$ zpool status -v
pool: pond
state: ONLINE
status: One or more devices has experienced an error resulting in data
corruption. Applications may be affected.

entire pool from backup.

errors: Permanent errors have been detected in the following files:
/usr/src/cscope.out
I don't see any errors or suspicious messages in any logs.
The file in question is perfectly readable (produces stable md5 checksum without
any errors) and apparently is not too (or at all) corrupt - cscope still works
fine with it.
All vdevs are online and there are no vdev errors.
So what does all this mean and how it can happen?
In other words, why/how did ZFS decide that that file is corrupted?
