Couple issues found during 2.0 testing

In testing Proxmox VE, several issues were found.

Problem#1

I seem to remember fdisk issues being reported last year. See below for the problem accounting. Proxmox is a polished product. Although this is correctable by the user, this kind of issue should not occur.

Problem#2
All modern servers have 2 LAN connections on te Motherboard. Proxmox does not ask which adapter to be used for LAN to WAN service at installation time. Nor, does it do an auto-detect for where the LAN cabe is plugged.

These 2 items, you may want to address before you make Proxmox VE generally available.(GA)

All in all, the 2.0 beta looks very well. Thanks for this great work.

Thanks @Dietmar
I was referring to the message that is shown in the screen that reflects
"Disk device doesn't contain a valid partition table"

Thanks is the part about the polishing that I thought Promox would consider addressing. The message shown the results of the Proxmox install process....not by any user action or need.

Albeit small item to show you, it does raise eyelids when administrators see this because this need-not occur. Proxmox is a rather mature product.

How this helps

Hi,
but the system can't see an partitiontable on a single partition. That's normal also on other linux-systems.
Look this

[B]Disk /dev/md0 doesn't contain a valid partition table[/B]
Where no partitiontable is, they can't displayed...

Thanks @Dietmar. Did a little digging on these.
FDISK - fdisk is old. But, functional. (I think this is true) When fdisk creates a partition, it works on a cylinder boundary for partition allocation. Thus this warning does not arise. But, when other tools create partition, they create it on a block boundary. Here's why the problem exist. FURTHER, I have found that using GPARTED, I can create a partition on a cylinder boundary. When this is done, it averts the problem you have. I haven't used Parted in over 10 years so, I'm not sure how you would use parted at system build-time to create the partitions so that you skip this issues; but, I'm sure there's a way.

Other issue. I have found my instructions on how I fixed it the last time. I cost me 3 reboots, but system boots fast.

Now, I have a system where those messages do not occur. (Again, I wish I could give you more information on how you would do these things at build-time, but, because I am unfamiliar with your process for system build, I cannot help.

So, one is very easy for you to fix, the other probably will take a moment more in thought.

Hope this helps
