Hello Peter,
Peter Boy [2021-04-17 19:33 +0200]:
I just installed F34 Server build 20210416.
(Fedora-Server-dvd-x86_64-34-20210416.n.0) and tried cockpit.
Under 'Devices‘ there are no devices listed and the menu button in this section only
shows „create RAID device“.
Usually there are the volume groups listed (among others) and I can create a new LV.
Do you have udisks2-lvm package installed? It's a recommends of
cockpit-storaged.
