Created attachment 112022 [details] kde-partition-manager-no-bitlocker-labels When a bitlocker volume is unlocked so you can access the filesystem, you can read both LABEL and PARTLABEL with: sudo lsblk -o name,mountpoint,label,partlabel,size However if it's still locked (no password or key provided hence is secured) apparently lsblk can't read the LABEL, but there's a workaround: sudo dislocker-find | xargs sudo dislocker-metadata -V KDE Partition Manager shows none of them on the UI, see attachment.
I've reported the bug to util-linux in case they want to implement it internally which would be better... https://bugzilla.redhat.com/show_bug.cgi?id=1567498
PARTLABEL should be working. PARTLABEL has nothing to do with file system. PARTLABEL is read from GPT partition table. I think your Partition Manager is too old to show PARTLABEL, but it is already implemented in git. It was actually reading it for some time, just there was no GUI to show it.
