Re: [CentOS] expand physical volume

The one and only partition on your device (sdb1) has the old size. That is, there's free space on sdb. You have to either 1) create a partition sdb2 (and then a pv on it etc.) or 2) resize the partition sdb1 (then resize the pv etc.).

I'd pick #1. remember to reread the partition table after creating the partition (partprobe /dev/sdb or similar) before doing pvcreate on sdb2.

The all you have left is to add the pv to your vg, resize the lv (or create a new lv, whichever...). And finally resize the filesystem in the lv.

Hi Peter,

How do i resize this partition? parted seems to want to resize the file system also and i think this would make some troubles. I thought pvresize would do this in one step?
