How do I extend a LV and filesystem, as well as the underlying storage in conjunction with a lun expansion?
Issue
- A LUN has been extended and we need to get the OS to recognize the new storage space
- Both the block device and multipath devices need to be resized
- We need to extend our pv, vg, and lv which are using the entire device, not partitions
- We need to extend the filesystem
- Underlying device of the PV has been extended from storage end. How to get the additional size reflected in the PV, VG.
- How to extend a
Thin Logical Volume?
Environment
- Red Hat Enterprise Linux 5, 6, 7, 8 & 9
- Filesystem: Ext2/3/4/xfs
- LVM Physical Volume (PV) is on whole disk (no partitions)
