Are you still on 7.6 ? I recently discovered that a bug in sysstat was fixed in 7.7 that prevented autofs from umounting the filesystem. The following should show if it's taking into action: systemctl status mnt-backup.mount mnt-backup.automount systemctl cat mnt-backup.mount mnt-backup.automount Are you sure that you got no "," before that "noauto" ?

I commented out those entries in /etc/auto.master before modifying the fstab entry: UUID=259ec5ea-e8a4-465a-9263-1c06217b9aaf /mnt/backup ext4,x-systemd.automount,x-systemd.idle-timeout=15min noauto 0 2 which is exactly as it was before except for the x-systemd entries as you described. and the peculiar thing is it STILL does not automount. and yes, I did do systemctl restart local-fs.target. do I need to reboot (or something simpler, maybe) to fully disable the auto.master stuff? Thanks again!
