NethServer Version: 7.6.1810
Module: OS
I have recently installed a new 7.6 to use as a nas to backup our data.
I have noticed, after having installed at the customer site, that lv_root is 227 Gb instead of 3Tb
I have 4 1.0tb hard disks, and I cannot figure out how to exapnd lv_root because of the default raid configuration.
How can I expand lv_root without reinstalling everything?
Can someone help me?
