Hi,
We have a RHEL AS3 server.
I want to execute the following command to reduce logical volume space.
Will it destroy the data Please advice.
"e2fsadm -L -15G /dev/vg00/backup"
I want to increase the /logs by 15GB. That is what I am planning to do.
Find below the output of few command related to my query.
