acurcione Posted May 20, 2016 Share Posted May 20, 2016 I added a new drive (4TB WD Red) to the array so I can use it to do the file system swap thing so first thing I did was try to preclear it. I used the plugin this time instead of doing it on the console and I just used it with the defaults. I'm pretty sure when I first built this in 2014 I used some parameters with the preclear script, but darned if I can remember what or why. Anyway, I ran a 3 pass preclear and after 84+ hours it says it failed because it detected non-zero bytes. I have no idea what to do at this point. Should I run it again with some parameters? If so, could someone enlighten me as to what cause I can't seem to find that part anymore. Attaching the output from the preclear. It doesn't seem to allow me to paste it all in here. Also, before anyone says check RAM, I recently did a 3 hour memtest at someones suggestion for trying to determine the cause of another issue which led to me wanting to change the file system over to XFS. The memtest came back fine, BTW. Just found this, if it helps: = Post-Read in progress: 99% complete.
