This is the IRIX way, anyway - from a bit of man page reading. We should be stitching that into -o sync a bit better in XFS. The combination of -o wsync,sync should get you the equivalent behaviour at the moment though, I think. > We are not sure if this is the expected behavior on XFS or not, so your > inputs on this are well appreciated. Try using -o wsync for your tests, I'll look into our interpretation of -o sync in XFS in the meantime. cheers. -- Nathan - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
