 Posted: Fri Oct 14, 2005 4:51 pm Post subject: no /dev/sd* when connecting firewire drive[SOLVED!] |
 |
|
EDIT: in my case, the inability format or mount the firewire drive was due to the kernel not recognizing the partition format. Because I am running PPC, the PC BIOS partition table support was turned off by default (AFAIK). Enabling it fixed the problem.
/EDIT
Howdy,
the kernel sees my firewire drive when it gets plugged in, and creates a SCSI ID for it, but I cannot get it to create a /dev/sd* node.

All the firewire options are enabled (but not as modules) in my kernel. Is this a Udev permissions kind of thing? The disk on the firewire interface is unformatted, but that shouldn't make a diff whether or not the /dev/sd* node gets made correctly.

I just answered the same thing in another thread so I hope it's right 
I had the same problem with a USB memory stick - it wouldn't create the /dev/sd* entry until I modprobed sd_mod which was part of the scsi kernel options |

OK, I double-checked my kernl conf and found that actually I had no SCSI support enabled, so that's taken care of now. But I still have some troubles.
I can fdisk /dev/sda and create /dev/sda1, but I cannot format or mount it:

And what's more I don't have sd_mod (at least not as a module). Further suggestions? Would anybody like to see a kernel conf?

But which error(s) do you have trying to format it ?

It's controlled by the CONFIG_BLK_DEV_SD parameter. You will only have the sd_mod module if your SCSI support is built as module. In your case, it seems you have it built-in, so you don't need the module. |

Here's the fdisk output, showing a partition at /dev/sda1:
| Code: | # fdisk /dev/sda
The number of cylinders for this disk is set to 16709.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)
Command (m for help): p
Disk /dev/sda: 137.4 GB, 137438952960 bytes
255 heads, 63 sectors/track, 16709 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sda1 1 16709 134215011 83 Linux
|
And here's the mkreiserfs output, showing no partition at /dev/sda1:
| Code: | # mkreiserfs /dev/sda1
mkreiserfs 3.6.19 (2003 www.namesys.com)
Failed to open '/dev/sda1': No such device or address.

Now you see it, now you don't! Nice trick, huh?
Udev shows this:

Something of a BUMP. I've done a lot of kernel mucking since I started this thread, but I still have the same old problem. I can't get my firewire drive attached to /dev/sda1.
Dmesg reports this:
| Code: | ieee1394: Node resumed: ID:BUS[0-00:1023] GUID[00d04b281308c1ce]

Fdisk can find the drive and see the partition, but mount can't find it:

mount: you must specify the filesystem type
macumbista derek # mount -t ext2 /dev/sda /mnt/firewire/

or too many mounted file systems
macumbista derek # mount -t reiserfs /dev/sda /mnt/firewire/
mount: wrong fs type, bad option, bad superblock on /dev/sda,
or too many mounted file systems
macumbista derek # mount /dev/sda1 /mnt/firewire/
mount: special device /dev/sda1 does not exist
|
I really don't know where to keep looking at this point. Should I blame Udev, or should I blame something in the kernel? I've tried to mount both a USB and a firewire exsternal drive with several different disks and different file systems, all with no luck.
The weirdest thing is that my Ipod mounts fine!

The main error seesm to be an inability to read the partition table of the USB or Firewire HD. But why does the Ipod work, then?
Help! |

Do you, by any chance, have this option turned off in your kernel ?
| Code: | File systems --->
Partition Types --->
[*] Advanced partition selection
[*] PC BIOS (MSDOS partition tables) support |
BTW, the ipod works because it is using a mac partition map. |
