When I did try it just that way, it failed completely. I created the |
28 |
structure, except that I put quotas on each of the subvolumes, and then |
29 |
I rsynced the files from my non-btrfs copies which I had to do offline |
30 |
using my grml cd, and when I rebooted back into the new arrangements, it |
31 |
was a mess. I also got advice from their mailing list that I might want |
32 |
separate pools and this is why I was wondering about lvm, since I don't |
33 |
want partitions again. |

How do |
38 |
you spend it? |
