Description

conf-sanity test_82b fails when Lustre is configured with the MGS and MDS on separate nodes with

conf-sanity test_82b: @@@@@@ FAIL: /usr/sbin/lctl pool_add scratch.test_82b scratch-OST[32b4,06a8,7070] failed

From the console log, it looks like the OST pools are never created

eagle-48vm1: Warning, pool scratch.test_82b not found
eagle-48vm1: Pool scratch.test_82b not found
eagle-48vm1: Pool scratch.test_82b not found

 conf-sanity test_82b: @@@@@@ FAIL: /usr/sbin/lctl pool_add scratch.test_82b scratch-OST[32b4,06a8,7070] failed 

test 82b checks that you can create OST pools with the –ost-list option. For OST pools to work with the MDS and the MGS on separate nodes, there must be a client running on the MGS. The problem is that all clients and servers are stopped at the beginning of the test and then only a single client is started. That single client may or may not be the client on the MGS.

From conf-sanity test 82b:

5846         # Setup Lustre filesystem.
5847         start_mgsmds || error "start_mgsmds failed"
5848         for i in $(seq $OSTCOUNT); do
5849                 start ost$i $(ostdevname $i) $OST_MOUNT_OPTS ||
5850                         error "start ost$i failed"
5851         done
5852 
5853         mount_client $MOUNT || error "mount client $MOUNT failed"

One solution to this problem is to restart all clients in this test.
