Title:
[VROC] Kernel panic during reshape - probably missing patch
Status in linux package in Ubuntu:
Confirmed
Bug description:
Bug found for Jammy (22.04)
Steps to reproduce:
1. Create 3 partitions with parted tool on initial non-RAID drive
# parted -s /dev/nvme6n1 mklabel gpt
# parted -s /dev/nvme6n1 mkpart primary ext4 0% 30%
# parted -s /dev/nvme6n1 mkpart primary btrfs 30% 60%
# parted -s /dev/nvme6n1 mkpart primary xfs 60% 90%
2. Create filesystem on each partition
# mkfs.ext4 /dev/nvme6n1p1
# mkfs.ext4 /dev/nvme6n1p2
# mkfs.ext4 /dev/nvme6n1p3
4. Create RAID container
# mdadm --create /dev/md/imsm0 --metadata=imsm --raid-devices=4 /dev/nvme6n1
/dev/nvme4n1 /dev/nvme2n1 /dev/nvme1n1 --run –force
5. Create RAID on drive with data
# mdadm --create /dev/md/volume --level=0 --chunk 64 --raid-devices=1
/dev/nvme6n1 --run –force
6. Make sure GPT data structures are in proper place
# sgdisk -e /dev/md/volume
7. Grow temporary RAID 0 volume with two devices. Wait for reshape end.
# mdadm --grow /dev/md/imsm0 --raid-devices=2
8. Grow temporary RAID 0 to RAID 10
# mdadm --grow /dev/md/volume --level=10

Recovery starts but frozen. Kernel BUG occurs:
