This seems to imply that sdd has a bad sector at 1953519813, but
md seems quite happy to rebuild the array?? Does that mean that,
by chance, it didn't use that bad sector when rebuilding, but
tomorrow it might try writing there, triggering another failure?

Try running "smart" tests on the disks: first one, check if it
needs rebuilding when it fnishes, then the other.

Sorry, can you tell me the command I need. Do I need any particular
software installed?

You need smartmontools installed - then try something like this:

smartctl -a <disk device>

/Per Jessen, Zürich

Thank you. Both devices in the array passed:

SMART overall-health self-assessment test result: PASSED


You could also run a long selftest on them:

smartctl -t long <disk device>
