Hi: |

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: |
6 |
|
7 |
"Reserving some number of filesystem blocks for use by |
8 |
privileged processes is done to avoid filesystem |
9 |
fragmentation" |
10 |
|
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. |
