Topic: After resize, df does not indicate increased size.
I am running VirtualBox on Windows. I created a GParted VM so that I could expand an 8GB partition to 10GB on a Red Hat Enterprise Linux (RHEL, developer server, self-support subscription) VM server, also on VirtualBox. Everything seems to have gone well. In the GParted graph, you can see that the unallocated space (white) of /dev/sda2 was added to the allocated space (yellow). However, when I booted the Linux VM, "df -h" shows the same space used as before the expansion.
"pvs" had a value for PFree. After running "lvextend -L +2G /dev/mapper/rhel-root", the value for PFree changed to 0, as expected. Maybe I should have used lvresize? When I try lvresize now (same arguments), it says there is not enough space. Maybe undo lvextend? Just making some guesses.
The size of /dev/mapper/rhel-root did not change as expected:
[sbrown@localhost ~]$ df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/rhel-root 6.2G 5.3G 937M 86% / devtmpfs 481M 0 481M 0% /dev tmpfs 497M 0 497M 0% /dev/shm tmpfs 497M 7.0M 490M 2% /run tmpfs 497M 0 497M 0% /sys/fs/cgroup /dev/sda1 1014M 160M 855M 16% /boot tmpfs 100M 4.0K 100M 1% /run/user/42 tmpfs 100M 48K 100M 1% /run/user/1000
Any help would be truly appreciated.
