I'm running FreeNAS-9.2.1.7-RELEASE-x64 (fdbe9a0) on an Intel(R) Xeon(R) CPU X3470 @ 2.93GHz with 16GB of ECC RAM. I have two Crucial SSDs in a mirror.
I got two emails from the machine with the following information:
---
Email One:
The following warning/error was logged by the smartd daemon:
Device: /dev/ada0, 1 Currently unreadable (pending) sectors
Device info:
Crucial_CT960M500SSD1, S/N:14240C513F6F, WWN:5-00a075-10c513f6f, FW:MU05, 960 GB
Email Two:
The following warning/error was logged by the smartd daemon:
Device: /dev/ada1, 1 Currently unreadable (pending) sectors
Device info:
Crucial_CT960M500SSD1, S/N:14240C513F81, WWN:5-00a075-10c513f81, FW:MU05, 960 GB
---
These emails were both generated six minutes after the scheduled beginning of a scrub.
However, when I view the SMART data from the CLI, I see this:

I don't see anything regarding unreadable sectors. I also find it odd that both drives generated the same error at the same time. What does this mean? It seems from everything I know about the SMART data (which admittedly isn't much), the drives seem fine. If anyone would like to chime in, I'm all ears. Thanks in advance.
I got two emails from the machine with the following information:
---
Email One:

I don't see anything regarding unreadable sectors. I also find it odd that both drives generated the same error at the same time. What does this mean? It seems from everything I know about the SMART data (which admittedly isn't much), the drives seem fine. If anyone would like to chime in, I'm all ears. Thanks in advance.
