Exam EX200 topic 1 question 53 discussion

They identify the LVM as mounted; which indicates that there is an associated FS. You'll wanna make sure that unmount first, and then resize the FS as well. This can easily be done by adding the additional -r switch in the command: lvextend -L +5G -r [/dev/vg/lvm] If you forget this step, you can also run resize2fs or xfs_growfs

My take on this => i think it being misinterpreted => i believe questions is saying that there is 5G of free space on disk unpartitioned and NOT the VG or LV which is common scenario and based on this this is how i would go about it * Step 1 => create parition for the remaining space using fdisk i.e. fdisk /dev/sdd => n > primary 2 > except default -all space => type input 8e => w to save and exit * Step 2 => pvcreate /dev/sdd2 => prepare partition for LVM * Step 3 => vgextend VG_NAME /dev/sdd2 => adds the /dev/sdd2 (Partition/Block) to the existing VG where LV exists * Step 4 => your choice either lvresize or lvextend and DO NOT forget option -r to avoid doing double steps i prefer lvextend=> lvextend -l 100%FREE -r LV-NAME in this case (lvtestvolume) => this will take all available FREE space available in the VG and hence meets the requirement

--assume new disk is src pvcreate /dev/sdc vgextend test0 /dev/sdc vgs lvs lvextend -r -l +100%FREE /dev/test0/lvtestvolume --in above command because we are going to use 100% of 5GB disk we specified +100%FREE. Below two commands i am adding however i didn't have to use the because while using -r in above command volume is already resized and automatically fle system type is matched to that of the existing volume. xfs_growfs /dev/test0/lvtestvolume -----in case of xfs file system resize2fs /dev/test0/lvtestvolume -----in case of ext2, 3 or 4 running above command will produce following: The file system is alread ________ blocks long. Nothing to do! --run df -Th command to check size.
