looks promising: |

|
3 |
virt-backup dumps and packs a 12 GB image-file within ~145 seconds to a |
4 |
non-compressing btrfs subvolume: |
5 |
|
6 |
a) does a LVM-snapshot |
7 |
|
8 |
b) dd with bs=4M and through pigz to the target file |
9 |
|
10 |
The bigger LV with ~250GB is running right now. |

|

The system feels snappier than with the old kernel ... I wonder if there |
13 |
is more to tune as right now I am using the rather generic config which |
14 |
is not tuned for the specific CPU, for example (which might even have |
15 |
helped? ;-) ). |
16 |
|
17 |
That was good progress today ... but I might consider re-configuring the |
18 |
RAIDs as mentioned. |
19 |
|

As I run backups via amanda I have to provide a so called holding disk |
21 |
as intermediate place for dumps on their way to the tape drive. |
22 |
|
23 |
This means copying around stuff within the same hardware raid array. |
24 |
|
25 |
One big fat hw-RAID10 might be better? |
26 |
But losing the wrong 2 drives makes it crash again ... afaik. |
27 |
|
28 |
time for a break here. |
