Ok, where did GUI system-config-lvm go? in rhel 7, centos 7, Oracle Linux 7?
Not sure where the GUI went and why but, you can’t install the package anymore, at least to my knowledge not in RHEL 7 and it’s clones. I
New command line utility with systemd / RHEL 7 is being provided named “ssm”.
You can install it with:
yum install system-storage-
It does a lot of the thing that the “pv” and “lv” legacy commands did in one command – the legacy command lines (e.g. pvcreate, lvcreate, etc.) are still there too. Makes using chef a lot easier I would assume.
So here is how I finally created a new logical volume and mounted it – from root – assuming the disk I’m adding is under /dev/sda.
