If it's CentOS 4.4 box you should be fine. I could dd it back and start from scratch. I see that fdisk must be run to resize the partition, then run pvresize. I was under the impression that changing the partition with fdisk will lose any data on it? Here's what I have. Yes, I am running LVM2, latest updates on Centos4.4: # fdisk -l Disk /dev/hda: 41.1 GB, 41174138880 bytes 255 heads, 63 sectors/track, 5005 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/hda1 * 1 13 104391 83 Linux /dev/hda2 14 2501 19984860 8e Linux LVM # pvresize --test /dev/hda2 Test mode: Metadata will NOT be updated. Physical volume "/dev/hda2" changed 1 physical volume(s) resized / 0 physical volume(s) not resized # fdisk /dev/hda2 Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel Building a new DOS disklabel. Changes will remain in memory only, until you decide to write them. After that, of course, the previous content won't be recoverable. The number of cylinders for this disk is set to 2488. There is nothing wrong with that, but this is larger than 1024, and could in certain setups cause problems with: 1) software that runs at boot time (e.g., old versions of LILO) 2) booting and partitioning software from other OSs (e.g., DOS FDISK, OS/2 FDISK) Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
