Device: /dev/ada4, 2 Currently unreadable (pending) sectors

[antsrealm]

I have received this email message today.

Code:

his message was generated by the smartd daemon running on:
 
  host name:  freenas
  DNS domain: local
 
The following warning/error was logged by the smartd daemon:
 
Device: /dev/ada4, 2 Currently unreadable (pending) sectors
 
Device info:
WDC WD30EZRX-00MMMB0, S/N:WD-WMAWZ0418179, WWN:5-0014ee-206f8271f, FW:80.00A80, 3.00 TB
 
For details see host's SYSLOG.
 
You can also use the smartctl utility for further investigation.
No additional messages about this problem will be sent.

What should I do from here ?

Also here is a copy and paste from the shell that is in the web interface:-

What should I do from here. This server host stuff for my small business so it's important I get this back to 100%

Thanks,

After doing a read around the forum it looks like this is grounds to replace the disk and I should do so Immediately. At the moment I have all WD green disks, is there any problem with replacing the failed green disk with a WD red as that is the path I would like to take (I think :p)

 

[Scareh]

you can swap green and reds all around, don't worry about that.
You should read cyberjock's signature on why Raidz1 is dead and use Raidz2, especially if its bussiness data, which seem to be important

Yeah I want to change to Z2 I'm aware of the need but it's not possible to add an extra HDD to the current pool is it ? Also I have a pending upgrade where I will replace everything to the preferred hardware (ECC Ram etc.) just not quite there yet.

 

[gpsguy]

Yes, that is correct.
