I have a two nodes cluster server. It is running on NW6.5 SP6. It is connecting a SAN storage There are two pools in the storage. Each pool has several volumes. When I add the directory quota in one volume, I get the error message "Unable to change directory space quota: /volume/user_folder. 255 was returned." Do I need to do the pool rebuild? Actually, I did it before I set the directory quota. It hasn't any error after the pool rebuild.

How can I solve it?

Thank you.
