> This is interesting, partprobe seems to be an even lighter alternative. It seems that partprobe indeed also works for device mapper maps. Relevant links: * A commit to the (c)fdisk man page that suggests using kpartx or partprobe when the BLKRRPART ioctl fails (I wonder why that was not upstreamed): https://git.devuan.org/CenturionDan/util-linux/commit/c64061c9b306f2db49ba97d066b8487f66a914fa?w=1 * Some relevant Archlinux BBS threads, one commenter there even recommends kpartx over partprobe for some reason: https://bbs.archlinux.org/viewtopic.php?id=189537 https://bbs.archlinux.org/viewtopic.php?id=190672
