i have not built any raid system in linux, but from reading, i saw
that there is a little difference from unix.
also, between linux flavors, there can be a lot of difference.
in a way, case of...
who wrote the book and how whoever is reading it.
ie, Slackware and CentOS.
looking at question of 'reporting', 'df' has various ways of reporting
size and might/may/could be what is causing difference.
so, until an exact reason/cause is replied...
besides '-h', what other arguments for 'df' did you try?
df --block-size=1000
df --block-size=1024
df --block-size=K
df --block-size=M
df --block-size=G
df --si
df -T
instead of reading
man df
have a look at
info coreutils 'df invocation'
you can also use 'lsblk', which i find it to be off a bit due to
how it rounds of sizes, except when using '-b'
'disk utility', 'system monitor', 'kde info center', 'gparted', are
other ways of viewing allocation.
much luck finding solution.
