Extend root partition on SuSE enterprise Server 11.1
Hello Folks,
Greetings,
I am in need of extending the / partition for one of my SuSE linux Enterprise Server 11.1 which is running on VMware. I will be able to extend the virtual lun from the vshphere console but not sure how to extend the root partition from the OS end. I am not sure if I could do it online. Please see the below o/p from the server. This is an Oracle server.

Is there any SUSE enterprise 12 x86_32 version available? I have SUSE enterprise 12 x86_64 and I am unable to compile 32 programs in that. It looks to be that gcc compiler (32 bit) does not come with SUSE 12. How can I get that?

Hi,
I need to extend a soft partition from 20G to 100G. New disk is already added as a meta device. This soft partition is already assigned to a guest LDOM. Can someone let me know the steps to increase soft partition so guest LDOM can recognize the new space.
