[LU-7657] sanity-krb5 test_151 fails with 'mount with default flavor should have failed'

Tue, 14 Dec 2021 22:21:09 +0000

Running the sanity-krb5 test suite on Lustre systems with a separate MGS and MDS on the same node or running with a combined MGS/MDS, test 151 fails with

'mount with default flavor should have failed'

This does not happen when running with a MGS and MDS on separate nodes. From the test_log, we can see that the complaint is that the MDS is already mounted:

Starting mgs:   /dev/vda3 /lustre/scratch/mdt0
pdsh@eagle-51vm6: eagle-51vm1: ssh exited with exit code 1
pdsh@eagle-51vm6: eagle-51vm1: ssh exited with exit code 1
Started scratch-MDT0000
Starting mds1:   /dev/vda3 /lustre/scratch/mdt0
eagle-51vm1: mount.lustre: according to /etc/mtab /dev/vda3 is already mounted on /lustre/scratch/mdt0
pdsh@eagle-51vm6: eagle-51vm1: ssh exited with exit code 17
Start of /dev/vda3 on mds1 failed 17
eagle-51vm1: mgc.*.mgs_server_uuid in FULL state after 0 sec
 sanity-krb5 test_151: @@@@@@ FAIL: mount with default flavor should have failed

It seems like the test code expects to start the MGs and MDS separately. From test 151:

       stopall

        # start gss daemon on mgs node                                          
        combined_mgs_mds || start_gss_daemons $mgs_HOST "$LSVCGSSD -v"

        # start mgs                                                             
        start mgs $(mgsdevname 1) $MDS_MOUNT_OPTS

        # mount mgs with default flavor, in current framework it means mgs+mdt1\
.                                                                               
        # the connection of mgc of mdt1 to mgs is expected fail.                
        DEVNAME=$(mdsdevname 1)
        start mds1 $DEVNAME $MDS_MOUNT_OPTS

Should this test be skipped for a combined MGS/MDS set up?
