NEW QUESTION # 31
One Logical Volume named lv1 is created under vg0. The Initial Size of that Logical Volume is 100MB. Now you required the size 500MB. Make successfully the size of that Logical Volume 500M without losing any data. As well as size should be increased online.
Answer:
Explanation:
see explanation below.
Explanation
The LVM system organizes hard disks into Logical Volume (LV) groups. Essentially, physical hard disk partitions (or possibly RAID arrays) are set up in a bunch of equal sized chunks known as Physical Extents (PE). As there are several other concepts associated with the LVM system, let's start with some basic definitions:
Physical Volume (PV) is the standard partition that you add to the LVM mix. Normally, a physical volume is a standard primary or logical partition. It can also be a RAID array.
Physical Extent (PE) is a chunk of disk space. Every PV is divided into a number of equal sized PEs. Every PE in a LV group is the same size. Different LV groups can have different sized PEs.
Logical Extent (LE) is also a chunk of disk space. Every LE is mapped to a specific PE.
Logical Volume (LV) is composed of a group of LEs. You can mount a file system such as /home and /var on an LV.
Volume Group (VG) is composed of a group of LVs. It is the organizational group for LVM. Most of the commands that you'll use apply to a specific VG.
* Verify the size of Logical Volume: lvdisplay /dev/vg0/lv1
* Verify the Size on mounted directory: df -h or df -h mounted directory name
* Use: lvextend -L+400M /dev/vg0/lv1
* ext2online -d /dev/vg0/lv1 to bring extended size online.
* Again Verify using lvdisplay and df -h command.
