This I don't know. I use this value for large partitions of multimedia data, |
| 17 |
because I do not want to waste space (no matter how big the drives are, mine |
| 18 |
are always quite full), and performance should not be a big issue here. I |
| 19 |
keep the 5% default other partitions, like /home. BTW, you can also specify |
| 20 |
fractions like 0.5% if you like. |

Another thing: Be sure to have enough inodes on the file system, I have run |
| 23 |
out of them in the past. Not only once. |
| 24 |
Other than the percentage of reserved blocks, which can be changed with |
| 25 |
tune2fs -m, this value is fixed. If you have too few, you need to re-create |
| 26 |
the file system. |
