[XPEnology DS3612xs DSM 4.3 build 3810++ (repack v1.0)]

Just made a clean install of v1.0 on my test computer (ASUS P5KPL-AM SE, Q8200, 4GB, 160GB 2.5", Intel PRO1000 PT Server) to test iSCSI.

After setup, I can create lun/target without error in DSM (few errors in the console about failed to mount boot device /dev/synoboot2/, I will try to fake it in the future).

I can connect it with my Win7 Pro computer, reboot XPEnology, windows autoreconnect iscsi drive and vis-versa, read/write are about 90-100MB/s

 

iSCSI works fine in lio mode after dsm setup without modifying anything. If someone can confirm on other hardware.

 

BUT iSCSI support is broken in betas (too many things added, like virtualization, xen, kvm...), and I can't successfully build working iscsi modules

I decide to restart from scratch with v1.0 config, and add things step by step to not break the iSCSI support.

 

 

I notice with the new beta v1.4, that CPU temps seem to be stuck at 40c

Normal Repack v1.0 temps change and read (I hope) properly

 

With my ASUS P5KPL-AM SE temp is alway (with v1.0 and beta v4) stuck at 40c...

 

confirm working with a clean config.

Modifying DSM 4.3 synobios.ko in Linux.

 

1. View the source code and look for the second 'ba ff ff ff ff' (25e1) in SetMicropId function using objdump.

 

# objdump -S synobios.ko | less

orig:
   25da:       e8 00 00 00 00          callq  25df 
   25df:       85 c0                   test   %eax,%eax
   25e1:       ba ff ff ff ff          mov    $0xffffffff,%edx
   25e6:       75 c4                   jne    25ac 
   25e8:       0f be 04 24             movsbl (%rsp),%eax
   25ec:       31 d2                   xor    %edx,%edx
   25ee:       89 05 00 00 00 00       mov    %eax,0x0(%rip)        # 25f4 

 

2. Replace the next entry (25e6), change it from '75 c4 0f be 04 24' to '48 31 c0 b0 42 90' using xxd.

 

# xxd -g 1 synobios.ko > synobios.hex
# sed -i 's/75 c4 0f be 04 24/48 31 c0 b0 42 90/' synobios.hex 
# xxd -r synobios.hex > synobios-edited.ko
# objdump -S synobios-edited.ko | less

   25eb:       90                      nop
   25ec:       31 d2                   xor    %edx,%edx
   25ee:       89 05 00 00 00 00       mov    %eax,0x0(%rip)        # 25f4 

 

3. To disable the logging message, find '80 7c 24 17 00' (395) and replace the next entry (39a) with 'eb d4' in synobios_poll function.

 

# objdump -S synobios.ko | less

orig:
    394:       c3                      retq
    395:       80 7c 24 17 00          cmpb   $0x0,0x17(%rsp)
    39a:       74 d4                   je     370 
    39c:       be 24 02 00 00          mov    $0x224,%esi

 

# sed -i 's/80 7c 24 17 00 74 d4/80 7c 24 17 00 eb d4/' synobios.hex
# xxd -r synobios.hex > synobios-edited.ko
# objdump -S synobios-edited.ko | less

The new iSCSI (LIO) currently is not enabled with Trantor's kernel build, but there's still a problem even if its enabled which I'm trying to figure out. To make iSCSI work, you have to change iscsi target type to IET in synoinfo.conf.
