Bug 34135 – hotplug: /dev/sda1 not created when smartmedia inserted in reader

• Status: RESOLVED INVALID
• Product: Gentoo Linux

[Description JoWilly 2003-11-22 14:06:36 UTC]

Hi,

When I boot up and no card is inserted in the card reader, the reader exists as /dev/sda, /dev/sda1 does not exist (if the card is inserted at boot if works)

When I insert a card, /dev/sda1 is not created, so I cannot mount it.

To get it to work (create /dev/sda1) I have to manually do an:

/etc/init.d/hotplug restart

(or reload one of the modules (usb-storage or sd_mod).

I expect the system to automatically detect the card when I insert it, without restarting hotplug.

I'm using the HP PSC 2410 printer/scanner/copier/fax/card-reader multifunction device.

You need to be more specific, as this might be an kernel issue - what kernel,
and other related info please ...

Thanks for your help.

Try using udev (emerge udev && reboot).  Note to add 'devfs=nomount' to
kernel parameters.

[Comment 4 Johannes Ballé 2004-02-23 03:05:34 UTC]

This might be a timing issue. I used to have the same problem. Specifically, when inserting a USB Drive into the USB bus (using the usb-storage driver), the module sd_mod would not be inserted.

Instead, I got a "how to add device type= at /sys/... ??" message in the logs. It was generated by the /etc/hotplug/scsi.agent script. I noticed also that, on a reboot (the USB drive already plugged in) the problem would not arise.

It seems just shortly after the usb-storage driver is inserted, the "type" file in sysfs is not available yet.

WORKAROUND:

Insert a "sleep 1" into /etc/hotplug/scsi.agent (right before the "TYPE=$(cat /sys...)" line.

=> Works for me

For completeness:

I'm using udev-017, hotplug-20040105, sysfsutils-0.4.0 and gentoo-dev-sources-2.6.3 with no devfs support.

This is not a hotplug issue at all.

If you are using udev you can add a rule using the NAME{all_partitions} style
for this device in order to create all partition files for this device.  See
the udev man page for info on how to do this.
