It was the first thing I searched for in /etc/udev, but there weren't |
| 10 |
explicit pointers to dev, furthermore I have one only custom file |
| 11 |
in /etc/udev/rules.d: 10-local.rules, and the only other one I edited |
| 12 |
is 70-persistent-net.rules; they surely have nothing to do with md |
| 13 |
devices. |

After your second reply I did a crazy thing: moved /etc/udev to another |
| 16 |
position and reemerged udev. Then I diffed the two directories, because |
| 17 |
there were many files dated 2005 and 2006 not belonging to any |
| 18 |
packages. |

This cleanup wasn't enough, but then I edited /etc/mdadm.conf, modified |
| 21 |
the ARRAY directive |
| 22 |
|
| 23 |
from: |
| 24 |
ARRAY /dev/md0 level=raid1 num-devices=2 UUID=... |
| 25 |
|
| 26 |
to: |
| 27 |
ARRAY md0 level=raid1 num-devices=2 UUID=... |
| 28 |
|
| 29 |
I got some warnings at bootup, but no /dev/dev. |
| 30 |
|
| 31 |
Now I have no ARRAY directives in /etc/mdadm.conf, no /dev/dev and my |
| 32 |
system is more zippy than ever!! No more slowdowns on large file |
| 33 |
transfers: previously I was used to see transfer rate drop from initial |
| 34 |
peak to 8-10MB/sec, now the speed is constantly high.. |
| 35 |
|
| 36 |
Of course rkhunter is now happy about my configuration, as like as me! |
