In absence of hotadd or proxyVMs, will this regression issue affect us?
Yes. The only thing that seems to matters is your host load.

Just noticed VMware have released a new patch ESXi-6.5.0-20181004002-standard (Build 10390116) which includes the following in the release notes ..

PR 2209189: Heavy I/Os issued to a snapshot virtual machine using the SEsparse format might cause guest OS file system inconsistencies
Heavy I/Os issued to a snapshot virtual machine using the SEsparse format might cause guest OS file system inconsistencies, or data inconsistencies in applications.

Is this the esxi side fix for the regression ?

No, it's a different regression that VMware has first disclosed just last week - we were not aware of it.

To the folks who mentioned use network mode over hot add - I would have to better understand if there is a performance hit doing so considering the size of our environment and the number of jobs I have running. I would expect proxy hot add to be the most efficient way to complete the backups.
@rmyers - I have a very similar environment. I bit the bullet last week and switched all my Veeam proxies to Network Mode only. I was pretty nervous doing this given the size of my environment, but all has been well the past 7 days. I did notice a decrease in performance though as anticipated so expect that your backup window might go a bit longer.

The following issue listed below just started to affect our environment. I see some response in the Veeam forums about a possible VMware patch being released by the end of November to address this issue. We've opened a case with VMware support and Veeam support but haven't gotten a concrete answer of when a patch will be released to address this issue. Any updates?

This looks to be a different 6.5 U2 issue from the "main" one that have been discussed in this thread so far. We have not been in contact with VMware on this one, so I don't know much about it at the moment. Except that it is certainly not a common issue in our support.

Hi guys,

Have you got any updates on this?
Do you have any figures on how many customers that have 6.5U2 are experiencing problems?
We are running metro cluster setup, so our hosts are never loaded to more than 50%, so if this is triggered by high load perhaps we could be safe?

Hi - yes, you should be safe with your load. In general, I don't believe we have had many customers report being impacted by the issue. I think this is because when the issue does happen, automated retries just take care of it transparently. Thanks!

Hi again, and thanks for the prompt reply!

VMware seems to have released a new version of vCenter recently (well, yesterday);
https://docs.vmware.com/en/VMware-vSphe ... notes.html
There's also a new patched version of ESXi released:
https://docs.vmware.com/en/VMware-vSphe ... 11002.html

Seems like a couple of issues are fixed, not sure if they are affecting Veeam or not tho..

Could someone from Veeam please comment on this most recent VMWARE patch.
The changelog really reads as if the load issue has finally been taken care of.

Thanks,
Mike

Mermaid, the question was about the Heavy Load issue in overprovisioned environments in U2, not the hotadd issue.

[MERGED] Veeam 9.5 Udpate 3a and vSphere 6.5 Update 2

Post by falkob » Dec 14, 2018 8:30 am

Hi community,

i have customer who wants to upgrade his vSphere Infrastructure to vSphere 6.5 Update 2.
He is concerned about the "Known Issues" described in this article: https://www.veeam.com/kb2443

There are two Known Issues with VBR 9.5U3a and vSphere 6.5 Update 2

1. Supported with the exception of issues caused by a regression introduced in ESXi 6.5 U2 that causes its API to fail randomly under heavy host load.
2. There is a known issue where a Veeam Proxy running on a VM may become listed as (invalid) in vSphere. More information here: https://kb.vmware.com/s/article/56453


Issue number 2 won't have an impact on my customer, cause he is using physical Proxies with Direct Storage Access.

But in fact i wanted to know about Issue number 1. How frequent does this "occur" ? Are there any experiences on this ? What does heavy host load mean in this context ?

Thank you so far !

Best Regards

Falko
