[Firewire-users] Trouble with 2 concurrent logins

[Diane Petersen]

Help!

I can't seem get both nodes to access the shared external storage drive
at the same time. I'm using the following configuration:

2 AMD Sempron 2200 (1.6ghz) pcs each with:
1GB RAM, 2-NIC's, 1-ieee1394 VIA controller firewire card
External HDD: Maxtor One Touch 200GB w/Firewire & USB 
(2-6pin ieee1394 connectors in the back attached to each node)
Fedora Core 3 - 2.6.9-5.0.3.EL.orafw1 kernel patched from:
http://oss.oracle.com/projects/firewire/files/RedHat/RHEL4/ to allow
simultaneous access.

But my disk is only detected by one node at a time. Since FC-3 no
longer has a /etc/modules.conf file, I added the following to
/etc/modprobe.conf: options sbp2 exclusive_login=0

-Didn't make any difference...

Output on node 2 from dmesg | grep sbp2
ieee1394: sbp2: Maximum concurrent logins supported: 3
ieee1394: sbp2: Number of active logins: 1
ieee1394: sbp2: Error logging into SBP-2 device - login failed
sbp2: probe of 0010b9f700afca21-1 failed with error -16

Node 1 has access to the external drive:
[root at red ~]# fdisk -l /dev/sda
Disk /dev/sda: 203.9 GB, 203927060480 bytes
255 heads, 63 sectors/track, 24792 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1               1          37      297171   83  Linux
/dev/sda2              38        6117    48837600   83  Linux
/dev/sda3            6118       12197    48837600   83  Linux
/dev/sda4           12198       18277    48837600   83  Linux

-More accurately, whichever node boots first or remains active last,
has exclusive access to the drive. What am I missing?

Does anyone have a configuration working with RHEL4 or Fedora Core 3? I
followed all of Jeffrey Hunter's instructions to "Build Your Own Oracle
RAC 10G Cluster on Linux and Firewire". I even tried the White Box WBEL
2.4 version first and the applicable 2.4 patch from oss.oracle.com but
didn't have any luck with it either, basically same results...

Please help! Thanks in advance!
Diane
