ZFS checksum errors: what files are affected?

  • 772

Here is a zfs pool with checksum errors:

    NAME        STATE     READ WRITE CKSUM
    pool0       ONLINE       0     0    42
      c1t1d0    ONLINE       0     0    30
      c1t2d0    ONLINE       0     0    19
      c1t3d0    ONLINE       0     0    16
      c1t4d0    ONLINE       0     0    24

errors: Permanent errors have been detected in the following files:

    pool0/scratch:<0x80>

Is there a way to find which files / metadata have blocks with checksum errors?

    Normally, the path and name of the file with the error would be displayed, the <0x80> suggests the corrupted file was deleted (before or after the error). It is a reference to the indirect block that contained the file. This suggests that no active files were corrupted, just a file that was already deleted, or has since been deleted.
