Problem resolved! Required changing the MaxBufferSize StarPort parameter to 512kB (524288). Here is a revised list of values to change or confirm for StarWind 5.6 and XenServer 5.6 FP1 compatibility: StarWind server registry: (search for MaxBurstLength and change the values below in 3 different loca...

StarPort parameters were checked in the registry for both StarWind hosts and the MaxBufferSize was already set to 262144 (256kB). Here is what I've tried so far as suggested in the topics linked in this thread: StarWind server registry: (searched for MaxBurstLength and changed the values below in 3 ...

Zipped log file has been sent to support@starwindsoftware.com.

Please let me know your findings as I am anxious to resolve this.

Thank you.

I have enabled level 3 logging and after 15 minutes of testing it has created a 50MB log file. How can I upload this file to you? Do have an FTP server?

These settings have been tried after being referred to the thread you linked from this thread: http://www.starwindsoftware.com/forums/starwind-f5/mirror-feature-doesn-sync-automatically-t2376.html It is also a slightly different scenario since I'm not running HA, only Mirroring. Perhaps it should ha...

Hi Max,

What values should we use for XenServer 5.6 FP1? I'm currently experiencing the same problem with a RAID1 Mirror configuration on StarWind. Mirror goes out of sync as soon as data is written to the SAN.

I've doublechecked all XenServer and StarWind registry settings as suggested and they are correct. 1. All firewalls disabled on StarWind servers. 2. Both StarWind servers licensed and reporting the correct version. 3. I have not defined any CHAP or ACL settings anywhere. I'm at a loss as to what is ...

Hello, I've implemented the suggested fixes in the topic you referred but it seems to have had no effect. Looking at the StarWind logs, I am still seeing these relevant lines: 4/1 11:00:05.328 97c EventDB: Current timestamp is 1301626805 4/1 11:00:05.328 874 MIR: *** Mirror_SyncMirrorsOnlineWorker: ...

Hi Anatoly,

We are not running an HA license of StarWind so could this still be a problem like in the topic you mentioned? Not only that, but we are running XenServer 5.5 (something I forgot to mention) and not 5.6 or FP1.

Starwind Enterprise:

If by remote iSCSI target you mean another StarWind server on the network and not off-site, then yes it is a remote target for the second mirror.

Firewalls:
OFF

Logs:
Sending soon.

Hi Anatoly, Yes that is essentially the issue. I can be physically looking at both StarWind servers' disk drives and only see that data is being written to the first server. Only when I force a synchronization do I see the drives on the second server start blinking at the same time as the first serv...

Greetings, I have setup 2 StarWind servers for a customer and they have purchased a license that gives them mirroring capabilities. However, from what I am experiencing, the synchronization of data is not occurring unless I manually force a sync. I was under the impression that mirroring created a R...
