1. A computer-implemented method, comprising:
- identifying, at a client device, a request for data by an application of the client device;
sending, from the client device to a first server, the request for the data;
suspending a performance of actions on the data by the application of the client device;
receiving progress information for a recall of the data via a message buffer of a network file system (NFS) protocol error code; and
presenting the progress information to the application of the client device.

14. A computer program product for managing recall delays within hierarchical storage, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, wherein the computer readable storage medium is not a transitory signal per se, the program instructions executable by a processor to cause the processor to perform a method comprising:
-
identifying, by the processor at a client device, a request for data by an application of the client device; sending, by the processor from the client device to a first server, the request for the data; suspending, by the processor, a performance of actions on the data by the application of the client device; receiving, by the processor, progress information for a recall of the data via a message buffer of a network file system (NFS) protocol error code; and presenting, by the processor, the progress information a status of a recall of the data to the application of the client device.

15. A computer-implemented method, comprising:
-
receiving, at a first server, a request for data from a client device; determining that the data has been migrated from the first server to a second server separate from the first server; initiating a recall of the data from the second server to the first server; identifying recall information associated with the recall of the data; calculating a recall duration, based on the recall information; and sending the recall duration and the recall information from the first server to the client device via a message buffer of a network file system (NFS) protocol error code. - View Dependent Claims (16, 17, 18, 19, 20)
