Monitoring space in the TFS

The storage administrator or system programmer can monitor the space in a file system by mounting a file system with the FSFULL mount parameter. Status messages are issued as the system fills up. For example, by specifying mount parm('-FSFULL(70,10)'), message BPXTF009E is displayed when the file system is 70 percent full. Another message is issued when the file system is 80 and 90 percent full.

You can use the F OMVS,PFS=TFS,FSFULL command to change the default FSFULL value. This value applies to the subsequent TFS mounts that do not specify FSFULL.
