Hi Anand.

Here is my script (no heckling - I know I do not produce beautiful code :)), and below is the invocation I used:

# description:  # Gluster server script to check brick extended attributes
# J. Burnash 2011
#     $Id$

while getopts  "a:b:ehsw" flag
        case $flag in
                a) attribute=$OPTARG;
                b) brick=$OPTARG;
                e) ECHO_CMD="-n";
                s) SORT_CMD="sort -k 2";
                w) brick_parent="read-write"
                h) progname=$(basename $0);
                   echo "$progname: Usage:";
                   echo "$progname <-a attribute> <-b brick> hostname1 <hostname2> ... <hostnameN>";
                   echo "where  -e puts the hostname at the beginning of the output from the requested comand,";
                   echo "       -a <attribute name> sets the extended attribute to be displayed,";
                   echo "       -b <brick name> sets the brick for which extended attributes are to be displayed,";
                   echo "and    -h gives this help message";
                   echo "the brick and attribute arguments may be enclosed in quotes to allow multiple matches for each host";
                   echo "Example: $progname 'service nitemond restart' hostname1 <hostname2>"
                *) echo "Unknown argument $flag";
        # Debug
        #echo "Flag=$flag OPTIND=$OPTIND OPTARG=$OPTARG"

# Dispose of processed option arguments:
shift $((OPTIND-1)); OPTIND=1

loop_check -f $ECHO_CMD "cd /export/$brick_parent; for brick_root in $brick; do echo -n \$HOSTNAME; getfattr -d -e hex -m $attribute \$brick_root |  xargs echo | sed -e \"s/# file:/ /\" ; done" $@ | awk '{print $2,$3,$1}' | $SORT_CMD

Invocation: check_brick_attrs_ro -e -s -a trusted.afr -b 'g0{1,2}' jc1letgfs{14,15,17,18}

Can you give your script or explain what each of those fields mean and how they fit into your volume configuration? Also can you post your client volfile?
