For these tests let's add _require_no_o_direct() helper which can be put in the preabmle and which makes sure '-nocache' isn't set. Use it to skip running the following tests: * 271: creates files with unaligned sizes, thus producing multiple errors like: qemu-io: can't open device /path/to/t.qcow2.raw: Cannot get 'write' permission without 'resize': Image size is not a multiple of request alignment * 308, file-io-error: use fuse exports. Though fuse does have 'direct-io' mode (see https://docs.kernel.org/filesystems/fuse-io.html) we aren't using it yet, thus getting errors like: qemu-io: can't open device /path/to/t.qcow2.fuse: Could not open '/path/to/t.qcow2.fuse': filesystem does not support O_DIRECT Signed-off-by: Andrey Drobyshev Reviewed-by: Eric Blake --- tests/qemu-iotests/271 | 1 + tests/qemu-iotests/308 | 2 ++ tests/qemu-iotests/common.rc | 7 +++++++ tests/qemu-iotests/tests/file-io-error | 1 + 4 files changed, 11 insertions(+) diff --git a/tests/qemu-iotests/271 b/tests/qemu-iotests/271 index 59a6fafa2f..1424b6954d 100755 --- a/tests/qemu-iotests/271 +++ b/tests/qemu-iotests/271 @@ -44,6 +44,7 @@ _supported_fmt qcow2 _supported_proto file nfs _supported_os Linux _unsupported_imgopts extended_l2 compat=0.10 cluster_size data_file refcount_bits=1[^0-9] +_require_no_o_direct l2_offset=$((0x40000)) diff --git a/tests/qemu-iotests/308 b/tests/qemu-iotests/308 index de12b2b1b9..535455e5b1 100755 --- a/tests/qemu-iotests/308 +++ b/tests/qemu-iotests/308 @@ -52,6 +52,8 @@ _unsupported_fmt vpc _supported_proto file # We create the FUSE export manually _supported_os Linux # We need /dev/urandom +_require_no_o_direct + # $1: Export ID # $2: Options (beyond the node-name and ID) # $3: Expected return value (defaults to 'return') diff --git a/tests/qemu-iotests/common.rc b/tests/qemu-iotests/common.rc index 95c12577dd..f61eae73b4 100644 --- a/tests/qemu-iotests/common.rc +++ b/tests/qemu-iotests/common.rc @@ -857,6 +857,13 @@ _check_o_direct() [[ "$out" != *"O_DIRECT"* ]] } +_require_no_o_direct() +{ + if [ $CACHEMODE == "none" ] || [ $CACHEMODE == "directsync" ]; then + _notrun "not suitable for cache mode: $CACHEMODE (implies O_DIRECT)" + fi +} + _require_o_direct() { if ! _check_o_direct; then diff --git a/tests/qemu-iotests/tests/file-io-error b/tests/qemu-iotests/tests/file-io-error index 88ee5f670c..2b8dc7f009 100755 --- a/tests/qemu-iotests/tests/file-io-error +++ b/tests/qemu-iotests/tests/file-io-error @@ -40,6 +40,7 @@ trap "_cleanup; exit \$status" 0 1 2 3 15 # Format-agnostic (we do not use any), but we do test the file protocol _supported_proto file _require_drivers blkdebug null-co +_require_no_o_direct if [ "$IMGOPTSSYNTAX" = "true" ]; then # We need `$QEMU_IO -f file` to work; IMGOPTSSYNTAX uses --image-opts,
