 |
|
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
When I insert a card, /dev/sda1 is not created, so I cannot mount it.
To create /dev/sda1 I have to manually do an:
| Code: | /etc/init.d/hotplug restart
|
What can I do to get /dev/sda1 automatically created or statically existing (even if no card is in) ? |

| If it's USB, unplug the reader, insert a card, plug it back in. |

I had the same problem and I tried absolutely everything to get this working and finally stumbled across a post from someone named eclipsed, it gave three lines to insert into /etc/devfsd.conf and now it works. My card reader is USB, but it is internal so the idea of having to open up the case and unplug it everytime was not exactly useful in my case.
You'll need to change the scsi host, probably, if yours is different, which is possible.

UNREGISTER ^scsi/host1/bus0/target0/lun0/part1 CFUNCTION GLOBAL unlink sda1

Maybe it's worth a try. Like I said, after trying everything I could think of, except for long and complicated hotplug scripts (which was never necessary under any other linux OS) this worked for me. |

Thanks, but I actually don't want to automount it (this won't change anything to the problem). I first want hotplug to detect the inserted card without restarting it (hotplug).

Thanks, but I think it's easier to do an "/etc/init.d/hotplug restart" than moving my furniture to get behing my tower to unplug the reader every time...

Thanks, this creates /dev/sda1, but the scsi host is not created when the card is inserted so the sda1 link points to nothing.
I think it's a bug in hotplug. It doesn't detect the card if either hotplug or one of the modules (usb-storage, sd_mod) is not restarted with the card in; or the reader unplugged (same as restartiing hotplug)... |

| One thing that just came to mind is to make sure your kernel has the scsi option of "probe for multiple luns" enabled. Before having that option enabled only one 'part' of my reader would work. Maybe that's the case for you also, but the part of the reader that works isn't the one you need to use? On my reader with the four slots, the smart media reader is /dev/sdd and /dev/sda is for compact flash. With the probe multiple luns feature of the kernel enabled it creates four devices sda through sdd at boot. |

Thanks for the help.
Probe all luns is enabled in my kernel...  |

I have excact the same problem
a after inserting the card creates sda1, but you have to type the command manually.
Any better solution?
