 |
|
Hi all,
I finally rebooted my desktop system today after a couple of months of uptime. However, when I did I found that all of my drive entries in /dev had disappeared, namely /dev/sda* and /dev/sdb*. However, /dev/sda2, my / partition was mounted, so I can log in and use the system.
There may have been a couple of warning messages upon booting up (the OpenRC stuff, suffixed by other [ OK ] or [ !!], but I have been unable to find out how read them (they are not given by dmesg).
dmesg, however, does give:

But nodes for them do not exist in /dev.
I am running a 2.6.31 kernel under ~AMD64. Advice appreciated.
Regards, Freddie. |

| Use rc-status to check which services did not start. |

Well, I'd check full syslog first, then followed it with 'udevadm info' on the device
and checked /sys/block too. |

The same here. After a full emerge update, the /dev/sda* has disappeared.
Everything seems to be ok, however I can't see such devices.
Is there something to do with the evdev??
