This issue was added by the patch for 826 827 local cmd="$WRITE_DISJOINT -f $testdir/file -n $wdisjoint_REP -m "\ 828 "$chunk_size_limit" 829 830 echo "+ $cmd"
From the suite_log, we can see that the value of the –m flag never makes it to the write_disjoint command and is interpreted as a standalone line == parallel-scale test write_disjoint: write_disjoint ================================================ 11:43:29 (1519386209) OPTIONS: WRITE_DISJOINT=/usr/lib64/lustre/tests/write_disjoint clients=trevis-3vm1.trevis.hpdd.intel.com,trevis-3vm2 wdisjoint_THREADS=4 wdisjoint_REP=10000 MACHINEFILE=/tmp/parallel-scale.machines trevis-3vm1.trevis.hpdd.intel.com trevis-3vm2 /usr/lib64/lustre/tests/functions.sh: line 828: local: `123456': not a valid identifier + /usr/lib64/lustre/tests/write_disjoint -f /mnt/lustre/d0.write_disjoint/file -n 10000 –m
The problem is the line continuation at the end of line 827; we just need to remove the end quotation on line 827 and first quotation on line 828. The reason why the code doesn’t work as it is, is due to the tab/spaces on line 828.
I’ll upload a patch for this. |
