The first time a device returns ENOTSUP in repsonse to a flush request, we set vdev_nowritecache so we don't issue flushes in the future and instead just pretend the succeeded. However, we still return an error for the initial flush, even though we just decided such errors are meaningless! So, when setting vdev_nowritecache in response to a flush error, also reset the error code to assume success. Along the way, it seems there's no good reason for vdev_disk & vdev_geom to explicitly detect no support for flush and set vdev_nowritecache; just letting the error through to zio_vdev_io_assess() will cause it all to fall out nicely. So remove those checks. Sponsored-by: Klara, Inc. Sponsored-by: Wasabi Technology, Inc. Signed-off-by: Rob Norris <rob.norris@klarasystems.com> |
