The TFS is a physical file system driver the same way zFS and HFS are. The difference is that TFS is a memory only file system driver while zFS and HFS are both DASD file system drivers. Neither of them needs one of the others. They're independent. HFS was the original DASD driver and is being replaced more and more by zFS. Data is persistently stored in DASD data sets. TFS uses the private area in the address space to store the data. Data is lost when a TFS file system is unmounted. Have a look at the "confighfs" and "zfsadm grow" commands in the z/OS UNIX command reference and in the DFS zFS Administration Guide, resp., to learn how to increase the size of an existing HFS or zFS file system, even while it is mounted. -- Peter Hunkeler Credit Suisse ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
