I was rsync'ing data from one system to another, and the recipient suddenly started throwing DRDY errors. Now, it's a fairly new WD Red 3TB, and I'd think it was just a bad drive... but I'm really confused by this, from the logs: Jun 15 15:34:43 <servername> kernel: ata3: SError: { Dispar }
Dispar? And googling, every reference I find to that word always has something else there.
dispar = disparity
different, dissimilar, not same, unequal, unlike.
what is/are complete line/s that show dispar err?
Any thoughts?
your drive may be flaking.
back up drive with errs, run a non destructive test on drive.
do you have smartd running? if so, check /var/log/messages or /var/log/syslog.
if you are not running smartd, start running smartd.
