You have to resize the "thing" on which the filesystem resides. In other |
11 |
words, this is the first parameter you would supply when mounting it. |
12 |
If your filesystem is a whole disk, then you resize the disk. If it's a |
13 |
partition, then supply the partition device node as parameter. Similar |
14 |
with LVM volumes, raid volumes or whatever other gadget your filesystem |
15 |
is on. |

resize2fs is quite smart, if you don't supply a size, it expands the |
18 |
filesystem to take up the entire device. Let's say the filesystem is |
19 |
on /dev/sda3, you would then just do: |
20 |
|
21 |
resize2fs /dev/sda3 |
22 |
|
23 |
Don't worry about unmounting the device or anything like that, growing a |
24 |
filesystem can be done live and on-line |
