Once that is applied: # udevadm info /dev/sdb | grep ID_FS_TYPE (no output) # udevadm info /dev/sdb3 | grep ID_FS_TYPE E: ID_FS_TYPE=LVM2_member This has been observed on Ubuntu bionic. $ apt-cache policy util-linux util-linux: Installed: 2.31.1-0.4ubuntu3.7 Candidate: 2.31.1-0.4ubuntu3.7 Version table: *** 2.31.1-0.4ubuntu3.7 500 500 http://gb.archive.ubuntu.com/ubuntu bionic-updates/main amd64 Packages 500 http://security.ubuntu.com/ubuntu bionic-security/main amd64 Packages 100 /var/lib/dpkg/status 2.31.1-0.4ubuntu3 500 500 http://gb.archive.ubuntu.com/ubuntu bionic/main amd64 Packages $ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 18.04.5 LTS Release: 18.04 Codename: bionic On Ubuntu focal an ID_FS_TYPE is also incorrectly reported for the whole disk but the information for individual partitions seems to be correct although I don't have a system with same partition table from the example. I haven't yet tried with the util-linux patch in focal.
