hi there since updating my system to include the following package...

# rpm -qi lvm2 Name : lvm2 Epoch : 8 Version : 2.03.12 Release : 6.el8 Architecture: x86_64

<snip> Build Date : Thu 12 Aug 2021 06:06:53 BST Build Host : x86-01.mbox.centos.org

...all LV commands just hang (pvdisplay / vgdisplay / lvdisplay / etc) which in turn is stopping dracut from generating the initramfs for the new kernel from the same update...

71464 pts/4 S+ 0:00 | _ /bin/bash -p /bin/dracut -f /boot/initramfs-4.18.0-338.el8.x86_64.img 4.18.0-338.el8.x86_64 71483 pts/4 S+ 0:00 | _ /bin/cat 71601 pts/4 S+ 0:00 | _ /bin/bash -p /bin/dracut -f /boot/initramfs-4.18.0-338.el8.x86_64.img 4.18.0-338.el8.x86_64 71602 pts/4 D+ 0:00 | _ lvm vgs --noheadings -o pv_name cs_ctream

( see dracut running the lvm vgs command...which never returns...so dracut nevern completes...so I can't boot into the new kernel )

any ideas on this one ? is it a known issue ? or is there anything else I can do to troubleshoot further ?

And when you downgrade lvm2, does it work again?
