Dual CPU Server - Wrong CPU Core 4?


Recommended Posts

i have installed the dsm 4.3 1.1 beta 5 on an intel board with 2 cpus. at the console i get an error "wrong cpu core: 4". How can i fix this?

 

I get the same message every minute or so on an HP DL180G6. It's a dual slot motherboard, but I'm running only a single CPU with four cores. It appears to cause no problems, but it is annoying.

I have a TYAN bi-cpu motherboard with one Opteron 6174 12cores on it. I will try on it.

 

I will increase CONFIG_NR_CPUS value too.

 

Is this something that may be fixed in a future update from you Trantor? That would be fantastic if Yes. I’m on 5.0 beta, by the way. Loving it!

Just tried with my Opteron 6174. No error in console.

CPU cores in System Information show 8 (instead of 12 but CONFIG_NR_CPUS is set to 8 in kernel so this is normal).

 

I will build a testing kernel with CONFIG_NR_CPUS=16.

 

Can you give me the output of:

 

# dmesg | grep CPU

and

# dmesg | grep SMP

I tried it already, doesn't work. MAX CPU config is working but it breaks LIO iSCSI:(

 

:sad:

Thank for the tips ^^

I'm curious of the output of the 2 commands I post above on system with this issue. Maybe it will help us to find out the "source" of this bug.
