Abstract
In one embodiment, a method of informing a mainframe that a filesystem storing a plurality of virtual tapes is filled relative to a particular threshold includes returning, responsive to a write request to a virtual tape in the filesystem, a message indicating that the filesystem is filled relative to the particular threshold. The method can also include monitoring a plurality of filesystems for free space remaining on each of the plurality of filesystems. The method can additionally include indicating, in a data structure stored in a memory, a particular filesystem that is filled above the particular threshold. The data structure can be at least one of a table and a list. The method can further include mounting, responsive to a request to mount a particular virtual tape that is on a filesystem indicated in the data structure as being above the particular threshold, the particular virtual tape as read-only.
