Hi all
I accidentally deleted a LVM volume directly (rm /dev/System/newcpanel)
and
now my LVM's are all messed up.
You might find that /dev/System/newcpanel was merely a symlink to /dev/mapper/System-newcpanel
If the /dev/mapper entries exists, you can try recreating the symlink.
Otherwise you could try deactivation and reactiving the System volume group ("vgchange -a n System", "vgchange -a y System").

Both the symlink, and the actual file / device was missing, but I've been able to rename newcpanel to oldcpanel - yet I still can't remove it.

As you can see the System Volume Group is the main VG with root as well - so, what will happen when I deactive & reactive System while the server is running?
