Hi, Corey,

I'm in the process of rolling out the upgrade from (mostly) 5.3 to 5.4. One of my servers started throwing the following: Nov 1 05:22:51 <server> kernel: target4:0:0: FAST-80 WIDE SCSI 160.0 MB/s DT (12.5 ns, offset 62) Nov 1 05:22:51 <server> kernel: target4:0:1: FAST-80 WIDE SCSI 160.0 MB/s DT (12.5 ns, offset 62)
into my logs every half hour. I don't see anything resembling an error message. The only thing I noted while googling was everyone else spoke of "...ns, offset 127", but I have no clue if that's relevant to anything. The smartd.conf is the default. I'm not running the debug
kernel.
Does anyone have any idea why it's doing this, and, if it's not important, how to get it to stop cluttering my logs?
What do you see when you run a smartctl -a $DEVICE on the drive that's choking?
Wasn't sure if I should run it on /dev/sdx, or /dev/sdx[#]. I did both, on all three drives, and no errors showing anywhere - the latter two (on /dev/sdb and /dev/sdc) show no uncorrected errors, and no errors corrected by ECC. /dev/sda gives me a lot more output, but says no errors logged.
I don't really understand why sda gives so much more info, nor do I understand the o/p at the beginning. The headers for the second section read: SMART Attributes Data Structure revision number: 10 Vendor Specific SMART Attributes with Thresholds: ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE
and there are numbers under RAW_VALUE, but are those the values of the manufacturer's limits? Certainly, there is nothing but dashes under WHEN_FAILED.
Do you need more info?
