<pre wrap="">I have an IONITX with a solid state disk (SSD) as a front-end. I have
moved /tmp and /var/log to RAM drives in tmpfs to prevent frequent write
activity to the SSD. I had expected very little drive activity to be
reported (as viewed by watching the HDD LED activity light) - however,
it's still fairly busy and seems to have a pattern of activity.
I need to figure out if there are processes still writing elsewhere to the
system on a regular basis. I will either turn off the processes or direct
their activity to another tmpfs so that I can prolong the life of the SSD.
I've tried using "lsof" command to figure out what's active, but I really
don't understand what I'm seeing. Any further guidance would be
appreciated!

As others have suggested, swap partitions would be a good thing to
check. Also, make sure you're using noatime, to stop the files being
updated every time they're accessed (read).

I ran<br>
find / -mmin -60 -ls | grep proc -v | grep dev -v <br>
to find the files updated in the last hour when I was converting a
machine to run off a usb drive.<br>
