After manys, 1st disk error

It looks like my parity disk is having issues. This thing has been running unattended so long, I think I've just about forgotten what little I knew!

 

Anyway, would like some advice before doing anything. Unraid 5.0, syslog and smart report attached.

 

Thanks!

 

Well it says the files are greater than 192KB and won't take them. Not sure how as the file sizes are 66KB, 32KB and 5KB. Anyway, try here:

So, I need to run a preclear? Does the array need to be shut down? Or does the parity disk need to be unassigned? Or can I just run it?

 

Thanks. Sorry for the questions, just kind of scary when my data is in peril!

Never mind, I've comprehended what I was reading a little better now. I'm doing the second option under re-enable drive. It is building parity now, should be finished by morning.

 

Thanks again!

You should get another SMART after and hopefully the pending will be gone, possibly changed to reallocated, which is OK as long as it isn't increasing fast.

Personally though, I would replace any drive with pending / reallocated sector asap.

If pending goes to zero and the reallocated count is small and not increasing then its probably OK just to keep an eye on it. Reallocating is a normal function for drives.

That took a while, but it's finished rebuilding and checking parity with 0 errors. Here is smart report now:

Pending is now 3 instead of 5 and reallocated is still 0. Does that mean if it tries to read from one of those 3 sectors it will fail again? Why wouldn't it reallocate them? I checked and it's under warranty until October. Is this sufficient issue to return? If not, what do I need to watch for?

An increasing number of pending is not a good thing. Personally I would use the warranty. I have utilised warranty in the past with just 1 pending sector so I'm sure 5 is 5 times more valid.
