XFS is good for a laptop as it is less likely to suffer a sudden failure |
| 11 |
than a desktop, the battery acts as a UPS. As long as you run some sort |
| 12 |
of battery monitor that shuts the computer down cleanly when battery |
| 13 |
levels become critical, power loss should not be an issue. |

However, it can be grown while mounted, something that is unsafe with the |
| 21 |
other filesystems, and something the OP asked for. |

That's not correct. resize_reiserfs can shrink as well as grown, but the |
| 27 |
filesystem must be unmounted. |
