How does one fit more than one 2 tb slice into a 2.5 tb array? ;-)

You might want to be somewhat more specific about the errors.

Nevertheless, have a look at the da(4) manpage. It mentions some sysctls
that might affect the situation. You could also inspect the device's
parameters in its mode pages using camcontrol(8).

If the errors are related to the filesystem, do they mention any of the
inconsistencies mentioned in the fsck_ufs(8) manpage?

If you want to check the filesystem, there is no alternative for
fsck_ufs(8). If you invoke it with the '-p' flag first, it will only
repair a limited number of errors.

If that exits with a non-zero status, you'll have to run a full
foreground test.
