 Posted: Tue Dec 13, 2005 2:33 am Post subject: HAL and /dev/sda |
 |
|
So, I've got a USB key that shows up on /dev/sda and /dev/sda1. Trouble is, when it's hotplugged, HAL gets an entry for "/dev/sda", but just doesn't see "/dev/sda1"--so gnome-volume-manager (or anything else that uses HAL for that matter) won't automount the device, because HAL's not seeing the actual partition.
Before anybody asks:
- I'm a member of the plugdev group.
- HAL and DBUS are both being started on boot.
- gnome-volume-manager is being started in my Gnome session
dmesg output on hotplugging:
| Code: |

/var/log/messages has the dmesg output, and adds the line from hotplug:
| Code: |

gnome-volume manager reports the following:

Which makes sense, because that device in HAL has block.is_volume = FALSE.
lshal | grep sda reports just one device (sorry for the nano line truncations),
| Code: |
udi = '/org/freedesktop/Hal/devices/storage_model_TD_Classic_003C'
info.addons = {'hald-addon-storage'} (string list)
storage.policy.should_mount = true (bool)

info.udi = '/org/freedesktop/Hal/devices/storage_model_TD_Classic_003C' (str$

linux.sysfs_path_device = '/sys/block/sda' (string)
linux.sysfs_path = '/sys/block/sda' (string)

With no device for /dev/sda1, just this device for /dev/sda.
Does anybody know what's going on here?
