Error Restoring GPT Partition Tables
-
@george1421 I forgot I still had one of these up and running. It looks like the firmware for the MOBO is not at latest version, and the BIOS is also not at latest version. Not sure about NVME firmware. I think this is the 981 which is an OEM version of the Samsung 970, but not sure if the same firmware applies.
-
@tlehrian What I’m trying to rule out is if its a Lenovo thing that is causing the drives to switch, I don’t think it is, but I wanted to rule out hardware (or stale firmware) as the culprit.
As for the question about bios (legacy) mode. I wanted to see with the same physical hardware, is the device swapping location related to the uefi firmware to see if it does the same thing in bios mode.
Right now I’m looking at this as I don’t know where the issue is. So I’m trying to rule out where the problem isn’t first to get the number of possibilities down.
-
@tlehrian Is the inital issue solved at all? I seem to have lost track of that part of the discussion.
-
@Sebastian-Roth Thanks for asking!
The initial issue was that we were receiving the error restoring GPT partition tables sometimes on these particular machines. We have two NVME M.2 drives on these machines, that we now know are becoming available seemingly randomly based upon a race condition as to which one becomes available to the OS first. Our drives happen to be different sizes (256GB/512GB), and we want the larger drive to be the primary drive with the OS installed, and the smaller drive to be an extra storage drive. I have set up an image as Multiple Partition - All Disks (not resizeable) to deploy to these machines. Also, these machines are booting UEFI, without secure boot.
If the correct drive wins the race, the image goes through swimmingly. If it doesn’t, I get the error that started this thread as the drive it’s trying to restore the partition tables to is not large enough to hold the image.
So, long story short, no. But that’s OK because now I know what’s causing the issue, and although it’s a bit annoying, I can work around it knowing that it’s not a larger hardware issue. And I’m happy to help troubleshoot to try to get to a resolution for it, as it would benefit me greatly as this setup composes about 25% of my lab deployments at present.
-
@george1421 Sure. I understand about narrowing down the possibilities. I can switch one of these to legacy and see what happens with the drives. To be clear, these are HP workstations with Samsung NVME M.2 drives. Are either of those companies related to Lenovo in some way?
-

Sorry I’m working on too many threads at the moment. I got the threads mixed up with similar issues.
-
@george1421 No worries. Just making sure there wasn’t something you knew that I didn’t
-
@george1421 I placed one of these machines in legacy mode to see if the drives would exhibit the same behavior and ran the tests you prescribed earlier. Indeed, after two reboots, they did switch, so we can probably rule BIOS type out. Here are the outputs:

Right yeah. I just totally lost the string here. When reading some of the messages I had the impression that there was another poblem causing this. No worries.
-
@tlehrian Thank you for taking the time to help us debug this. Without the hardware the developers rely on good quality feedback from you guys.
Ok so we are down to firmware on the computer and firmware on the drives them selves (if that’s a thing).
Something else I’m thinking about (just out loud at the moment) does a commercial linux distribution like ubuntu or centos do the same thing? If it does then it should fail to boot every second time or so if the drives are swapping position. If it boots correctly every time how do it do that? Just thinking about a computer when it cold boots it looks to the bios to find which drive to boot. The reference for uefi is disk/path/file. It doesn’t (at the point of cold boot) know anything about uuid so how does it find the boot drive? (assuming that it works every time)
-
@george1421 If you actually install Linux, it will generally mount it using the UUID, which should always be the same.
As for the BIOS, the PCI path doesn’t change for NVME drives, just which one initalizes first can be volatile (and thus the block naming scheme in Linux gets messed up). BIOS looks for the boot file on the PCI path afaik.
However, I’d be interested in seeing if this issue occurs on successive Ubuntu/Centos LiveCD boots
-
@Quazz I was curious about the LiveCD thing, so I tried it. I can confirm that it DOES reorder the drives on successive LiveCD boots.
lsblkswitched the drive order after one successive boot.In fact I think I ran into this when first installing the OSes on these machines, and thought it was weird when it happened, but didn’t think much of it at the time.
-
@tlehrian Ok so this IS something that the Linux kernel developers are going to have to address. Its not something that only impacts FOG, but all distros of Linux.
-
@george1421 said in Error Restoring GPT Partition Tables:
Its not something that only impacts FOG, but all distros of Linux.
As @Quazz said, distros don’t have that issue because they mostly use UUIDs to identify partitions. Once the identifier is set and configured in your grub.conf/fstab there is no issue finding the right one again. But we can’t do that as we need to identify the whole disk, one that we possibly have never seen before (fresh machine).
So I kind of understand why this topic is not being discussed in the Linux world too much. But I am still wondering why this is the case for NVMe drives and if there is a way to query the controller itself. Within FOG we can do a lot of things. We can even implement our very own low level tool in C to query that information for us.
-
@tlehrian Can you please run the following commands in a debug session on one of your machines:
basename $(readlink /sys/block/nvme0n1/device) basename $(readlink /sys/block/nvme0n1/device/device) basename $(readlink /sys/block/nvme1n1/device) basename $(readlink /sys/block/nvme1n1/device/device)I borrowed that from this script. As well referenced in this topic.
I am wondering if the so called BDF (bus/device/function) notation is consistent across reboots.
Edit: Quite possibly the BDF will also change. Reading the section on “PCI Bus enumeration” in this wikipedia article I can imagine that it’s just the nature of those kind of devices.
Edit 2: Hmmmmmmm: https://superuser.com/questions/488833/do-pci-pcie-buses-and-devices-always-enumerate-in-the-same-order (not sure if this applies to PCIe NVMe devices at all)
-
@Sebastian-Roth I’m sorry it took me so long to get back to this, but I was able to run the testing this morning. It does appear that the device names stay consistent, even though the drives may change order in
lsblk. Here are my results:State 1

I am busy getting ready for our Fall semester to start next week, BUT…
I will keep a debug task set up for one of our machines in order to do more testing for you all if need be. I’m glad to be part of the solution here, and I promise not to take as long to respond back to a testing request next time…
-
@tlehrian Just wanted to let you know that I still have this on my list but just don’t get to it.
-
I’m just checking back on this (rather old) topic to see if any headway had been made. It seems the last tests I ran indicated that the
basenamecommands did indicate the device names remained consistent even when the OS switches them. I won’t need to image these again for a while, but would be nice to see if a fix is available.Thanks!

@tlehrian Great you are bringing this topic up again. Even though I try to keep track of all open topics I still miss one or the other sometimes.
Which version of the FOS inits do you currently use?
