Hello,
Since kernel 5.8.8, parted gives the following error message each time
parted attempts to modify something on the disk.
libparted 3.3
Partition(s) 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20,
21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38,
39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56,
57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74,
75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92,
93, 94, 95, 96, 97, 98, 99, 100, 101, 102, 103, 104, 105, 106, 107, 108,
109, 110, 111, 112, 113, 114, 115, 116, 117, 118, 119, 120, 121, 122,
123, 124, 125, 126, 127, 128 on /dev/sda have been written, but we have
been unable to inform the kernel of the change, probably because it/they
are in use. As a result, the old partition(s) will remain in use. You
should reboot now before making further changes.
In the example above, my disk contains 4 real partitions.
This bug appears on all the computers I have tried here.
Is this a new kernel feature or a parted bug?
Best regards.
Alain

I dug into this and it's a kernel bug that will be fixed in 5.9 rc5 as
well as backported to 5.8.10 so changing it in parted isn't the right
solution.
Thanks,
