PV is using old PV header

grepo · 10-30-2019, 04:02 PM

Hello,

since I upgraded Fedora 30 to Fedora 31 I receive warning when running lvs:

WARNING: PV /dev/md4 in VG vg02 is using an old PV header, modify the VG to update.

How should the VG be modified? I cannot find anything relevant.

Thanks

Marek

Hello,

just found out:

vgck --updatemetadata vg02

Thanks for posting back - wonder if I'll remember this should I need it ...

I did this fix just now on an Ubuntu 20.04.1 install that's been upgrading along since Ubuntu 16.04 when the VG was first created. Worked flawlessly.

I have the same issue but when I tried running vgck --updatemetadata vg02 I got the message, "permission denied." Can you explain how you did this? I'm attaching a screenshot of the result of this.

Try running it as root.

I've attached a picture of the message I get on startup where I get a warning about an old PV header. I'm also attaching a screenshot of the message I get when I try fixing this. I ran the program as root but it didn't work. Can you tell me how to fix this? Thanks!

run it as root or use sudo

I ran it as root and got this message:

Cannot process volume group vg02

I'm attaching the original warning if that helps.

You need to make an effort to understand commands you are running on your system. Blindly using commands can lead to fiasco - you're lucky in this case it merely failed.
Check the manpage - it needs your vg as mentioned in the messages.

You need to take special care you understand what you are doing when it comes to hard drives. As @syg00 said, Copying and pasting without an understanding what the command(s) do could render your system inoperable - or even worse, data loss!

You Volume Group is listed in the warning: ubuntu-vg

Code:

vgck --updatemetadata ubuntu-vg
