I've noticed something strange over the past few months with four files
on my raidz. Here's the setup:
OpenSolaris snv_111b
ZFS Pool version 14
AMD-based server with ECC RAM.
5 ST3500630AS 500 GB SATA drives (4 active plus spare) in raidz1
The other day, I observed what appears to be undetected

Why don't you see which byte differs, and how it does?
Maybe that would suggest the "failure mode". Is it the
same byte data in all affected files, for instance?

Since these were my offsite backups I was using Truecrypt which drove the use
of ext3 and Linux. Also I wanted
Just to close out the discussion, I wasn't able to prove any issues with
ZFS. The files that were changed all seem to have plausible scenarios.
