Exchange Comulative Update Failure

Hay,

During Exchange 2016 or Exchange 2013 server from one CU to another, you may run into strange set of errors.

Funny though, when you track those errors down you will probably end up removing OS patches and updates that actually needed and, even worse, that will not solve your issue.

I’m talkiing about tons of erros directly after the registry entries in the log file, something like:
Process execution failed with exit code 1072
and
Id=MailboxComponent___05b48d0df742416f87cbe69d27751979

Will, in my case, I had to do three things:

1. Re-confirm Schema, Forest, and Domain preparation is done using the “Setup” file from the CU I’m installing.
2. Un-install backup agent that is integrated with Exchange (in my case it was Veeam).
3. Run the setup time after time till it successfully completed. One server required (5) times, the other needed only (3).

Don’t forget to re-install the backup agent.

Exchange PowerShell Error

Well,
You start the Exchange Management Shell (EMS) after a regular Windows update, and boom, you’re end up with an error.
It says:
New-PSSession : Cannot find path ” because it does not exist
Then:
New-PSSession -ConnectionURI “$connectionUri” -ConfigurationName Micr …
And it tries all servers you’ve updated, and you end up with none functional EMS.

Ok,
1st, you shouldn’t update all servers without fully test the update on single one first, you should already know that by now.
2nd, yes it is indeed one of Microsoft products updates caused the crash of another Microsoft product.
3rd, most likely you didn’t update the product itself to the latest version.
4th, yes there is a solution, but it will cost you restarts.

So,
Check if you have the latest updates of Exchange, SharePoint, SQL, or any other application you have. And by checking I mean you check the version you have, and go to the website and find what is the latest version published and what is the latest update package (or cumulative update) is there.

If that is not an option, as I’m expecting from some Exchange and SharePoint admins, then you better start looking into each update installed on that day, and go read about it to find which one included modification and/or update of the PowerShell of the OS. You’ll need then to remove that update in order to test if the issue is gone, and if it’s not, then you’ll have to find the next update, and keep going till you find the one caused that issue.

Yes, I know it’s not much of a help.
However, you may want to check if the PowerShell 5.0 is installed on Exchange 2016 CU8 or earlier, or Exchange 2013 CU19 or earlier, then most likely you want to get back to PowerShell 4.x

Good luck,

Move WhatsApp Data to New Android Phone

Why this note?
Because I didn’t find one on the Internet addresses the gap issue.
See, the problem when you use the cloud backup you may not have enough cloud space. And more, between the moment you start the backup, until the backup is completed, you may receive several messages and medias. Which most likely will be lost once you switch to the next phone.

So, here we goes:

  1. Disconnect your Google drive from WhatsApp

Follow this article for the details: https://www.quora.com/If-I-have-both-a-Google-Drive-and-a-local-backup-of-WhatsApp-chats-how-do-I-ensure-WhatsApp-picks-up-the-local-version-to-restore-when-I-reinstall

  1. Get backup of WhatsApp folder to SD or Flash disk, and copy it to the new phone
  2. Install WhatsApp on new phone, and pay attention to the step after activation. If no backup is detected, or if it is trying to restore a cloud backup, then you missed something

Good luck :)

XG Virtual Firewall on KVM and Openstack ERROR firstboot failed

Yep, no much result on the web about this subject.

I don’t know what the cause, nor why Sophos didn’t take it seriously.

Anyway, if you’ve downloaded version 16 of Sophos XG virtual appliance for KVM and you got the nice error message of

firstboot failed: swapon /dev/swap

But, if you know and sure you’ve done everything right and as per Sophos documents, then most likely you have the same issue we run through.

For some unclear reason we were able to solve this by having the Hyper-V version of the same appliance and run it on KVM platform :)

Our team members are testing it now on OpenStack with our service provider to make sure of the compliance.

HAproxy Errors and No Logging

Basically, you’re running HAproxy 1.7.x on Debian/Ubuntu and have no logging under /var/log or you’re getting log files full of errors like:

haproxy-systemd-wrapper [26417] sendmsg logger #2 failed: Connection refused

There are many reasons for this problem, but most of the solutions are related to standard setups, which means if you have version 1.7 by the time this post is published, you’re not getting the binaries through standard apt-get libraries. Thus, you don’t have standard setup ;)

Anyway, if you’ve installed version 1.7 directly, then simply remove it, and remove pointers in apt-get libraries to its source.

Install version 1.6 from the standard libraries, and test the functionality of HAproxy, then test the functionality of the logging.

Finally, you can upgrade to version 1.7 and logs will keep working for you.

Don’t ask me why, I don’t have time to find the root cause :)
