They're both the "same" custom config. I tried: # echo 200000 > /sys/devices/virtual/block/md7/md/sync_speed bash: /sys/devices/virtual/block/md7/md/sync_speed: Permission denied # id uid=0(root) gid=0(root) groups=0(root) This used to work. Any ideas as to what I could have set wrong? I haven't a clue! Is there a security debugging tool or a log-file I could use to trace this down? Thanks, David
