If you are using “whole-disk” mounts on your Cloud hosting
i.e. /home is on /dev/sdb

Then you can resize the physical volume if you increase the size of the LUN, by using

pvresize

If you partitioned it and are using /dev/sdb1, then you will need to delete and recreate the partition, but if you are using “whole disk” a pvresize and resize2fs should be sufficient.
