OK, and can you please check the CPU and RAM load on the SAN server while you are trying to connect to target with more then 1 ESX and it hangs? Usually it was 20-30% cpu usage (under active load) and between 2-4GB RAM usage depending on how I had the target devices set up. There was no apparent co...

I put a huge amount of load on it tonight over 3 active paths and none of the paths died so I suspect yesterdays issue was an isolated one.

Do you have any particular idea as to why I need to have caching active to prevent the dedupe devices from freezing?

Is that what you are after?

Another oddity, when i turn on round robin mpio I will see the second path become active and send traffic for a short interval (about 10 minutes), then I get the error below, then the second path becomes idle even though the overall storage operation continues (using storage vmotion to generate traf...

Very interesting, your previous question prompted me to put a cache on the dedupe device.. it is current processing about 500mb/s of IO from two hosts and isnt freezing..

Windows Server 2008 R2 Standard - SP1 only, no other patches.
Physical devices are 120GB SSDs. Starwind devices are 110GB.
No caching on any devices.
8GB total on the SAN box.
I have tried auto and 256k. Same result.

So I removed I removed one of the basic devices and added a dedupe device. Same result as previous. Target froze, VMs go unresponsive. I have sent the logs through to the support email. Sigh. I dunno if it would make much difference, but the physical underlying devices I'm using are SSDs, that would...

Looking good so far using non dedupe devices.... They've only been clustered for about 20 minutes though..

Any thoughts on what might be causing it>?

Did some more testing to rule out issues caused by hardware/network layers. Rebuilt the starwind box from scratch.. Repeating the test with XenServer6 as the host, same result, only difference was that there were no errors in the starwind log file this time. VMs still froze when both hosts started t...

Yes

It happens multiple times in that timeframe.

I just grabbed the entire log folder sorry.

Just looking through the logs:
5/8 21:38:17
5/8 9:10:52
5/7 22:41:42
5/7 21:15:40
5/2 20:27:05
5/2 20:36:10
5/2 19:04:58

Thankyou

Done that.. guess I just play the waiting game with support now

Hi, OK, we have some question: -what StarWind build and version are you using? -what target typer are you using (Image File, CDP, DD, etc.)? -have you created multi-LUN target (one target with different devices) -how exactly targets are used (what for? what is storing on them)? -can we see your net...

Hi, I have been trying to set up a small home lab using the free version of the Starwind iSCSI target and have run into a strange issue. The target will become unresponsive whenever more than one ESXi host is connected and some load is placed on it from both hosts. It will stay responsive and perfor...
