[LU-2376] Need a sanity check to ensure readable proc files are readable

Sun, 10 Mar 2013 18:18:32 +0000

Lustre proc has gotten a little out of whack (see ~~LU-2358~~, ~~LU-2359~~, ~~LU-2360~~, ~~LU-2263~~). It seems worthwhile to add something like the following to sanity:

for dir in /proc/{fs/{lustre,ldiskfs},sys/{lustre,lnet}} ...; do
  if [ -d $dir ]; then
    find $dir -type f -readable -print -exec cat {} \; > /dev/null
  fi
done

It would be even better if the test failed when one of the reads returned an error. Of course before such a test can be landed the four issues listed above need to be addressed.
