OK, interesting results. |

1) This system has worked for a couple of months. |
30 |
|
31 |
2) There was a small rainstorm here (SF Bay Area) on Tuesday |
32 |
afternoon. This had a bot of lightning and, according to the paper, a |
33 |
few peopl ehere were without power for 15 minutes. |
34 |
|
35 |
3) On Tuesday afternoon we started having problems. |
36 |
|
37 |
4) Looking at the logs on the NFS server I could see that it ha |
38 |
rebooted. That machine runs without a UPS. |
39 |
|
40 |
5) The switch is on that same plug with no UPS. |
41 |
|
42 |
6) Over the last couple of days I've rebooted the NFS server and the |
43 |
Myth backend server, all to better results. |
44 |
|
45 |
7) This evening I get the bright idea to reboot the switch. |
46 |
|
47 |
8) The switch now auto-negotiates and runs at 100Mb-FD: |

|

dragonfly ~ # mii-tool |
50 |
eth0: negotiated 100baseTx-FD, link ok |
51 |
dragonfly ~ # mii-tool -v |
52 |
eth0: negotiated 100baseTx-FD, link ok |
53 |
product info: vendor 00:00:00, model 0 rev 0 |
54 |
basic mode: autonegotiation enabled |

The switch was stuck in some strange state. Power down and back up fixed it. |
62 |
|
63 |
Time to get a UPS for the media center... |
64 |
|
65 |
Thanks for the invaluable help with mii-tool. Very, very helpful. |
