Still no need enlarge lun ?
> After you expand the volume capacity, you must manually increase the file system size to match. How you do this depends on the file system you are using. See your host operating system documentation for details.
E-Series does not control your Linux filesystem size. Linux does that.
If an E-Series volume is 20GiB and it's increased to 30GiB, Linux will see 30GiB.
If you see 30Gi then volume size has been increased as expected.
But E-Series cannot order Linux to increase filesystem size.
The Linux administrator needs to check the documentation and do that on the filesystem which uses that volume. The exact steps depend on filesytem type, volume manager, etc. That's why the documentation says to consult Linux documentation.
