Re: [linux-lvm] Kernel PANIC after partition change on RedHat 8.0



I have installed Red Hat Linux 8.0. I've made volume group (rootvg)
from /dev/md1 (which is raid1). I've put my /boot on /dev/md0.

As you already have noticed - I have two disks.
After installation I'm making new partiotion /dev/sdb5 i.e.
And if I change its to type to 8e after reboot kernel panics.
If I change type of this partition to something different - the system
boots fine.

I cannot understand where can be the problem.
I have to say that I made the same configuration on this machine and
everything was ok. But now I cannot see any difference.

sdb5 => sub-partition. Are you accidentally carving out a piece of an existing PV? For example, if you had partitioned the disk into /dev/sdb[1234] when it was built with sdb4 taking up most of the device as 8e (i.e., for LVM), then adding sdb5 w/in the area of sdb4 would certianly break things -- and scramble your LV's during pvcreate on the new partition.
