Hi Yu kuai,
Looks the original issue starts to re-appear now with the two patches:
https://lore.kernel.org/linux-block/20221130135344.2ul4cyfstfs3znxg@quack3/
And underlying disk partition and raid partition can be observed at the
same time.
Can you take a look?
Follows the script, which isn't 100% triggered, but still easy.
#create level 1 with 2 devices, meta 1.0
mdadm -CR /dev/md0 -l 1 -n 2 /dev/sda /dev/sdb -e 1.0
#create partition 0, start from 0 sector, size 100MiB
sgdisk -n 0:0:+100MiB /dev/md0
#observe partitions
cat /proc/partitions
#stop the array
mdadm -S /dev/md0
#re-assemble
mdadm -A /dev/md0 /dev/sda /dev/sdb
cat /proc/partitions
Thanks,
Ming
