Subject: [gentoo-user] ext4 reserved space and defragmentation?

1 Hi:
3 I want to tune my ext4 filesystem of NAS data partition to free its
4 reserved space by using "tune2fs -m0 <partition>". By reading the
5 manual of tune2fs, I observed the following words:
7 "Reserving some number of filesystem blocks for use by
8 privileged processes is done to avoid filesystem
9 fragmentation"
11 It means that filesystem defragmentation need such reserved blocks to
12 work properly, am I right? If so, can I make the reserved blocks a
13 little because the default 5% is too much. My NAS filesystem is about
14 7x1.5T, then 5% means a lot of space.
