LVM free space problem after resizing the logical volume

wdorninger · 11-06-2009, 08:00 AM

Hi all,

I have an urgent question regarding lvm. A bit of history first. I'm using VMware and had a harddrive with 20GB which I resized to 30GB. These are the steps I followed to resize the disk, volume and filesystem after resizing the disk in VMWare:

(1) fdisk delete partition and recreate it
(2) pvresize /dev/sda2
(3) lvresize -L+10GB /dev/mapper/VolGroup00-LogVol00
(4) resize2fs /dev/mapper/VolGroup00-LogVol00

Well so far so good i saw that fdisk shows that the space is available and I thought its fine - however now when i try to pass the 20GB mark my filesystem switches to read only. So I had a look and realized that the physical volume shows that its full...

How can this be? - Is there a way to adjust this? Any suggestions how to solve this? - I'm pasting the fdisk, and lvm output below.

Thanks a lot,
Walter
