Anyone using the APFS file system ?

Can you post some screen shots?

APFS is new, and I'm kind of surprised that you could have four partitions, if in fact that is what you have. From reading about it, I would have suspected that converting the drive to APFS would have affected the entire drive and created four Volumes in one Container, but to be honest, I've not played with it enough to know what options exist. I may have to do some experimenting.

Going by only what I have read, I would have assumed the same thing. And unless I am not understanding what was done correctly, I didn't think it could even be done.

Have fun and good luck experimenting!!! And maybe let us know what you discover.

I won't bother as I can't even run Mohave on my 2011 iMac.

I believe James, created the partitions using HFS+, and the formatted them afterwards, at least, that's what his description sounds like to me?

Ok, maybe you need to read this: https://support.apple.com/guide/disk-utility/partition-a-physical-disk-dskutl14027/mac and https://support.apple.com/guide/disk-utility/partition-a-physical-disk-dskutl14027/mac and some of the links from inside those articles. Your terminology would seem to indicate that you have four old-style partitions, three of them set up as APFS with a Container and a Volume for that partition, and one set up for HFS+. And now you have on your internal drive a second Volume named "containeroinvert" with one file? Or is it a second "Macintosh HD" with one file of that name? In any case, I would open Disk Utility and see if your internal drive has more than one Volume in the Container, then look at the external drive to see if the partitions each have one Container and one Volume to see if that duplicate Volume is there. If so, follow the instructions from Apple in the articles and linked articles to eliminate the extraneous Volume.

BTW, your division of the drive was not really needed. It would have been easier to have just two partitions with one Container and three Volumes on one partition, then the other partition as HFS+. But in fact, you don't even need the HFS+ on the external unless you want to somehow share the drive physically with another Mac with an older version of the OS. The advantage of APFS and the Container/Volume structure is that volumes are dynamically sized within the Container, so the three drives would size themselves within the Container as they needed to as you added/removed files from the Volume.

I would guess it is quite obvious to all that I am not some high tech guru. I get things done usually the hard way and only then because I'm a hard nose that don't give up to easy. You say I didn't need to do it the way I did, but I found no step by step manual telling me how to do what I wanted and I found no one who knew any more about it that I do. I formatted the 4T drive into 4 1T volumes and installed APFS on 3 volumes to try the new file system and I left a 1T as the old file system so I could use it as a time Machine backup drive, and also be read by my old Mac Pro desktop on El Capitan. And actually every thing was going great until the lighting strike that cut the power. What I wanted was 5 drive icons on the desktop giving quick access to those drives and it worked I have it.

I really don't know the difference between partitions, containers, volumes, but I also seem to have all of those. Disk Utility says I have 5 containers and about 4 volumes...so at the moment I'm pretty much of a happy camper with the new iMac. Defiantly a bit of overkill for what I do anymore, but what the heck I'm 81 years old and this will probably be my last new computer...

Ok will see if I can get one or two and post em.

Yes the 4T drive was originally partitioned and formatted using the old file system, then when I hooked it to the new iMac I changed it APFS.

Here are a few shots of the system hope they help explain it...

How about one screenshot of Disk Utility with all partitions?

Oh by the way I finally figured out how to solve the problem of that extra Macintosh HD icon that needed to be "inverted". The answer was so simple I am amazed someone didn't spot it right off and jump in with the answer. Notice the top left corner of the disk utility above...see the + - ...simply hit the minus with it highlighted and poof it's gone.

Congratulations and good sleuthing.

I'm glad you found the solution, but I'll bet a member would have pointed out the solution if the image had actually being posted. I sure didn't see one, but maybe I just missed it somewhere previously or now.

PS: Was that perhaps the "disk2" that seems to be missing from the disk order in the screeshot???

Anyway, I'm glad to read you got your problems all sorted out and things now seem to be working well with that new iMac.

Ya I kind of wondered about #2 also, but no it was in #5 between Music and iMac but as you see it is gone now.

I think they all get renumbered when you reboot, so the number isn't significant. It's the mount order.
