Description

The following huge output of test_133g is not correct. It means "find" does not include its "-name $PARAM" argument.

 

== sanity test 133g: Check reads/writes of server lustre proc files with bad area io ========================================================== 16:13:38 (1683821618)

# proc_regexp="/\{proc,sys}/\{fs,sys,kernel/debug}/\{lustre,lnet}/"
# proc_dirs=$(eval ls -d $proc_regexp)

 

After running the upper commands, 'echo "$proc_dirs"' woud print
multiple lines like what sanity test 401a would print:

proc_dirs='/proc/fs/lustre/
/sys/fs/lustre/
/sys/kernel/debug/lnet/
/sys/kernel/debug/lustre/'
