I added a fourth drive to a RAID 5 array. After some complications
related to adding a new HD controller at the same time, and thus
changing some device names, I re-created the array and got it
working (in the sense "nothing degraded"). But size results are
weird. Each component partition is 320 G, does anyone have an
explanation for the "Used Dev Size" field value below? The 960 G
total size is as it should be, but in practice Linux reports the
array only having 625,019,608 blocks.
I don't see that number below, what command reported this?
For instance df:
$ df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/md0 625019608 358223356 235539408 61% /usr/pub
How can this be, even though the array should be clean with 4 active
devices?
df reports the size of the filesystem, mdadm reports the size of the array.
