This is the first time I've used a solid state drive. It looks like
there's some kind of compatibility or interface problem. The output
from smartctl -x also points to some kind of interface problem.
ZFS counted about 180 write errors while resilvering ~80GB. Most seemed
to be retryable and succeeded on the second try (see logs below).
The system is using AMD-AHCI, not IDE.
The SATA interface is running at 3.0Gb/s, half the SSD's 6.0Gb/s speed.
Temperature is fine (~29C).
So far, the errors only occur during heavy activity: write errors during
resilvering, and 2 read errors later during a brief burst of read
activity.
[Note: I swapped the SATA cables: that's why ada1 during resilvering
became ada0 later. Since I swapped cables at the drive end, not the
motherboard end, I think it unlikely to be a cable/bad connection problem.]
Any ideas what the problem might be? Thanks,
-WBE
