Holas, |

After a week or so of upgrading gcc, emerge -e world/system, watching hal/dbus |
4 |
toggle between +/- 0.5 versions, and having gentoo upgrade udev while I'm |
5 |
doing all this, I've finally got a clean, rebuilt system. |
6 |
revdep-rebuild gives comes up clean. |
7 |
emerge -autvDN world comes up empty. |
8 |
emerge -a depclean says I don't have to do anything. |

|

However, upon reboot, I can't get a USB backup drive to mount correctly. |
11 |
It's an LVM2 partition that should show up as vgusbhd, mounted to /mnt/usbhd. |
12 |
Something seems to die between vgscan finding the drive/partition, and udev |
13 |
creating a /dev/mapper/vgusb* mountpoint. It has no problem finding the |
14 |
other /hd* LVM2 partitions. Seems only the /dev/sda partition is missing. |
15 |
Of course, it's the only usb/sd* drive on the system. |
16 |

Reading all physical volumes. This may take a while... |

And the udev rule that seems to work, since there is a link |

As you can see, there is no /dev/mapper/vgusb. |

Trying to mount the drive directly to /dev/sda1 doesn't work, either |
49 |
|
50 |
crichton ~ # mount -t ext3 /dev/sda1 /mnt/usbhd/ |
51 |
mount: wrong fs type, bad option, bad superblock on /dev/sda1, |
52 |
missing codepage or other error |
53 |
In some cases useful info is found in syslog - try |
54 |
dmesg | tail or so |
55 |
|
56 |
|
57 |
crichton ~ # dmesg | tail |

VFS: Can't find ext3 filesystem on dev sda1. |

|
61 |
The drive has an ext3 fs on it. It worked until the reboot. But it's (as |
62 |
indicated) an LVM partition. |
63 |
|
64 |
crichton ~ # fdisk -l |

So, is there a simple command that will get me going? Everything I saw on |
74 |
Google says "upon reboot, you should have..." |
75 |
I don't. |

Thanks. |
