I have 2x ST32000542AS 2TB

 

I see some values that I think is bad.

I need to change this drives before crash? Server alarm about 'Command Timeout' on this two drives

 

I don't like values Raw Read Error Rate and Seek Error Rate and Hardware ECC Recovered

 

What do you think?

 

And if I want to change this 2 drives with 1 6TB(Yes I Have 6TB drive on parity, I can add 6TB drive data)

what is the procedure?

This suggests that you want to remove the number of drives in the array?  I assume they also have data on them you want to keep?  There is not a supported way of doing this while maintaining parity so while doing this your data is not protected against drive failure.  The standard procedure would be:

  • Stop the array
  • Make a copy of the config folder (this will help with recovery if things go wrong).  Make sure you know which drive is the parity drive.
  • Assign the drives you now want (omitting the drives to be removed) making sure you get the parity drive right.  Optionally you can omit the parity drive at this stage and add it in later.
  • Start the array.  Existing drives should come up with their data intact.  The 'new' drive will show up as unformatted/unmountable.  It needs to be formatted before you can put data on it. 
  • If you originally included the parity drive then the system should be calculating the parity.  If you omitted the drive, stop the array; add the parity drive; and start the array to calculate parity.
  • When the parity calculation finishes run a parity check to make sure it was done OK.  This should complete with no errors.

You can now need to copy the data from the disks you removed (assuming they were not empty) back to the array.  The best method for doing this varies according to whether the disks will be attached to the unRAID server or somewhere else and data copied across the network.

 

NOTE:  There is a way of removing drives while maintaining parity, but it requires that the drives have no data on them and also requires running Linux commands to 'zero' the drive that could cause data loss if you got them wrong.

This value.. what's mean?

188  Command Timeout  0x0032  100  098  000  Old age  Always  Never  8590065719

 

The key number there is the 100 (the VALUE), which means it's essentially perfect.  At some time in the past, it dropped to 098 (the WORST), which is still a long way from 000 (the THRESH).  And 'Old age' means it is informative, but not considered a critical attribute.  Critical attributes are marked 'Pre-fail'.

Well for your answers I can understand that the drives are OK, and yet I can use on my unRAID server.

Thanks for all

 

If you are interested in knowing about SMART attributes, you should probably be reading this article.  It can answer many of your questions:

 

    https://en.wikipedia.org/wiki/S.M.A.R.T.

 

Remember the each manufacturer interprets and implements these attributes a little bit differently...
