  1. @tyrindor. Others including myself have reported the slower parity checks. Tom made mention of unraid polling the drives every 10seconds,which was changed in rc9. But simplefeatures also utilizes this in the disk health plug in. Don't know if this is related, but I plan to test by disabling.

    This was my original report after upgrading to rc5,Btw I believe the slow writes and parity checks have separate root causes.

  2. Smart reports will state "pass" when the attributes each exceed the "THRESH" value.  Passing may mean nothing.

     

    Parity:

  3. A few days ago I went to access some of my data and I noticed entire user shares that were empty...this didn't make much sense.

    Checking the unRAID web interface I saw that one of my drives was marked RED and it indicated 7 errors.

    2 other drives in the array also showed errors (one with 93 errors, the other with 69 errors) but they were still green.

     

    The first drive had a write failure, and was mounted read only. The other 2 likely had a read failure due to ?? (could be a number of reasons). Post smart reports for all of your drives, and syslog..and that will give the clues to why they "failed"
