I am setting up my first toaster - an F720 with one shelf (seven 36GB drives). I'm seeking some "real-life" experiences and recommendations based on what I am trying to do.
I work in a small office with approximately 50 employees and utilize UNIX and NT operating systems. I currently have several $HOME, $PROJECT, and GIS-related filesystems residing on my UNIX system. I plan to move these filesystems to the filer, but will be unable to create a separate volume for each filesystem. I considered creating two raid-groups, one for $HOME and one for $PROJECT, but I think there will be a performance hit (only 1-2 data disks per volume) and it will cost me two drives for parity, not to mention the spare disk drive. I am now looking at employing one large volume (the root volume) and establishing Qtrees to establish and manage HOME, PROJECT, and GIS areas within this volume, which would require NFS and CIFS access. I am also considering the idea of creating an additional Qtree to maintain user's roaming profiles for the NT environment - which would require CIFs access only. I don't like the idea of doing this all in one volume (especially /vol/vol0), but it looks as if this is the route I will be taking unless someone has a better recommendation. Finally, how difficult, or is it even possible, to remove a Qtree? I didn't find anything in the SA Guide to do this.
Thanks, Loren
I see no problem with doing it in all one volume. You won't have any preformance limitations. You do not even have to use qtrees if you don't want to, just different directories. But the qtrees help if you want to quota them to restrict space usage as if they were partitions.
As to removing a qtree it's really easy; you just delete it like any directory.

Qtrees are the preferred way to organize things for any application where you can't justify a separate volume. With one shelf, I'd recommend you have a single 6-drive volume and one hot spare. You can delete qtrees like any other folder/directory.
