[LU-15906] setupall function under test-framework never fails

Tue, 14 Jun 2022 14:39:12 +0000

setupall function under test-framework never fails. Even if the mount from mount[mgs/oss] or mount_facet() call is a faiure. Somewhere within a chain of calls from setupall() to do_nodes() the return value is getting washed away and 0 is returning

Reproducer:

test_1400() {                                                                  
sync; sync_all_data; sleep 3; sync_all_data                             
echo "********** Stopping"                                              
stopall                                                                 
# options passed is on purpose given will fail                          
# as rdonly_dev is not supported                                        
MGS_MOUNT_OPTS=$(csa_add "$MGS_MOUNT_OPTS" -o rdonly_dev)               
MDS_MOUNT_OPTS=$(csa_add "$MDS_MOUNT_OPTS" -o rdonly_dev)               
OST_MOUNT_OPTS=$(csa_add "$OST_MOUNT_OPTS" -o rdonly_dev)               
echo "................starting again!!! ............"    
setupall server_only || error "FAILED SETUPALL!!!"                                                     
echo "Return Value = $?"  
}                                                               
run_test 1400 "Sample test to demonstrate setupall never fails"
