Depends what you mean by "dynamic". Experience shows that most users really don't want all this to happen without manual intervention (particularly on shrink). However, we have the mechanics in place. Just send ASC/Q 2A/09 and it can get vectored up to LVM which resizes the volume and can be scripted automatically to resize the filesystem. hypervisor people tend to have problems with scripting, so there are some hacks that do this outside of the normal event system ... see for example virtio_scsi.c James -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
