Weeding out hard drives

[xman111]

hey guys quick question.  I have my main server and a backup server.  I just bought a couple 4tb drives to upgrade a few drives in my main server.  how do I go about figuring which of my drives are most needing of replacing?  which are able to move to my backup server, and which should be trashed? 

 

the smart reports are so complicated with I'm sure some unimportant info. Also how do I tell what are old errors after I acknowledge them?

If you want help with the SMART reports you need to post them.

I will post them for sure, that will help.  wanted to be able to do it myself in the future.  I have so many drives, I want to tier them.  ie. good for main server, good for backup server, good for nothing.

There are various sites on the web that explain SMART, e.g.:

here is my diagnostic zip..  any way someone could have a quick look at it and rank my drives?

All look fine, disk3 shows some issues, nothing to worry about for now, but if I had to chose the 1st one to replace that would be it.

 

Then go by power-on-hours or size, i.e., replace the older and smallest first.

Johnnie,

 

thanks man for having a look..  what specifically was worrisome about disk 3?    would it be ok to move to my 2nd server or time to retire it?   The thing I don't understand is, is my data ok on the other disks too since disk 3 is involved in the whole parity calculation.

There are some older command timeout errors and some high fly writes, neither is good but by themselves and like I mentioned nothing to worry about for the moment.

maybe i will just replace the disk and put into my backup server..  thanks so much for your time johnnie..
