Unlike quotas however there should be no restrictions +# on accessing space outside of the limits of the reservation (if the +# space is available in the pool). Verify that in a filesystem with a +# reservation set that its possible to create files both within the +# reserved space and also outside. +# +# STRATEGY: +# 1) Create a filesystem +# 2) Get the space used and available in the pool +# 3) Set a reservation on the filesystem +# 4) Verify can write a file that is bigger than the reserved space +# +# i.e. we start writing within the reserved region and then continue +# for 20MB outside it. +# + +verify_runnable "both" + +function cleanup +{ + [[ -e $TESTDIR/$TESTFILE1 ]] && log_must $RM -rf $TESTDIR/$TESTFILE1 + log_must $ZFS set reservation=none $TESTPOOL/$TESTFS +} + +log_onexit cleanup + +log_assert "Verify can create files both inside and outside reserved areas" + +space_used=`get_prop used $TESTPOOL` + +log_must $ZFS set reservation=$RESV_SIZE $TESTPOOL/$TESTFS + +# +# Calculate how many writes of BLOCK_SIZE it would take to fill +# up RESV_SIZE + 20971520 (20 MB). +# +fill_size=`expr $RESV_SIZE + 20971520` +write_count=`expr $fill_size / $BLOCK_SIZE` + +log_must $FILE_WRITE -o create -f $TESTDIR/$TESTFILE1 -b $BLOCK_SIZE \ + -c $write_count -d 0 + +log_pass "Able to create files inside and outside reserved area" |
