See as example https://bugzilla.opensuse.org/show_bug.cgi?id=983221 "non-standard" DM targets do not appear to be autoloaded (the problem was hit with thin-pool, but it seems to apply to other targets as well). "Common" targets (like linear) are provided by dm-mod which seems to be autoloaded by virtue of /dev/mapper/control. Is it expected and intentional? Or are users required to manually load necessary modules on boot? TIA -andrei -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
