Latest stable build(s)?

I am looking to update our production system and wanted to find some information regarding the latest builds.

I am running build 7145, all thick images, LSFS turned off due to LSFS growth bugs. It took about 5 to 6 revisions to fix this issue (over 6 months at least) and therefore we have never updated this production system. It is VERY stable as compared to almost all other v8 installations/builds I have worked with. The one issue is that a restart of the StarWind service that requires a hard-shutdown of the process will 100% of the time result in full synchronizations. This is a known quantity and so we can live with this.

But now I just encountered the Endless-Loop-Synchronizing issue on a 200GB image. It never gets to 100% and restarts about every 5 minutes. StarWind says that this was a known issue in build 7145 (not that I've ever seen or heard of.. sure other versions, but not 7145) with cache issues. I am waiting for information from support on whether the server logs show if this is a cache issue or an issue with high workload. This is a swap/scratch image for one of the VMWare hosts; so high workload I could see; but I don't want to migrate a bunch of VMs on a whim. So I wait to see if we can suss out what is going on within the log files. (Ticket 17641 in case any support people read this post and want to look into it.)

So now I've moved the upgrade of StarWind toward the top of my priority list. The build I have at the office in the lab is build 7852. It is also very stable. It does NOT exist on the webpage for latest versions/release notes. Was this version retracted? If this build was not retracted, where are the release notes and the download for this version?

Can anyone chime in on stability of the latest builds: 8198 (June 11, 2015), 7929 (April 17, 2015) or build 7774 (February 26, 2015)? I've looked through the forums and haven't found anything that was not related to LSFS stability fixes until 8198 where they state they have resolved cache performance issues. I am not (knowingly) having cache performance issues; as I receive very close if not the full 6Gbps on the SAS channel.

Basically since 7145 runs so great (excepting this endless loop I have just encountered) I want to be sure that the upgrade version I choose also is stable.

Hi thefinkster.

I would recommend you to try 7929. Still have it in production, testing the latest one 8198.

7929 does its job well

the latest, of course

So far (one weekend) build 8198 seems stable. No performance lost and probably a tiny bit gained (we don't use LSFS so wouldn't have noticed any differences there).

Oh, it's brilliant. Glad to hear that.

One of my clusters is on the latest, and another is on the previous build - Both are stable for me.

I'm not using LSFS or L2 cache

All my HA luns are in WT instead of WB mode (waiting a few months before switching back to WB as I had noticed major slowdowns in resync when using WB)

Cheers
