Re: [libvirt] [PATCH] storage: Report error when using metadata prealloc with non-qcow2 volumes

We already report error from backend (virStorageBackendCreateRaw, virStorageBackendCreateBlockFrom), but we should also report the same error (applies to raw formated volumes and block type volumes as well) when creating a volume from a XML, not only from an existing volume. --- src/storage/storage_driver.c | 16 ++++++++++++++++ 1 file changed, 16 insertions(+) diff --git a/src/storage/storage_driver.c b/src/storage/storage_driver.c index ac4a74a..b519011 100644 --- a/src/storage/storage_driver.c +++ b/src/storage/storage_driver.c @@ -1803,6 +1803,22 @@ storageVolCreateXML(virStoragePoolPtr obj, goto cleanup; } + if (flags & VIR_STORAGE_VOL_CREATE_PREALLOC_METADATA) { + if (voldef->target.format == VIR_STORAGE_FILE_RAW) { + virReportError(VIR_ERR_CONFIG_UNSUPPORTED, + "%s", _("metadata preallocation is not supported for " + "raw volumes")); + goto cleanup; + }
