Possible to extend a partition allocated to a PV/VG/LV with LVM ?

[RimBlock]

Hi,

I have a CentOS virtual machine that was built with a 8GB root partition (LVM LV).

I have more space available on the SSD the VM files reside on and would like to extend the root partition.

I know I can create another virtual disk, assign it, partition it, create a PV, assign to a GV and resize a LV with it to allocate the extra space but rather than have two virtual drives pooled via single VG I would rather extend the first drives available space in ESXi. Can I extend the partition etc if it is allocated to a PV without loosing the data and if so is there any special tricks / issues that would help / I need to be aware of ?.

Thanks
RB

You could probably use gparted to resize the underlying partition and go from there, but volume groups are designed exactly for grouping PVs together, so I would just do that .

I have already and so added a second virtual disk, added it to the VG and extended the LV.

The problem is that I would like to move the VM to a new disk and I can use most of the disk for a PV rather than multiple chunks of the disk, just to tidy it up really. It is not really a requirement but just housekeeping.

Maybe I will stick with that then.

Thanks
