Just a quick update on the new RC build on disk bridging. I upgraded my current build after deleting the LUNs. I rebuilt my think, thin, and SSD (disk bridge) to test the behavior against the previous build. The disk bridging killed Starwind. Hung up the RPC Server so I couldn't do much of anything with the Computer Manager. The Starwind console could not connect to the service either.
I managed to recover the situation by stopping the Starwind service, using diskpart to select the SSD, clean the SSD, then take it ofline, and finally restart the Starwind service. I'll post the original log, but will try a few more clean boots and options this weekend if possible.

AKnowles,
Could you please send us also the previous log file? StarWind service starts new log file after each restart, so I assume, all the interesting records are there.
Current file contains records starting from 3/1 18:08:27.854 .
Best regards,
Alexey.

The file is too large. Compress it is a bit over two MB. Can I e-mail it or post it elsewhere for you?

Exactly! You can compress it and drop it to me:
av@starwind.com
Please note that if the archive will be larger then 10MBs you`ll it will not pass our mail filters, so it will be better to upload it to some file hosting service (GDrive, DropBox, etc) and share the link with community or with me personally, after. Please don`t forget to put the reference to this thread if you`ll send me the email.
Thank you

AKnowles,
We have reviewed the logs. The only wrong thing in logs is error on locking the volumes of SSD storage.
When DiskBridge opens device, it tries to lock volumes that reside on this device. This is needed to exclude possibility of simultaneous access to disk volumes from server' OS and from client that have access to this disk via iSCSI. When disk volumes are in use on the server, StarWind fails to lock the disk and returns error to iSCSI initiator that connects to the target.
One thing - we have tried this in our lab and it works as expected: Initiator hangs up for several seconds and displays error. Server processes connection from Management Console and from other targets without errors.
Have you faced the same issue again after the first time? Is it easy to reproduce the issue on your server?
Best regards,
Alexey.

I haven't had a chance to try it again as I have been studying for my VCAP-DCA exam on Saturday, but I will try a few things on Sunday to see what happens.

Anton,
Just a follow up. I'm still having an issue with disk bridging. Almost the same issue as previously. I was able to create the disk bridge without taking the disk offline. But then ESXi 5.5 could not format it with the previous GPT partition. So, after taking it offline, cleaning it, then reattaching it to Starwind RC1 I could present it to ESXi 5.5, but it would not format it (different error). Even after a reboot of the ESXi hosts and the Starwind Server it could not be formatted.
I'm going to try and start with a clean slate on it and see if that work. In the meantime, here's my log from my attempts ...

I have reviewed the logs. Every write attempt ends with "The media is write-protected." error (code 19).
Could you please show also Windows Event log records? May be, there we'll find some clues to issues with locking device for read-write access.
Best regards,
Alexey.

Alex,
I will purge both teh Windows & Starwind logs, reboot, and try and replicate the event and provide both sets of logs to you.
Thnaks,
Art

Just an update. I used the latest build and can once again create a disk bridge. But it only worked when I cleaned the disk (removed all partitions) and left the disk online. In prior builds it needed to be offline. I'm not sure if this is a quirk of Windows Server 2012 R2 or not. I'll see if I can do a bit more testing on the weekend, but I was happy to just be able to mount it once again.

Various "issues" like this is one of the reasons say MSFT had ripped this functionality off their target...
