I have md5sums on a lot of the files and it looks like maybe 5% of
my files are corrupted. Does anyone have any ideas?
Michael,
as far as I can see, your setup does not mee the minimum
redundancy requirements for a Raid-Z, which is 3 devices.
Since you only have 2 devices you are out on a limb.
Please read the manpage for the zpool command and pay
close attention to the restrictions in the section on raidz.
I was under the impression that zfs was pretty reliable but I
guess with any software it needs time to get the bugs ironed out.
ZFS is reliable. I use it - mirrored - at home. If I was going to
use raidz or raidz2 I would make sure that I followed the
instructions in the manpage about the number of devices
I need in order to guarantee redundancy and thus reliability,
rather than making an assumption.
You should also check the output of "iostat -En" and see
whether your devices are listed there with any error counts.
