[Samuel Maftoul]

Hello everyone,
        Still me with my ieee1394 problems :)

Workaround: My goal is to make ieee1394 HardDisk  work in a production 
environment:
	User come on a machine, plug his disk, store his (experience 
	results) datas on it, unplugs it and go away with it in his home
	institute where he processes his datas.


Tests:
Boot with no devices plugged, no modules related to ieee1394 loaded
-load module ieee1394
-load module ohci1394
	gives a kernel warning: Get PHY Reg Timeout
keventd is up and running

plug of the HD gives in syslog kern.debug:
------------------------------------------------------

replug of the HD
Gives quite the same message as above on plug and unplug


Reboot of the machine with the disk plugged in.
(Maybe reboot isn't needed)  
Modules are loaded manually. 

load of modules ieee1394, ohci1394
module ieee1394 doesn't give any message.
module ohci1394 gives a lot of message (in kern.debug), discuss with the
HD plugged in, gives info about it (30GB ..), loads the sbp2 module.
Here is what i have in kern.warn

Now lets go for the unplug of the last plugged HD:

The unplug of the only working disk gives no message in kern.warn
The replug gives:
Nov 28 08:52:05 test17-248 kernel: ohci1394_0: SelfID received outside of bus reset sequence
Nov 28 08:52:10 test17-248 kernel: ieee1394: sbp2: Node 0:1023: Max speed [S400] - Max payload [0x09/2048]

Comments:
It seems that the hotplug is working only if the device is plugged before
the boot of the machine or loading the modules (just tested, don't need
to boot the machine with the devies plugged, just need to have plugged
the device before loading ohci1394 module).
This is not really hotplug, right ? Is this normal ?
The is really annoying because if I automatically load the module at boot
time, we need to have a device plugged on every machines what is really
not handy.
The other issue is that the only first device plugged is working.
This isn't really a problem because I need just 1 disk to be plugged but
is this normal (I think so)?

You should update to the latest cvs version, as it has some fixes for
sbp2 plug/unplug issues that hasn't yet made it into 2.4.  Move your
drivers/ieee1394 directory out of the way and then checkout the cvs
drivers as described here:

        http://linux1394.sourceforge.net/cvs.html

I don't see any mention of the kernel version you are using, nor about
the specific ohci chipset, or the hardware (ppc, i386?).

Give me some details. I don't see this issue right now, but I'm using
linux1394 CVS.

i386, AFW-4300, 2.4.16, ieee1394 from kernel (not CVS , but soon CVS :)
)
Most problems resolved.
Now I'm working on a script to automount and autoumount the HD.
This is so fucking hard 'cause we are not aware of what user wants to
use the disk (for mount -o user to let the user accessing his datas in
rw mode). Another problem is the umount: if the directory s busy, my
script isn't able to du "cd .." for the user ...
so crazy

Ieee1394

[Samuel Maftoul]

I have an AFW-4300 card, Lacie pocket hard drive.
I compiled a fresh 2.4.16 (which works perfect :-) ).
I installed the latest modutils version I found at kernel.org (rpm -Uvh
--force --nodeps (nodeps because it won't install because of a tiny kde
app called ksysguard and I don't need it.)
I have also the hotplug package installed and he ieee1394.agent file.

First, I want to report a crash:

I hope here is enough, and if you need more, I can send a lot more.
It happened while plugging Hard drives (I plugged 1, the second, and at
the third one, it crashed).
ieee1394 , ohci1394 and sbp2 modules were loaded.
I have the "Excessive debugging output" option enabled.

The second problem I have is:
I don't really understand what for is the hotplug ? can It automatically
mount any new firewire disk I plugged ? How should I do it?
Does someone have a sample script which does  something like:
fdisk -l /dev/$justplugged | awk ... | grep ... ; for i in
$mountabledevices ; do mkdir /mnt/$cnt ; mount ... ; done 
( I hope you got what I'm searching for.)

        Thanks for any help.

???? modutils does not need nor provide ksysguard.

The linux-hotplug package doesn't directly allow you to do automatic
mounts of filesystems that are plugged in, but it could :)

Right now it's focusing on automatically loading the proper kernel
driver for any device that has been plugged in.  See the
http://linux-hotplug.sf.net/ site for more docs on it.
