Yes, that subject line is scary, but hear me out...
Yesterday, one of our clients reported in with the SMART status "Failing." Of course, I went defcon-1 and immediately insured that I had a good backup in anticipation of the worst. However, upon reaching the client and verifying the disk through Disk Utility, the SMART status reports as "Verified," not "Failing." I ran recon and the client in question was removed from the "SMART status FAILING" smart group, with the JSS now showing the client's SMART status as "Verified." So, cautiously I've lowered my alert to Defcon-3.
Has anyone seen this type of behavior? I've never known SMART status to be anything but a one way street. This isn't like it had an external connected, but it was the actual on-board HD that the JSS reported as "Failing" when, evidently, it was not.
FWIW, I've seen SMART report bad/OK on a device over time. I don't think it's a great way to truly detect failing devices, but when I get one, I tell the client and make sure they are backing up. It's up to the Business Unit whether to replace a cheap HDD (or not so cheap SSD) that is failing. I usually recommend that a backup/low level format is done and then tests. Most of the time, the business will buy a new drive. If it's under warranty, then it goes to Apple or a service contractor.
It's 2016 now, but the JSS is still reporting false positives. I just visited 2 systems which were supposedly failing, but had a status of Verified. Running
sudo jamf recon
in the Terminal immediately cleared the Failing status and the computer left the Smart Group. @pearlin, now that you're at JAMF can you figure this out for us?
