Not sure how I did this, but it happened before I upgraded to tumbleweed a couple of months ago, but I only noticed it now. On the partition in question, I had opensuse 42.2 installed, so I went in, changed all my repositories to tumbleweed, and did an online upgrade, and have been operating like that ever since.

First, I didn't know this was even possible, but apparently it is, because my system is running with partition 2 as the root drive.

It's very much possible - I'm not sure how much the partition type is really used anymore, but it certainly does not dictate which file systems you can use on a partition.

...

My first question is, is this likely to cause problems, and what kind of problems?

No and none.

...

My 2nd question is, how important is it to migrate my root over to another partition right away?

Not important at all. YOu could just use fdisk to revert the partition type to 0x83. -- Per Jessen, Zürich (21.4°C) http://www.hostsuisse.com/ - virtual servers, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I think under linux no application take care of this. It happened to me when reformatting in ext4 previous windows partitions jdd -- http://dodin.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I've seen these symptoms cause problems with upgrades - YaST (rightly) gets very confused about the Microsoft partition which it will normally avoid because it knows it's not a linux partition..but then it can't find the root partition to upgrade. IIRC the end result is a system that cant be upgraded without significant manual effort, unless the YaST team figured out a way of working around the issue because I'm pretty sure someone reported it before..at least I hope so.. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

It is actually YaST which sets up that incorrect partition type when it does the partitioning, since several versions. AFAIK it is harmless, except perhaps when running another year and trying to figure out autodetection of systems. It has been commented often enough, it must be a known issue to the YaST team. I think YaST does have a look inside all partitions to find out what they are. -- Cheers / Saludos, Carlos E. R.

Thanks everyone for your comments. Good to know that there is no immediate concern about this. I will fix it with something at some point in the future.

It is actually very simple: take any partitioner, say, fdisk, and change the type. No formatting. -- Cheers / Saludos, Carlos E. R. (from openSUSE 15.0 (Legolas)) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

MBR stands for Master Boot Record. Here, in a GPT formatted disk, I believe it is there to signal to other formatting utils that don't recognize a Global Partition Table, that the disk is formatted. I'm not sure if it contains actual boot code or not -- I tend to think it's there as a place marker to protect the GPT data. As far as I know, any partition can be a root partition. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I noticed this morning while setting up my backups, that it turns out the partition type is "Microsoft basic data" but the file system type is ext4.

It can contain bootcode, yes. It is the trick to make GPT disks bootable on old BIOS machines.
