Better checksum error reporting in ZFS
After all the discussion about filesystems and checking them after errors, i want to point to a small extension: Since the introduction of the changes proposed by “PSARC 2009/497: zfs checksum ereport payload additions”, error messages of ZFS because of checksum errors are much more informative. The extended message to the fault management gives you much more information about the issue:
With this kind of information, you can get much better image of the the problem than just from the message “checksum error”. You will find a deeper look into this change in the description of the change request <a href=”“http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6867188”>6867188</a>. An overview of the meaning of the new values in the error report is available in the PSARC case documentation.
