Saw this in the syslog after a warning came up

Dashboard reports an error, Smart Self Test is reporting OK (am now running an extended test)

 

 

Diagnostics attached....and if it's somehow ok, can I clear the error

 

TIA,

Run an extended SMART test on that disk.

yup, as I said in the original post, am doing that already and will post what it comes back with. Thanks

I have no idea what this means but I’m presuming replaced the disk immediately?

 

 

Here’s the downloaded report

tower-smart-20240123-0833.zip

Not sure if the screenshot shows the drive has failed.  Normally the section that really matters is this one:

SMART Extended Self-test Log Version: 1 (1 sectors)
Num  Test_Description    Status                  Remaining  LifeTime(hours)  LBA_of_first_error
# 1  Short offline       Completed without error       00%     26203         -
# 2  Extended offline    Completed without error       00%     26117         -

That shows the last extended test completed without error.  You should probably now run another one to see if it still passes as that tends to be the best indication of drive health, and failing that is almost invariably accepted as a reason for a RMA (assuming the drive is still under warranty).

Perfect, will run another test and thanks for the reply.

 

I should have a mentioned that one of my drives has a broken piece of plastic on the connection which i had to bodge fix with some hot glue so i wonder if that’s the fail point even though the server hasn’t moved in over a year. 

 

Will run another extended text.

Yes - If there is something interfering with the connection to the host this may mean the drive needs replacing even though otherwise it may be perfectly healthy.  If the drive passes the extended test (which checks its internals thoroughly) maybe it is worth looking at that connector again before scrapping the drive.

I meant to replace that drive anyway, but I’m always terrified of shutting the server down as last time it went into hang on shutdown and I had to force shutdown which was a whole other nightmare!
