This is normal. mdraid works at the kernel/device driver level. It will
keep doing its thing as long as the system is up. Even if you were to shut
it down, it would pick up where it left off upon rebooting. BTW, what you
are seeing is likely not a process, but rather a kernel thread. IIRC, the
ps command shows kernel threads by enclosing them in square brackets. For
example:
[galens@zinc ~]$ ps aux | grep raid
root 572 0.0 0.0 0 0 ? S< 2020 557:05 [md1_raid1]
root 577 0.0 0.0 0 0 ? S< 2020 1:47 [md0_raid1]
Galen,
Here I see
$ ps ax | grep raid
4289 ? S 0:18 [md0_raid1]
Regarding the type of RAID to use, and based on my limited understanding
of your goals, I think you just want a simple RAID1 array.
Yep. This is my second experience building a RAID1 array and the first one
was half the size of this one so I probably didn't notice the time involved.
Thanks for the lesson. As Eric Harrison told me about 25 years ago linux is
really quite simple: one operation, one tool. But, he warned, there are
thousands of tiny tools to learn.
Stay well,
Rich
