system stops responding

Hi Guys,

I have been using open-e for the last 2 months now connected to an HP BL460C G1 Blade server on which there is ESXi installed hosting 4 VM’s. Today one of our developers told me that he could not connect to his development VM. When I opened the VI client and connected to the ESXi host I could not open a console to the VM and ESXi replied “Cannot locate vmx config file”

I tried to connect to the open-e box through the web interface but the page could not be displayed. The open-e machine was pingable but I could not connect to it. I had to turn off the machine forcibly (kept the power switch pushed for 4 seconds) and then when I restarted I had about 23 error messages in the event viewer of the open-e box.

How can I further diagnose the issue. Is there a way how I can upload the log file so that anyone may help. The machine on which I am running open-e is an HP PC with 512MB of RAM Intel Pentium 4 3.0Ghz CPU and 2X 1TB SATA HDD configured in a RAID-1 through a software RAID with open-e.

I am also using the 2TB DSS V6 Lite license..

What did the error messages say??

You should be able to download the logs from STATUS -> HARDWARE -> Logs
check dmesg and critical error.log

also try sending the logs to support

Hi symm,

thanks for your reply. The event log seems to have cleared the messages. Below find the ouput of the critical error.log:

I think that the error is quite obvious:

2009/10/28 03:00:07|[<ffffffff80273556>] out_of_memory+0x1b6/0x230

The machine only has 512 MB of RAM and upgrading that needs to be my top priority. Do you think that the error though is according to my assumption (RAM).

Also I already sent the issue to support and support replied that since I am not a paying customer (DSS V6 Lite) I would need to refer to the forums for support

Thanks

Luke

I'm suprised you got as far as you did with 512mb of ram.
I tried dss lite v5 with 512mb a while back and it did not let me boot

I would use at least 2GB of RAM, (it's cheap these days)
If your using file I/O it will use the ram for cache


Minimum Hardware Requirements:
x86 - compatible PC
1 GByte RAM
CPU (1 GHz or faster are recommended)
HDD (SATA, SAS, SCSI, ATA) / iSCSI Storage
Network Interface Card

Hi symm,

Thanks for the info. As you may imagine this is a test system and thought to try it out with just 512MB of RAM. Already purchased 2GB though as you suggested.

Thanks for your help.
