Thanks for the guide! It helped me a ton. A potentially easier approach could be to create a new virtual disk and add it to the LVM, instead of resizing the one you already have. But at any rate your guide worked for me – and I can report that using Mike Karolow’s suggestion is also successful. Thanks again!

Thanks Chris, your script really helped me. We are extending disk using LVM as mentioned above but instead of adding a new disk, we extend existing disk and create a partition on it and add to LVM. We always needed to reboot, so that the extra disk space is available. But Chris’s script really did it without rebooting. I have used forcerescan option and finally it boils down to the following
echo 1 > /sys/class/scsi_device/0:0:1:0/device/rescan
Also after creating a partition, when we ran pvcreate /dev/sdb2 we got an exception saying that /dev/sdb2 in not recognized or filtered out. I ran partprobe and pvcreate worked afterwards without problems.

If you are adding a new disk, you can make it detected using following command:
echo “- – -” > /sys/class/scsi_host/host0/scan

You might need to replace host0 with proper value.

ThankyouThankyouThankyou
I know naff all about Linux so most online help is way over my head or assumes prior knowledge of the OS.
You’ve pitched this guide at exactly the right level for me which is a life saver. After trying on a test system we just extended a live virtual DB server – no problemo.
Thanks again.
