If it is an ext4 filesystem, then a newly formatted ext4 gets
background activity building some sort of internal data structures.
It eventually stops doing it if makes it all the way through. Possibly
other filesystems do something similar, but I know ext4 does.
Interesting. The array was mounted for many hours, but maybe not long enough.
Filesystem Size Used Avail Use% Mounted on
/dev/md127 55T 17T 38T 32% /new-raid
Seeing only 'write's suggests that it may be busy initializing some internal tables?
I will leave it mounted overnight (or longer). Naturally, once commissioned it will stay
mounted for years.
