Hi,
in ocf:heartbeat:exportfs (as found in SLES11 SP1) there is a problem with
"grep -zqs":
The "-z" is expected to fix the problem where exportfs splits a lenghty name
into two lines. Unfortunately exportfs does not output any binary zeros that
"grep -z" is looking for. Thus effectively "-z" makes grep succeed when it
shouldn't.
Source:
exportfs_monitor ()
{
# "grep -z" matches across newlines, which is necessary as
# exportfs output wraps lines for long export directory names
exportfs | grep -zqs
"${OCF_RESKEY_directory}[[:space:]]*${OCF_RESKEY_clientspec}"
[...]
Example (test):
# exportfs | grep -z h06
/home/windl/src/scripts/OCF/twuc/.git/objects/39
h02
/home/windl/src/scripts/OCF/twuc/.git/objects/39
h06
/mnt h02
/mnt h06
# exportfs | grep h06
h06
/mnt h06
So you see "grep -z" does produce false results. Probably never tested...
BTW: Shouldn't the match be "anchored"? ^$directory ... $host\$
Regards,
Ulrich
