WRITE_DMA errors on SATA drive under 5.3-RELEASE

I've gotten two messages like the ones below today on my production server

messages:Feb 27 14:48:17 freebie kernel: ad10: TIMEOUT - WRITE_DMA retrying (2 retries left) LBA=4848803
messages:Feb 27 14:48:17 freebie kernel: ad10: FAILURE - WRITE_DMA timed out

What do these messages mean?  The referenced drive is one of two identical SATA
drives on the server; it holds /tmp and /var.  I don't recall seeing
these messages before.

Is there a way to work backwards from the LBA to the filesystem so that
I can see which file was being referenced when this occurred?
