>Description:
When requesting the gmirror status of a non existant device the gmirror utility exits with a 0 exit status which according to the man page indicates that the command completed successfuly.
>From man 8 gmirror:
EXIT STATUS
Exit status is 0 on success, and 1 if the command fails.
I would have thought the command has failed if the device of whom the status is being requested does not exist.
>How-To-Repeat:
Assuming gm0 is not an active gmirror device, and is not listed in the output of "gmirror status"
gmirror status gm0; echo $?
No such geom: gm0.
0
>Fix:
It would seem that the gctl_req structure has members that allow for storing of error states perhapse these could be used in the cases where error conditions are found (std_list, std_status etc...). Or exit(EXIT_FAILURE) could be called.
>From sbin/geom/core/geom.c I seems that neither "Class not found" or "No such geom" cause exit(EXIT_FAILURE), where ase "Cannon get GEOM tree" does.
