I am stuck in pretty weird situation. I hope somebody here will help me.
I have one centOS server with XEN installed on it. XEN has 3-4 virtual machiens running on it. As required by XEN, this server has LVM implemented. The structure of Disk System is as following ( Kindly click on this image link) :
This server has two disks of 750 GB each, and RAID implemented. MD2 partition is / (root) filesystem. It has only 10 GB of space. Now i have to increase the space of / filesystem. It is running short on space. Some more information about server is following:
- It has 1 volume group named xen in its LVM and its size is 682 GB.
- Their is a physical volume named md3 in volume group xen and its size is 682 GB.
- This physical volume has 5 logical volumes which are used for XEN virtual machines.
This volume group has 400 GB of free disk space. So i want to extract some space (200 GB)from it and use this space for / (root) partition.
This is a live server and i can not take risk of testing some test methods on it. I have searched for 4-5 hours for this issue but i was not able to get the proper and authentic answer. So i thought i should post my question here so that i can get a authentic answer.
This is very urgent, my client is shouting on me. .
one more thing i have no physical access this server as it is located in another country.
Kindly help me to solve this.
