of echo_client running on 1 or more nodes.
You just need to pass parameters case=network and
- server_nid="<name/nid_of_server>" to the script. The script will do the
+ targets="<hostname/ip_of_server>" to the script. The script will do the
required setup for network case.
3. The Stripe F/S over the Network.
-------
The script must be customised according to the components under test and
-where it should keep its working files. Customization variables are
-described clearly at Customization variables Section in the script.

+Please see maximum suported value ranges for customization variables
+in the srcipt.
To run against a local disk:
---------------------------
Here the obdfilter instance names are oss01-sdb, oss01-sdd, oss02-sdi.
Since you are driving obdfilter instances directly, set the shell array
-variable 'ost_names' to the names of the obdfilter instances and leave
-'ECHO_CLIENTS' undefined.
+variable 'targets' to the names of the obdfilter instances.
+
Example:
-OSTS='oss01:oss01-sdb oss01:oss01-sdd oss02:oss02-sdi' \
+targets='oss01:oss01-sdb oss01:oss01-sdd oss02:oss02-sdi' \
./obdfilter-survey
-
To run against a network:
------------------------
For the second case i.e. obdfilter-survey over network, following setup
and server machine to avoid typing password.
1. Automated run:
To run obdfilter-surevy against network you just need to pass parameter
- case=netdisk and server_nid="<name/nid_of_server>" to the script.
+ case=netdisk and targets="<hostname/ip_of_server>" to the script.
-e.g. $ nobjhi=2 thrhi=2 size=1024 server_nid="<name/nid_of_server>" \
+e.g. $ nobjhi=2 thrhi=2 size=1024 targets="<hostname/ip_of_server>" \
case=network sh obdfilter-survey
On server side you can see the stats at :
- /proc/fs/lustre/obdecho/<ost-testfs>/ststs
-where, 'ost_testfs' is the obdecho server created through script.
+ /proc/fs/lustre/obdecho/<echo_srv>/stats
+where, 'echo_srv' is the obdecho server created through script.
NOTE: In network test only automated run is supported.
2. Manual run:
While running manually you need to tell the script all the names of the
echo_client instances, which should already be up and running.
-e.g. $ nobjhi=2 thrhi=2 size=1024 ECHO_CLIENTS="ECHO_<osc_name> ..." \
+e.g. $ nobjhi=2 thrhi=2 size=1024 targets="<osc_name> ..." \
