does this mean the drive is going bad?

 

I believe this is my cache drive, since it says ata5 would that mean it is host5 in the device list?

 

also how would I go about replacing it? Do I just copy all the data off then unmount it then add the new drive remount and copy the data back on?

 

I am running a couple apps in a .custom folder

Run a smart test and add a syslog to identify ata5 by the serial number, also reseat power and SATA cables to the drive.  I got similar read errors yesterday, and saw the pending sectors reallocated increase from 0 to 50 in a short period.

I think the drive is bad, I have gone through so many of those drives it's crazy. I am just going to replace it. But can you give me an idea on the best way to replace it?

 

I am thinking i would just do this

 

Copy and data off the drive.

 

Unmount all the drives and stop the array

 

remove the cache drive from the devices tab

 

shutdown server and replace the cache drive with the new one

 

readd it to the devices tab

 

then copy the data back to the cache drive and it should move anything that i copied off at night as usual

 

this correct?

ata5 is not likely disk5. Post a complete syslog.

I found out which disk it was, it was that seagate that was my cache drive. I replaces it and all is well now.
