Hello, I'm back with another regression found in SLES15SP6. The scenario is as follows: 1.Create RAID 1 volume with native metadata. # mdadm -CR /dev/md126 -l1 -n2 /dev/nvme[0-1]n1 --assume-clean --size=5G 2. Create partition and filesystem on raid volume. # parted -a optimal /dev/md126 mktable gpt mkpart primary ext4 0% 100% -s # mkfs.ext4 -F /dev/md126p1 3. Remove device via "--incremental --fail". # mdadm -If nvme0n1 Result: Mdadm hangs and hung task info from mutliple components starts appearing on serial.
FYI, this is fixed by: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=855678ed8534518e2b428bcbcec695de9ba248e8
