Skip, Are you sure they are unmounted? If you have separate UNMOUNT statement for each ZFS in the hierarchy and you try to unmount one higher in the hierarchy before the lower one, it will fail.
As of z/OS V2.2 you can safely use in UNIX shell: unmount -R /SERVICE That will unmount in proper order, everything at that mountpoint and below it. I have zero problems backing up any of my ZFS file systems with DFDSS. We are shared sysplex filesystem, in case that makes any difference _________________________________________________________________ Dave Jousma Mainframe Engineering, Assistant Vice President david.jou...@53.com 1830 East Paris, Grand Rapids, MI 49546 MD RSCB2H p 616.653.8429 f 616.653.2717 -----Original Message----- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@LISTSERV.UA.EDU] On Behalf Of Jesse 1 Robinson Sent: Wednesday, November 7, 2018 12:30 PM To: IBM-MAIN@LISTSERV.UA.EDU Subject: Re: Using FDR **CAUTION EXTERNAL EMAIL** **DO NOT open attachments or click on links from unknown senders or unexpected emails** And now for the rest of the story... [Some details in the interest of completeness. I'm truly not expecting] a DFDSS solution from the List. We've had an SR open on this since August, and IBM can't figure it out. The problem affects only 'maintenance' ZFS, which are never in use except during SMPE runs. Out of a dozen or so separate ZFS files, the same three always fail during DSS dump. This failure began with the first attempt under z/OS 2.3. Essentially the same job has run fine for years with earlier releases. More surprisingly, a rerun against z/OS 2.1 files (executed under 2.3) now show the same error for the 'same' three files. Logic is simple: 1. Unmount all related ZFS files with UNMOUNT commands, ending with ROOT. 2. DSS dump the now unmounted files using the 'DUMPIT' step posted below. 3. Remount the ZFS files. Three of the files now get an error during dump implying that they're in use even though they've been unmounted. What I'm looking for is a comparable FDR process to accomplish the same goal. It drives me crazy that Innovation does not provide online access to a user manual. I'm not a DASD guy even though I've played one at SHARE. . .

Believe me, you either want to quiesce or unmount the zFS before dumping it. Otherwise, you'll be waiting roughly 15 minutes for the mount operation to complete on the target/restoring system. - Vignesh Mainframe Infrastructure -----Original Message----- From: IBM Mainframe Discussion List <IBM-MAIN@LISTSERV.UA.EDU> On Behalf Of Vernooij, Kees (ITOPT1) - KLM Sent: 07 November 2018 07:29 To: IBM-MAIN@LISTSERV.UA.EDU Subject: [EXTERNAL] Re: Using FDR Can you reliably dump your zFS, with DSS or FDR, while it is active and being changed, with data cached etc., while being dumped? Innovation has FDR-Upstream for that. It dumps and restore individual files in the zFS.
