Hey Guys,
I made a post the other day regarding this but it's a different question. Essentially i've had this 4 disk raidz1 running for 1.5 yrs no issues, I then upgraded Freenas to 8.3 and my zpool to 28. Within the week all my disks were showing checksum errors, after a full scrub the results were 2/7/1/2.
Here is my logic.. It can't be the disks/cables because previously there was 0 in all of them, they can't all be damaged at once.. In fact I doubt it's hardware at all because of that fact although if it is then it's probably the RAM or Controller. That week I had Freenas randomly reboot, perhaps crashed.. So I am thinking that crash created some file corruption unrelated to the hardware.
I ran a full scrub, said it fixed 440k in errors. They came back, running another full scrub and they are still there. Can anyone shed light on this?
Thx
