I have a Linux Red hat 5 server installed and configured Zimbra open source email. This server was installed and configured before I joined the company. Now, the root partition has only 20% disk space and the rest of the space was set as a partition for /home. The server is running very well and perfect but now root partition has only 10% free space.
Is there any way to move some of space like 100-200 GB back to the root partition without data loss and corruption?
If yes, please provide steps, package name(s) or names of 3rd party application?
Thanks in advance.
