That is precisely my rationale. We’re using ESXi; resizing a disk is a trivial event that makes more sense for our environment.
I also agree with Tom on the training piece. Woe be unto the admin who blindly uses a disk without any investigation and/or verification. Training junior admins to understand all of the possible configurations and to look before they leap are key parts of said training… -Andy From: kickstart-list-boun...@redhat.com [mailto:kickstart-list-boun...@redhat.com] On Behalf Of Callahan, Tom Sent: Tuesday, May 03, 2011 5:45 AM To: Discussion list about Kickstart Cc: Discussion list about Kickstart Subject: Re: Use entire disk as PV. Most storage arrays can grow existing disks, which doesn't work as nicely if the disk has a partition. Making a PV out of the entire disk allows much easier PV/VG/LV expansion, without mucking with a partition table. As for the training piece, I'd expect an admin would do some verification a disk is not in use before blindly assuming it's not in use, and overwriting data. There is no standard practice with how to create a PV, it depends on the site.

The reason for doing this would be to make PV resizing a bit easier for virtual machines. Otherwise, I must muck around with the partition table and blah blah … not a show-stopper, but potentially dangerous for junior admins. I suspect that the functionality just isn’t there… but does anyone know the magic syntax to get it to use the entire drive (aka. /dev/sdb) as a PV during kickstart? Why do you need to resize PVs for virtual machines? You allocate the extra space to your VM as another virtual drive or partition, then using LVM create another Physical Volume for that drive, add that Physical Volume to your Volume Group and Logical Volume, and extend the filesystem. No mucking around with an existing partition table. I would be confused if I encountered a disk without a partition table – I’d probably assume it wasn’t formatted at all. Better to train your junior admins in standard practice?
