M-Net Downtime Status, August 23, 2002
| 
Aug 23 20:53 UTC 2002 |
Okay, new item.
M-Net crashed sometime around 2pm today. From what I can tell, we've
either got a corrupted filesystem, or the vinum filesystem is
corrupt. Either way, it's going to take some time to repair. I'm
unsure how it crashed. I think it just rebooted itself, as I was on
at the time and there were no shutdown messages.
Here is what I saw when I had it booting into a serial console:

When it gets to the firewall line above, it just hangs.
Needless to say, I'm going to run to WWNet later tonight and retrieve
the box so I can work on it.
Visit http://down.arbornet.org for more current information. I'm not
sure how often I'll remember to actually logon to grex.

Okay, good news and bad news.
The good news is that I've finally successfully repaired all of m-
net's partitions, including /bin/suid. I finally found out how to make
it work by reading more closely the man page for vinum, though it's
not clear exactly why it required what it did. Anyway, all the
partitions come up cleanly after they're fsck'd.
The problems arise when it attempts to start sendmail. At that point,
it kernel panic's with this:
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0x0
fault code = supervisor read, page not present
instruction pointer = 0x8:0xc0196c34
stack pointer = 0x10:0xc8bc8d0c
frame pointer = 0x10:0xc8bc8d14
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = 137 (sendmail)
interrupt mask = net
trap number = 12
panic: page fault
Possibly, sendmail is just corrupt. I'm going to try disabling
sendmail and starting the box up and see if I can get a login: prompt
then.
