Step 3.
Check the RAID rebuild status:
c c a a t t / / p p r r o o c c / / m m d d s s t t a a t t
Following is an example output:
Personalities : [raid1] [raid6] [raid5] [raid4] [raid0]
md123 : active raid5 dm-22[7](S) dm-21[6] dm-20[5] dm-19[4] dm-18[3] dm-17[2] dm-16[1] dm-15[0]
4657379328 blocks super 1.2 level 5, 16k chunk, algorithm 2 [7/7] [UUUUUUU]

md127 : inactive sdb[1](S) sda[0](S)
6306 blocks super external:imsm
unused devices: <none>
Step 4.
Check and calculate the completion time of the process.
As displayed in the example output from the previous step, the reshape process has a completion
time of 424.9 minutes (finish=424.9min). In hours, this is a little over seven (7) hours (424.9 minutes /
60 = 7.08 hours).
Step 5.
Wait until the completion time is up (in this example, more than seven (7) hours), and then check
that the process has indeed finished:
c c a a t t / / p p r r o o c c / / m m d d s s t t a a t t
Following is an example output:
Personalities : [raid1] [raid6] [raid5] [raid4] [raid0]
md123 : active raid5 dm-22[7](S) dm-21[6] dm-20[5] dm-19[4] dm-18[3] dm-17[2] dm-16[1] dm-15[0]
4657379328 blocks super 1.2 level 5, 16k chunk, algorithm 2 [7/7] [UUUUUUU]
bitmap: 0/6 pages [0KB], 65536KB chunk
