As a point of reference, the aforementioned lvcheck doesn't seem to
find any corruption on the same device and here is what it's doing:

…
+ lvcreate -s -L 256M -n almalinux8_opt-lvcheck-temp-20240104 rootvol_tmp/almalinux8_opt
  Logical volume "almalinux8_opt-lvcheck-temp-20240104" created.

The significant difference between lvcheck and e2scrub seems to be the
'-E journal_only' option to e2fsck that e2scrub is adding.

Cheers,
