid into 2 LUNs in order to overcome an internal 2 Terrabyte limit of the Storenext *cough* Apple Xsan software. That alone gave us an unexpected 2.7TB boost.
