Unable to remove Office 365 Domain

With Cloud on the �loose�, Microsoft has offered a very flexible platform which allows organizations to easily subscribe for trials or even register for a tenant on the fly. However, without a proper clean-up would create additional hassles and steps, especially if the Global Admin is no longer around or the login credential has been misplace � and this what happened to me in a recent Office 365 engagement.

In this implementation, we were supposed to activate the actual domain (Example: mydomain.com) to a new Ofifce 365 tenant. However, when attempting to associate the corporate domain into the Office 365 tenant, the portal had detected that our domain has been used and activated with another tenant � for Microsoft Power BI purposes, to make things complicated, nobody knows whom own the other domain.

To �regain control� of the corporate domain, we�d to create an automated generated TXT record to proof that we�re the actual and will be the Global Admin taking over the Power BI tenant. After which we�d to remove the corporate domain that has been configured with the Power BI tenant but were thrown with an error message:

Dependencies on domain. To remove this domain, you�ll have to remove the following dependencies first.

When expand, the alias and Skype addresses indicate the users which has been assigned within the tenant, although there wasn�t any Exchange Online and Skype for Business Online licenses are available. In the end, we�d to use PowerShell to remove the corporate domain:

• Connect-MsolService
• Remove-MsolDomain -DomainName $mydomain.com -Force

Refresh the Admin portal and we manage to remove the corporate domain that was initially assigned to the Power BI tenant and �migrated� it to the actual Office 365 domain.

Proxy:  
202.152.156.210

Port: 8080

Search for a proxy in �Indonesia� with Port no. �8080? as shown below

2. Save Settings

 

Note: Open your facebook account before changing proxy, if your account is not opening after changing it.

3. Now its time to open your Facebook Account and Go to Account Settings.

4. Change your Language to Bahasa Indonesia.

5. Then simply remove your last name then Save it.
6. Switch back to English(US) language.
After doing all step remove proxy & switch to system proxy.
Now you have only single name account you can amaze your friends by this trick.

Must share and Enjoy....

Note: Im not much pretty sure but since were not allow to use only single name fb account, there is chance to get blocked for some facebook features. But you can tryat once.

Ubuntu 12 04 Remove Physical Drive From Volume Group

In this tutorial I am going to show you how to remove a drive from your logical volume group without losing any files by first moving all of its contents onto the other drives. This means that you do not have to take a full backup to another set of drives. I did this today because I wanted to replace a laptop drive that I had temporarily added as emergency "extension". Using the drive had noticeably decreased the performance of my volume group when writing new files and reading from those files later on.

The first step is to look at your physical volumes in your volume group. You should have already added your new drive to the volume group if you are performing a replacement. This will also work if you have enough storage remaining on the already existing drives.
sudo pvs -o+pv_used


Hopefully that shows you that you have enough space on your other drives. To spread the files from the drive you want to remove, just enter the following command:
sudo pvmove /dev/sd[x]


This takes a long time. So at this point it is probably best to go away and watch a movie.
When that has completed, you may want to run the following command again to see how everything is spread.
sudo pvs -o+pv_used


You can now remove the drive from the volume group with the following command:
sudo vgreduce [volume group name] /dev/sd[x]
For example:
sudo vgreduce vg_main /dev/sdb
Thats it! You can now physically remove the drive from your machine. If you run step 1 again, you will see that it no longer appears in the volume group as shown below:
