Fyi... I get the following error when I run "partprobe /dev/mapper/name" as non-root on Ubuntu 20.04.
$ partprobe /dev/mapper/name /dev/mapper/control: open failed: Permission denied Failure to communicate with kernel device-mapper driver. Incompatible libdevmapper 1.02.167 (2019-11-30) and kernel driver (unknown version). A bug has been detected in GNU Parted. Refer to the web site of parted http://www.gnu.org/software/parted/parted.html for more information of what could be useful for bug submitting! Please email a bug report to bug-parted@gnu.org containing at least the version (3.3) and the following message: Unable to determine the dm type of /dev/mapper/name. ---- I did not expect partprobe to work as non-root. But I did expect a terse(r) error message. For example, the following error message is expectedly terse. $ partprobe /dev/sdf Error: Error opening /dev/sdf: Permission denied
