Method, system, and program for managing an out of available space condition

摘要

Disclosed is a system, method, and program for managing an out of available space condition. A mount command for a logical volume is received that identifies one or more physical volume pools to be subsequently used for pre-migration. It is determined that one or more of the physical volume pools have no physical volumes available for storing data. Data is prevented from being written to cache by deferring completion of the mount command until the determined one or more physical volume pools has one or more physical volumes available for storing data.
