Hello Everyone,
We have two virtual machines running CentOS 7, one for file sharing and one for email. Both base Filesystems run BTRFS. I need to convert both filesystems over from BTRFS to ext4.
Both guest VM's are in a vmware environment on the same server. The file server has 2.8 TB of space total allocated to it, 2.1 TB of total used space
The mail server has 2TB allocated to it, and 982 GB of total used space.
The host it is attached to has 13.97 TB of total usable space, with 3.4 TB free.
What steps would you go through to migrate the file systems over? Would you set up a duplicate VM and rsync data over? Expand the capacity of the existing VM, add a new partition then move data over from one partition to another from within the same VM?
What are your thoughts?
