Installing and upgrading help

Hey, Syed!  (uhhh, know something about the entity) ...

Was waiting to reply to see if any of the known Azure users in these forums would respond, but haven't seen any 'traffic' from those persons in a while.

So ... IF am understanding the question correctly ... you have RHEL (commercial) in an Azure environment already and now need more space on the RHEL guest OS ... that correct?

Could be wrong ... am sure someone will correct me ... but ... think most Virtualization platforms (Azure, VMWare, Virtualbox, Google, possibly even Amazon) can allocate more memory easily enough to the guest OS's. 

Space however, different story.   Easy to do in the Virtualization host but the guest OS doesn't recognize the space automagically ... one has to 'grow' the partitioning in RHEL.   That's NOT fun at all.

Me thinks better approach would be to create a data device in the Azure with whatever size needed, then in the Guest OS mount the data device.  Mount could be made permanent but better have the fstab settings correct or RHEL might fail to mount on reboot and thus halt in limbo.  It's for that reason, I normally don't make an entry in fstab but remount the device on reboots.

Nice thing about mounted data devices in virts ... they can be detached from server using ... then re-attached to another server.   Have done this very thing on Rackspace/Google CE setups.

2 cent - free advice!

You are talking about a Red Hat Enterprise Linux installation on Microsoft Azure, right? (Yes, I read somewhere that there are more Linux on Azure than all the other OSes!)

Changing partitions in a running system is a risky business. Generally, I don't know anything about Azure, adding new partitions are simple, expanding an available partition is also often supported. If you want to break an available partition in to many, that needs to be done outside the running system, in this case from the Azure control interface. You have to contact Azure.
