I am trying to resize a centos (5.2) VM drive. I use VMware and I have increased the size of the drive by 40G. I am running resize2fs on /dev/sdb1 (which is my root partition) but when I do I get this error:

[root@centos ~]# resize2fs /dev/sdb1 120G resize2fs 1.39 (29-May-2006) The containing partition (or device) is only 19970795 (4k) blocks. You requested a new size of 31457280 blocks.

How can I change the block size?

I have also tried to use gparted live cd but it will not allow me to increase the size even though it sees 40g of unused space. I can only create a new partition.

Any help would be appreciated.

I just ran into same kinda of thing and I for one found much easier to create new virtual 40gb drive, restore backup, drop old drive, use new one. done.

If anything goes wrong you still have old virtual drive you can go back to.

After having resized the virtual drive have you also resized the partitions inside the VM? Doing a "fdisk /dev/sdb" will probably show you a 40G drive but the partitions will still have the old size and you need to extend them before you can extend the filesystems on them.
