LVM2 activation error

[holdemaisoftware]

I hope this is the right place to ask help regarding issue I am having and what to do to access my pve/data again so that I can recover some data that is inside one of the VM's before rebuilding proxmox (if neccesary)

Do anyone know why I am having LVM2 activation error on bootup, here is the full systemctl status lvm2-activation.service

Hi,
do you have defined any filter in /etc/lvm/lvm.conf?

And 83 volumes are active... what is the output of "lvs"?

This would have to remain a mystery for now however I had no specific filter in lvm.conf

I ended up doing lvconvert --repair pve/data and even though Im not sure what it fixed I ended up being able to reboot and access the one VM that I really needed to recover data from. After reboot I still received the same error log about lvm2 activation but finally managed to access only the VM I specificly wanted to recover data from, extreme luck on my side.

I am now rebuilding the whole proxmox server without fully knowing the details about the lvm2 error, I really hope I dont ever get that again but if I do I will return here.
