Hi, |
2 |
|
3 |
soon I'll be replacing the system disks and will copy over the existing |
4 |
system to the new disks. I'm wondering how much merit there would be in |
5 |
being able to make snapshots to be able to revert back to a previous |
6 |
state when updating software or when installing packages to just try |
7 |
them out. |
8 |
|

To be able to make snapshots, I could use btrfs on the new disks. When |
10 |
using btrfs, I could use the hardware RAID-1 as I do now, or I could use |
11 |
the raid features of btrfs instead to create a RAID-1. |
12 |
|
13 |
|
14 |
Is it worthwhile to use btrfs? |
15 |
|
16 |
Am I going to run into problems when trying to boot from the new disks |
17 |
when I use btrfs? |
18 |
|
19 |
Am I better off using the hardware raid or software raid if I use btrfs? |

The installation/setup is simple: 2x3.5" are to be replaced by 2x2.5", |
23 |
each 15krpm, 72GB SAS disks, so no fancy partioning is involved. |
24 |
|
25 |
(I need the physical space to plug in more 3.5" disks for storage. Sure |
26 |
I have considered SSDs, but they would cost 20 times as much and provide |
27 |
no significant advantage in this case.) |

I could just replace one disk after the other and let the hardware raid |
31 |
do it all for me. A rebuilt takes only 10 minutes or so. Then I could |
32 |
convert the file system to btrfs, or leave it as is. That might even be |
33 |
the safest bet because I can't miss anything when copying. (What the |
34 |
heck do I have it for? :) ) |

Suggestions? |
