"-m" option default value is 5% (!) = 50 GB space. No minimal reserved
space is specified/recommended in man pages.
GParted allocated to file system 1.616% = 29.42GB (quite generous against
default 5%).
For NTFS, on the other hand, only 0.0067% were allocated = 122.66 MB.
I do understand that some space must be reserved for the super-user to
allow avoiding fragmentation + journal, etc. However the amount of space
reserved seems to me unreasonably high - 29 GB vs. 123 MB.
Yes, I can tinker the situation to some extent with other mkfs.ext4
options. But I do not know if the gain is worth of efforts.
Besides, since the drive will be used for backup, I do not want to
sacrifice the stability of the file system in order to preserve space
either.
So, the question is, to which extent and with what result can I tinker
with mkfs.ext4 options.
Thanks.
