Hi
My Harddisk LED is blinking about once every second. This is not really a critical problem, but it's just annoying me cause it's clearly too often.
I read the topic https://bbs.archlinux.org/viewtopic.php?pid=765666 but none of the suggested worked here.
Can't identify a process with iotop and vmstat does not notice these accesses either.
Further I have noatime and now even commit=60 in my fstab.
I tried to stop all daemons, exept network and ssh I need to connect, and stopped X but it had no effect. Lastly I killed systemd-udevd, without effect.
I use ext4, this may be the problem ?
Here's my "normal" ps ax (with daemons etc.):

I see [ext4-dio-unwrit] and [kworker/1:0] for example, but these are kernel processes I suppose ?
No idea about them... I have.

Try to remove 'defaults' from fstab. Optionally, have you tried disabling barriers temporarily? (barriers=0 in mount options)

Unfortunately, no luck. I tried what you suggested:
iotop -Pao doesn't register these flickers.
It shows jbd2/sda3-8 but not that often, I would say it's fine.
It's only a very short flickering, I can't hear anything. So, I don't know if there's really something written...
I tried removing defaults first and even put barriers=0 in but it had no effect...
Dunno, it's strange...
here ps ax w/o daemons etc... (exept ssh and network i need)

So, it has to be one of these...?
Thanks anyways !

Well my server has both of those daemons running and does not blink once a second. Here's my fstab if it helps any:
UUID=x / ext4 noatime,errors=remount-ro,data=writeback 0 1
UUID=x /boot ext2 noatime 0 2
UUID=x /home/torrent btrfs compress=lzo,noatime,autodefrag,inode_cache,space_cache 0 0
UUID=x /root/VirtualBox\040VMs btrfs defaults 0 0
none /tmp tmpfs size=2G,nodev,nosuid 0 0
I think noatime could help out.
