[toni@toni ~]$ I have resized (using lvresize -L amount logical_volume) the logical volume lvolroot, now it has 85GB as last command shows. Also I have resized lvolhome but if I launch below command sizes do not match with those shown by pvs or lvdisplay:
[toni@toni ~]$ LC_ALL=C df -hP | column -t

[toni@toni ~]$ Why sizes do not match?
I mean lvdisplay shows 55,00 GiB of size for lvolroot and 85,00 GiB of size for lvolhome but this last command (df) shows 30G for lvolroot and 79G for lvolhome. Why? They do not match.
EDIT: I have solved by executing below command missed:
resize2fs /dev/VolGroup00/lvolhome
resize2fs /dev/VolGroup00/lvolrootSorry, I forgot last command.....
