lvextend command - will it destroy existing data
Hi All,
I am having a linux system running on OEL 5.7 in production environment.
at /etc/oracle-release
Oracle Linux Server release 5.70
I already have a /u02 mount and wanted to add additional disk space to it. The actual HDD for the server is 600GB but only 400GB is being used used and partitioned. The remaining 200GB is the capacity that not yet configure to any of the system file or shared use. i am using below commands to add space to my volume group.
implement step
1. lvextent -L +200G /dev/mapper/osvg-u02.fs
2. resize2fs /dev/mapper/osvg-u02.fs
3. df -h
Will this lvextend command lose/destroy or corrupt any existing data which is residing in /u02 mount now ?/
Anybody seen such issues ?
Please help.
