| run: |
| steps: |
| - Install OS on the SUT(system under test) and make sure it boots. |
| - Power off the SUT and install three extra hard drives(use sd[b|c|d] |
| here). The three hard drives shoud have the same mode, at least the |
| same capacity. |
| - Boot to OS and make sure mdadm utility installed. |
| - Create 'Linux RAID auto' partition on each of the three hard drives |
| by running the following steps. |
| - 1) "fdisk /dev/sdx" |
| - 2) Delete all existing partitions with fdisk command "d" |
| - 3) Create Linux raid auto partition with fdisk commands |
| "n -> p -> 1 -> enter -> enter -> t -> fd -> w" |
| - Run the following steps to test RAID5. |
| - 1) Remove the existing md0. Refer to md0 removing steps above. |
| - 2) "mdadm --create /dev/md0 --level=5 --raid-devices=3 /dev/sdb1 /dev/sdc1 /dev/sdd1" |
| - 3) Monitor '/proc/mdstat' to check if md0 created and running. |
| - 4) "mkfs.ext4 /dev/md0" |
| - 5) "mount /dev/md0 /mnt" |
| - 6) "echo 'RAID5 test' > /mnt/raid5-test.txt" |
| - 7) "mdadm --manage --set-faulty /dev/md0 /dev/sdd1" |
| - 8) "mdadm --manage /dev/md0 -r /dev/sdd1" |
| - 9) Verify that '/mnt/raid5-test.txt' is not damaged. |
| - 10) "mdadm --manage /dev/md0 -a /dev/sdd1" |
| - 11) Monitor the output of "mdadm --detail /dev/md0" and make sure |
| that md0 'rebuilding' can be finished. |
| - Remove the md0 by running the following steps. |
| - 1) "umount /dev/md0" |
| - 2) "mdadm --stop /dev/md0" |
| - 3) "mdadm --remove /dev/md0" |
| - 4) "mdadm --zero-superblock /dev/sdb1 /dev/sdc1 /dev/sdd1" |

| expected: |
| - RAID5 array creating, deleting and rebuilding are successful. |
| - When one disk of RAID5 array damaged or removed, no data loss. |
| - When faulty disk replaced with a new one, RAID5 array can be rebuilt. |
