 Posted: Fri May 31, 2002 8:39 am Post subject: /dev/sda and /dev/sda4 oddity |
 |
|
When trying to mount my Zip drive (built for modular support through sd_mod) I get the error that sda4 is not a valid block device, but if I try to mount /dev/sda first this seems to create the /dev/sda4 entry thus allowing me to use my drive. I'm just curious what would be causing this, and if there is a way to 'fix' it. TIA.

what do you have in /etc/fstab?
/dev/sda4 /mnt/zip100.0 auto noauto,rw,user 0 0
I have a scsi zip but the entry for all zips is the same. A friend of mine has a usb zip and his fstab entry is the same as mine listed above.

| I have the same prob with usb-zip100. If I insert a zip in the drive and modprobe usb-storage /dev/sda4 appears and I can mount it. After ejecting the zip, /dev/sda4 disappears again. I guess it has something to do with devfs but is there any way to have a permanent sda4 ? |

I have a parallel port zip, and I just modprobe ppa and then mount /dev/sda4, and it works.
Something funky in your devfs.conf perhaps?

I also have a parallel port zip, what settings should I specify in my kernel config? I have parport.o as a module, is that enough?
TIA |

I don't have one, but look in kernel tree (/usr/src/linux) in make menuconfig | Quote: | | SCSI SUPPORT -> SCSI-DISK support |
. the help states that you need it for parallel zip-drive. The module is called sd_mod.o. (mentioned in the first post)
But maybe you need more....

Make sure that you compile VFat support into your kernel. That one drove me nuts to get working right. But once it did voila, a working zip drive.

Alright I'll build that module. What about ppa, someone mentioned this here.. Do I need that module as well? |

Yes probably depending on your zip drive (old/new) you have to choose between ppa / imm module (check the help)

Think that's it, Cya lX

Like stated above, my system would generate a sda4 after I tried to mount sda, but I didn't like doing that (kinda beat the point of using supermount) so I added this to my /etc/devfsd.conf:
| Code: |
# Create /dev/sda4 for the Zip250 drive
LOOKUP ^sda4 CFUNCTION GLOBAL mksymlink scsi/host0/bus0/target0/lun0/part4 sda4
REGISTER ^scsi/host0/bus0/target0/lun0/part4 CFUNCTION GLOBAL mksymlink $devname sda4
UNREGISTER ^scsi/host0/bus0/target0/lun0/part4 CFUNCTION GLOBAL unlink sda4
|
You may need to chane the device (scsi/host0/bus0/target0/lun0/part4) depending on your setup. This works for me so I stick with it. However, my kernel bitches with an I/O error because of sda. This happened even before I added the aforementioned lines to my devfsd.conf though. Like I said though, it works so I just let it bitch.
