GPT disklabel and partition alignment about chef-gluster HOT 6 OPEN

Thanks! I will take a look at it

We just ran into this problem :( Definitely causes issues when trying to add a drive > 2TB.

@bushong1 in the pending rewrite, LVM is used instead of fdisk

from chef-gluster.

Please consider creating GPT disklabel regardless! The recommended setup for LVM is to use a partition spanning the whole disk for the PV anyway.

It would probably be as easy as including "package parted" and modifying the old fdisk commands in the recipe.

@bjozet LVM uses pvcreate, not fdisk

@shortdudey123, The lvm-cookbook doesn't seem to take alignment into consideration, and that is kind of the point of this issue. Yes, you can use pvcreate on a raw device without partitions on it. To get alignment, pvcreate needs proper arguments to it, which i didn't see in the lvm-cookbook (although, i might have missed it, didn't look too long), hence my suggestion to use "parted" to create an aligned partition first, together with a GPT disklabel. Or this whole alignment issue could be filed against the lvm-cookbook.

I'm not gonna argue a lot about it, since i'm not using the gluster cookbook, I just happened to get the notification when there was activity on the issue.

Which ever way you choose to go, good luck! :-)
