Two problem with esxi 6.7 - dsm 6.1

Hi , 

I have setup a dsm 6.1.7 on esxi 6.7.

The setup is:

- jun loader 1.02b vmware boot option

- loader boot disk is alone on first sata port

- unique data disk is on paravirtualized scsi controller

- network is vmxnet3 10gb

 

I've install all 6.1.7 updates , only packages installed are stock file station , universal search and open-vm-tools.

 

The system will be a test environment for a spk package development so I don't need special package but need high i/o speed because my app move a lot of data.

 

Using 10GBe as network and ssd as vmfs storage I get all performance I want.

 

Now I'm testing the setup before starting to use it , doing that I found two problem:

 

First , inspecting logs I see that /var/log/messages has a lot of:

2018-07-05T15:39:57+02:00 syn synostoraged: SmartDataRead(108) read value /dev/sda fail
2018-07-05T15:39:57+02:00 syn synostoraged: disk/disk_temperature_get.c:99 read value /dev/sda fail
This is repeat every minute and the log file continue to grow...

Now , I know that smart is not available in a vmware virtual machine but i would like to know if there's a way to disable smart check and continue error logging.

 

Second , I've try to enable jumbo frame in the vm to maximize network performance , the virtual switch and the phisical one have both jumbo frame enable ( mtu 9000 ) and so is the client used for test.

I've found a strange problem , when I use vmxnet3 ( only way to get 10gb without assign a direct nic to vm ) i can't raise mtu more than 3050 , I don't know why exactly 3050 , but if I set mtu to 3051 I get a kernel crash and the dsm hangs.

This is the same raising mtu on command line or from dsm interface ( if someone would like to test the best way is use command line because a reboot solve the problem ).

Using e1000e virtual adapter in place of vmxnet3 solve the problem and let me use a mtu of 9000 but obviously I get only 1GB connection.

 

Is there some place where to see the source of the compiled modules contained in the loader or there's a way to report a bug to who maintain it ?

I had a similar problem, only way I could get things to work when ANY NIC had jumbo frames was to use E1000.  I pass through my 10GBe card to DSM finally, and that works but I don't have other VM's that need high bandwidth.
