Missing creation time for LVM logical volume

[malinal]

Hi,

One of our storage has an lvm volume group on which multiple logical volumes are not set the creating host name and time (LV Creation host, time attribute).
These were created quite a long time ago, but unfortunately (since the date is missing) I can’t say exactly. It can be many, many years, even 8-10.

Currently, we want to pull it under a Proxmox 6 (shared lvm via fiber, currently used by Proxmox 3), which we can’t do because Proxmox 6 needs creation time.

I couldn't find a command to set an exact time for this.
Can anyone help me how to set the hostname and creation time on an lvm logical volume?

Regards,
Laszlo

Could someone help me?

So, lvdisplay output example ( 1 volume, but there are 32 in total, 5 of which have no creation time):

LV Creation host, time attribute is empty.
Probably, created under proxmox 3 - is it possible that this attribute did not exist then?


--- Logical volume ---
LV Path /dev/stvg1/vm-103-disk-1
LV Name vm-103-disk-1
VG Name stvg1
LV UUID sbSgG8-4nuw-RwG5-skxe-J9e1-OkGo-ImEMfO
LV Write Access read/write
LV Creation host, time ,
LV Status available
# open 0
LV Size 1.50 TiB
Current LE 393216
Segments 1
Allocation inherit
Read ahead sectors auto
- currently set to 256
Block device 253:20

and proxmox error message when trying to read lvm volumes

I ran into the same problem and couldn't find a way to add the metadata to the LV. So what I did was to move (from inside Proxmox) all the LV:s (I had 4-5) to another storage area and then back again. Then new LV:s got created with the appropriate metadata.

Small bump, got the same issue. Moving LV is not a preferred option.
Anyone that can hint me to another solution?
