Summary: fsck.f2fs version 1.14.0 has an error when not /dev/vgXX/lvYYY path provided: "ASSERT] (init_sb_info:1017) !strcmp((char *)sb->devs[i].path, (char *)c.devices[i].path)"


Comment: only /dev/vgftp1a/VIRTUALa goes ok, the rest from the list below (including /dev/dm-15) throws an error.


Problem: when fsck enabled in /etc/fstab (6th field is non-zero value), bootup fails due to FSCK error (OS Gentoo)
