[Devil-Linux-discuss] big lvm-pv not visible after restart

[Udo L. <udo...@al...>]

Hi,
I have an strange issue with devil-linux 1.6.2_x86-64.
The machine run virtualized on proxmox-pve (kvm) and has two HDDs 
assigned, one normal sized for devil-linux and a big one for archive-data.

On the big-one was an gpt-label and is also used for lvm2. During the 
tests all runs fine, so I increase the big volume (7T) - after resizing 
the partition no lvm-info was accessible. Perhaps there goes something 
wrong. I create a new gpt-label, pv, vg and lv and resync the data again.
But after an reboot all data was gone...

If I start the machine with an grml-live-cd the lvm-data is there.

On devil-linux I can't see any uuid on the big partition - exept I 
change the partition-table with parted - after that the blkid is visible 
and lvm is working!!

The same happens with ide-disk instead of virtio.


Any hints?

Best regards


Udo
