3ware 3dmd & 2.4.12-ac: Error: No Controllers Found

3ware 3dmd & 2.4.12-ac: Error: No Controllers Found

[Jurgen Botz]

The latest 3dmd from the 3ware site doesn't seem to work on recent
kernels, at least on 2.4.12-ac{2,6}.  The driver/array work fine.
3dmd starts up, but bringing up the page gives:

  Error: No Controllers Found

I get the following in syslog:

  Oct 23 09:28:35 nova 3dmd: ioctl(4) failed: No such file or directory
  Oct 23 09:28:35 nova 3dm: 3dmd startup succeeded

Doing an strace on 3dmd (which succeeds only partly, due to threads?)
yields the following, which may be related:

  1649  open("/dev/sda", O_RDWR)          = 4
  1649  ioctl(4, FIBMAP, 0xbffff2a0)      = 327680
  1649  fstat64(1, {st_mode=S_IFCHR|0620, st_rdev=makedev(136, 2), ...}) = 0
  1649  old_mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, 
-1,
        0) = 0x40000000
  1649  ioctl(1, TCGETS, {B38400 opost isig icanon echo ...}) = 0
  1649  write(1, "ioctl(4) failed: No such file or"..., 43) = 43
  1649  close(4)                          = 0

Anyone else run into this?  Any ideas on how to fix?

I just checked and found I'm having the same problem.  I'm at
2.4.12-ac5 plus LVM 1.0.1_rc4.  I have no idea what could be going on;
I've been lost a couple of times in the 3ware driver without
understanding much of what's going on in there.

The problem is still there in 2.4.13-ac5 and 2.4.13-ac7, with the same
symptom:

Nov  3 15:46:27 bertha 3dmd: ioctl(4) failed: No such device or address
Nov  3 15:46:27 bertha 3dm: 3dmd startup succeeded 

Although the web interface to 3dmd doesn't appear to find the controller,
everything else appears to work just fine.

Plain 2.4.13 (and earlier, at least 2.4.10 and 2.4.12) appear to be OK.

I'm running the 7.3.2 release of the firmware (7.3.2 FE7X 1.03.09.027) and
3dmd (1.10.00.020), and using the driver included with the kernel
releases. Interesting features: Escalade 7810 with 8 drives, dual processor
Athlon MP on a Tyan Tiger mb, Netgear GA620.
