I just started replacing drives in this zpool (to increase storage). I pulled
the first drive, and replaced it with a new drive and all was well. It
resilvered with 0 errors. This was 5 days ago. Just today I was looking around
and noticed that my pool was degraded (I see now that this occurred last
night). Sure enough there are 12 read errors on the new drive.
I'm on snv 111b. I attempted to get smartmontools workings, but it doesn't seem
to want to work as these are all sata drives. fmdump indicates that the read
errors occurred within about 10 minutes of one another.
Is it safe to say this drive is bad, or is there anything else I can do about
this?
Thanks,
Jon

That first log is the original drive being replaced. The second is the read
errors on the new drive.
