[RegExp] Why my re works like this?

[Magicloud Wang]

Dear,
I have text like below, and re is as below. The result is as below.
Why the first result do not have the line with number '1'? It should like:
["/dev/hda", "gpt", " 1 17.4kB 64.0MB 64.0MB ext3 boot
\n", " 2 64.0MB 8590MB 8526MB lvm \n"]

Thanks.

--- the result
["/dev/hda", "gpt", " 2 64.0MB 8590MB 8526MB lvm
\n"]
["/dev/mapper/vgroot-lvroot", "loop", " 1 0.00kB 7449MB 7449MB xfs
\n"]
["/dev/mapper/vgroot-lvswap0", "loop", " 1 0.00kB 1074MB 1074MB
