+ | There are several reasons for splitting the users across multiple LUNs. | ||
+ | |||
+ | * If a LUN is moved offline (for resizing for example), only those users on that LUN are affected. | ||

+ | * If the filesystem goes corrupt, a file system consistency checks needs to be performed. | ||
+ | |||
+ | * Multiple LUNs allows us to group users together, so for example, we have a LUN for students performing class work and a LUN for postdocs/ | ||
