I upgraded our ESXi and vSphere Center to 5.5 update 3 last week before seeing this, but have not had any trouble so far. We run everything across iSCSI and all virtual machines are stored within the root folder of each iSCSI target folder. We also don't have Enable VMware Tools quiescence turned on either. This thread suggests trying to turn quiescence off and see if that helps. We've never had that turned on, so maybe that's why we haven't experienced any issues. https://communities.vmware.com/thread/5 ... 0&tstart=0

I was told we'd see a patch this week actually.

I'm still running Veeam with ESXi 5.5 U3, and I have not seen the issue so far thankfully. But I do agree with Gostev's comments on his weekly digest that VMware's QA recently has been awful.

I'm guessing the snapshot issue is caused by something in patch ESXi550-201509201-UG. The OpenSLP Remote Code Execution security issue is fixed in patch ESXi550-201509101-SG. I would assume the security patch can be applied separately, thus avoiding the snapshot issue. Can anyone confirm this?

Well spotted. I wonder what other issues this patch introduces? ;(

Installed it late last night on our internal infrastructure and reenabled all our backups.

No issues to report.

Likewise, I upgraded from U3 last night too, and no issues so far.

I'm here to report, I have updated vCenter 5.5u3 and updated my hosts to ESXi 5.5 u3a.

I didn't make any changes to my jobs, moved one VM into the new host, test a backup job.. worked as usual.

So far so good.

So is ESXi 5.5 U3a safe to upgrade to now? We've been avoiding v6 due to the constant critical bugs that are found every week :(

ESXi 5.5 U3a should be safe, yes. I didn't heard any issues about yet. However, I'm still running ESXi 5.5 U3 (without the patched snapshot bug) and even this is still running fine in my lab.

And: Still avoiding ESXi 6.0 may be an good idea, because: http://kb.vmware.com/selfservice/micros ... Id=2136854. This should also affect Veeam - as far as I know Veeam is also using CBT (Changed Block Tracking).

Yes, Veeam B&R uses CBT and there's a dedicated thread regarding this issue.

Yeah, I saw that in the forum digest email - Thanks Gostev!

I guess I'll give 5.5 U3a a go then, thanks for the info :)
