Once a file has been deleted, ZFS can have a hard time determining its
filename.

It is inode 198186 (0x3062a) on dataset 0x102. The file has been
deleted, but still exists in at least one snapshot.

Although, 57 million checksum errors seems like there may be some other
problem. You might look for and resolve the problem with what appears to
be a raid5 you have built your ZFS pool on top of it? Then do 'zpool
clear' to reset the counters to zero, and 'zpool scrub' to try to read
everything again.
