Recovery Partition not being reported?

@JoySeeley What version of Jamf Pro are you running? If not for your comment about "Jamf is stating half of them" I'd guess you have an older version that isn't APFS aware.

I am running 10.8 as we are just getting up and running on it so it is a brand new install.

The disk encryption for the Macs that Jamf is stating don't have a recovery partition, is working, so I'm not sure why they are reporting they don't have a recovery partition. The keys are being stored on the server, so I guess it's working...

I am on Jamf 10.7.1 and my Mojave machines all report ineligible for encryption due to no recovery partition, even the ones that are already encrypted. I would blame APFS but the same problem does not appear on High Sierra APFS systems. I was thinking I would do the 10.8 upgrade and that would probably address it, but sounds like that may not do the trick.

I too am seeing this on 10.8

I'm glad to know I am not alone!! Now if we can find the solution.

I know this is a relatively old post, but I thought I would share my experience. Our machines on 10.13 and 10.14 in APFS format were not showing that a recovery volume / partition was present.

Like you, I ran a diskutil list and saw that /dev/disk1s3 was there as the Recovery Volume. I don't think the JSS is able to detect it or that particular portion of the machine inventory isn't getting granular with the available volumes in the container. Regardless, I decided to run a diskutil mount /dev/disk1s3 and then ran a recon. The JSS detected that the recovery volume was present. I've done this successfully with several machines showing the same behavior.

Why this happens, I don't know. But at least there's a bit of a workaround to get consistent reporting.

Hope this helps!

I have an Extension Attribute Script, that i use to report on the presence of a Recovery Partition.

Feel free to use it, you can find it here if you wish to download it.

I will post it below as well.

For what it's worth, I found this discussion because I noticed the same problem.

All of our Macs:

• Are formatted APFS, and
• Are running Catalina

Most of them are encrypted using a config profile. But even some of those don't show the recovery partition.

@Headbolt : Why does it matter if the Recovery partition is on 1 or 2?

Won't this always find it, no matter which disk it's on?

diskutil list | grep Recovery

I just tested it on my work Mac (2019 MBP running Catalina) and my personal Mac (2009 MPB running El Capitan) and it worked for both.

What am I missing here?
