Write a file until the child file system is full. 32# 2. Ensure that ENOSPC is returned. 33# 3. Unmount the child file system. 34# 4. Issue df -h command. 35# 5. Ensure pool root filesystem is included (issue #8253). 36# 6. Issue df -h <filesystem>. 37# 7. Ensure size and used are non-zero. 38# 39 40verify_runnable "both" 41 42log_onexit default_cleanup_noexit 43 44log_assert "Correct df output is returned when file system is full." 45 46default_setup_noexit $DISK_SMALL 47log_must zfs set compression=off $TESTPOOL/$TESTFS 48 49log_note "Writing file: $TESTFILE0 until ENOSPC." 50file_write -o create -f $TESTDIR/$TESTFILE0 -b $BLOCKSZ \ 51 -c $NUM_WRITES -d $DATA 52ret=$? 53 54(( $ret != $ENOSPC )) && \ 55 log_fail "$TESTFILE0 returned: $ret rather than ENOSPC." 56 57log_must zfs umount $TESTPOOL/$TESTFS 58 59# Ensure the pool root filesystem shows in df output. 60# If the pool was full (available == 0) and the pool 61# root filesystem had very little in it (used < 1 block), 62# the size reported to df was zero (issue #8253) and 63# df skipped the filesystem in its output. 64log_must eval "df -h | grep $TESTPOOL" 65 66# Confirm df size and used are non-zero. 67size=$(df -h /$TESTPOOL | awk -v p=$TESTPOOL '$0 ~ p {print $2}') 68used=$(df -h /$TESTPOOL | awk -v p=$TESTPOOL '$0 ~ p {print $3}') 69if [[ "$size" = "0" ]] || [[ "$used" = "0" ]] 70then 71 log_fail "df failed with size $size and used $used." 72fi 73log_pass "df after ENOSPC works as expected." 74
