Description

I talked with Hank about testing this, and he said that there's no practical way for us to cause the needs_check flag to be set on a cache. So, I think for testing this we'll just need to observe that the cache_check command is being run, and not require that it's actually clearing the flag. As for verifying that the cache_check command is run, it's hidden pretty well (which is why I failed to notice it was missing originally), so there's no simple way to observe that either. It may be simpler to verify that activation is running cache_check by actually removing the cache_check command and verifying that the command warns that it can't run it: # mv /usr/sbin/cache_check /root/. # lvchange -ay test/main /usr/sbin/cache_check: execvp failed: No such file or directory WARNING: Check is skipped, please install recommended missing binary /usr/sbin/cache_check! I assume this will be added to the errata in the next build?
